Background

In the pulping and papermaking industry, the currently generally adopted treatment method for waste paper raw materials or natural plant fiber raw materials which are difficult to break is that excessive NaOH and 27.5 percent H are added simultaneously under the action of the mechanical force of pulping₂O₂(or 22.5 percent of NaClO), pulping enzyme, naphthalene sodium sulfonate, sodium lignosulfonate and other pulping aids are added, and the mixture is treated by methods such as high-temperature causticization, oxidation, dispersion and the like.

However, the method has poor treatment effect, and in the process of treating waste paper, excessive NaOH and 27.5 percent of H are adopted₂O₂(or22.5% NaClO) and other adjuvants, generally leading to the results: the plant fiber is causticized, peeled and corroded in a large amount; the yield of paper pulp is low; the waste paper of chemical fiber or blend fiber has no practical treatment effect at all. The research shows that the method can reduce the yield of the paper pulp by 15.0-20.0%; the comprehensive strength of the paper pulp fiber is reduced by 25.0-40.0%; the fiber is causticized in a large amount, so that the feeding cost of a papermaking enterprise is greatly increased, the environment-friendly quality is not improved, and the defects of low economy and the like are overcome.

The waste paper used in the pulp and paper making industry is of various types, the performances of various papermaking aids (papermaking chemicals, chemical materials containing functionality) contained in the waste paper are different, and the chemical components of the functional papermaking aids contained in the waste paper raw materials of different types are also different. The inventors conducted extensive and exhaustive studies on the existing waste papers, as summarized below:

(1) waste paper of various packing paper

In the waste paper of this type, most of the chemical components that are solidified and adsorbed on the fibers are functional high molecular polymers, and all of them are solidified in the waste paper in a cationic form. The specific types are as follows: the adhesive comprises a polyamide polyamine-epichlorohydrin resin (containing melamine formaldehyde, urea formaldehyde, polyethyleneimine and the like) wet strength agent, a polyvinyl amine dry strength agent, a stearic acid grafted polyamide polyamine retention aid, a polystyrene-acrylate copolymer surface sizing agent, an AKD internal sizing agent and the like. In addition, there are coated carboxylated styrene-butadiene latex and paint.

(2) Waste paper for various cultural papers

Similar to (1), the chemical component types of the waste paper of the present type are generally: various retention and drainage aids, various dry strength agents, various surface sizing agents, AKD internal sizing agents, and the like, and dispersion-type rosin sizing agents are sometimes used.

(3) Various household paper waste paper

In the waste paper of the type, the added chemical components are mainly as follows: various wet strength agents, various reinforcing agents, nonionic polyacrylamide dispersants, various softening agents and the like.

(4) Waste paper of various special papers

The waste paper of the type is basically the same as the functional high molecular polymer papermaking auxiliary agent contained in the waste paper of the packaging paper, but the content of chemical components in the waste paper is 5.0 to 7.0 times higher than that of the waste paper of the packaging paper.

(5) Used waste paper after various post-processing

The surface of the waste paper of the type mostly contains different types of polishing oil, polyethylene wax, carboxylic styrene-butadiene latex, styrene-acrylic emulsion, oily ink, water-based ink, base materials and the like.

The solubility properties of various functional papermaking aids contained in the above five types of waste papers, including the respective occupation ratios of oil-soluble and water-soluble aids, are shown in table 1, for example:

TABLE 1 basic characteristics exhibited after various chemical components contained in waste paper are adsorbed to fiber and solidified

Based on the physicochemical properties, functional characteristics, and uses of the chemical components of the polymers contained in the above-mentioned five types of waste papers, the following basic characteristics can be roughly summarized here:

(1) the waste paper containing excessive cationic functional polymer components has great binding force between fibers and high fiber strength, and is difficult to degrade in the condition of using alkali oxide water solution as medium.

(2) The waste paper is not easy to be disintegrated in the initial stage under the action of the medium of alkaline oxide aqueous solution and the mechanical force, and the waste paper is infiltrated and defibered under the action of the mechanical force after a certain time; however, the disintegration time is longer, and generally more than 2.50 hours are needed.

(3) The waste paper contains too many functional cationic polymer auxiliary agent components, the content of the film-forming water-resistant auxiliary agent is also higher, and the waste paper raw material fibers have strong binding force, high strength performance and excellent water resistance; even if the waste paper is treated under the action of mechanical force and under the condition of mixed aqueous solution of strong alkali and oxide or with biological pulping enzyme, the waste paper is not helpful at all and has no substantial effect.

The three "all" rules are three basic rules obtained by the inventor through extensive systematic research and summary of a large number of scientific experiments and production practices.

Based on the research, in order to obtain the fiber defibering agent with excellent defibering performance, the invention adopts the measures that the HLB (hydrophilic-lipophilic value) value of the defibering agent is adjusted to be 6.5-9.5; the object is achieved by using nonionic emulsifiers of the o/w type. In addition, the nonionic surfactant with stronger electrostatic repulsion is adopted, so that the activity and electrostatic repulsion effect among fibers are increased to the greatest extent in the pulping process, and the optimal pulping efficiency is strived to be achieved.

In particular, the hydrophilic-lipophilic (HLB) type of emulsifier must have the following characteristics:

(1) excellent permeability, and the specific surface area of the permeability needs to reach more than 1.0:100.0 within 1.0 minute;

(2) excellent antistatic properties, in terms of PCD values; diluting paper pulp to 4.0-4.5% concentration with water after 1.0 ton waste paper raw material is crushed, and keeping PCD value within a numerical range of +/-80-100 mV/Kg;

(3) excellent emulsifying performance, namely adopting w/o emulsifier; and an o/w emulsifier is adopted, and HLB is controlled to be 6.5-9.5.

In addition, according to the specific comprehensive practical situation of pulping and papermaking enterprises, the fiber defibering agent of the invention is required to have excellent stain resistance, anti-redeposition property, washing effect, hard water resistance and dispersibility for the waste paper raw materials with the whiteness base number (ISO) of pulping fiber of about 45.0%, L of 70.0, a of 0.07 and b of 6.00, and ensure wide practicability in the process of treating the waste paper raw materials.

In addition, the defibering agent of the present invention should have the following characteristics, which are adjusted by a small trial:

(1) the saponification value is controlled to be 150-210 mgKOH/g;

(2) permeability must be ensured to be greater than 70.0%;

(3) the HLB value is controlled to be in the range of 7.50-9.50;

(4) the PCD value of the antistatic property is ensured to reach +/-180-220 mV/Kg;

(5) the pH value must be controlled within the range of 8.5-9.5.

Especially, the key point of the technical problem to be solved by the invention is that the fiber fluffing agent not only has a relatively high saponification value, but also has super-strong permeability and antistatic property, and the hydrophilic-lipophilic value data in HLB is also adjusted.

Based on the above, the present invention has carried out a great deal of systematic research on the existing raw materials, and combines the research content to carry out self-making or improvement on part of the raw materials. The preparation method of the raw materials adopted in the examples is as follows:

(1) preparation of 5% aqueous sodium chloroacetate solution

1.0mol of chloroacetic acid and 1.0mol of sodium hydroxide (converted to 100% purity) were weighed and reacted in water twice as much as the reactants. The feeding method comprises the following steps: firstly, placing 2 times of water of reactants into a high-quality plastic container, firstly adding a certain amount of 1.0mol of NaOH, slowly stirring to uniformly dissolve the NaOH, and then slowly adding a certain amount of 1.0mol of chloroacetic acid and an aqueous solution of sodium hydroxide for reaction. The operation is as follows: chloroacetic acid was added slowly with slow stirring to form a solution of sodium chloroacetate. This reaction is exothermic. And when all chloroacetic acid is added, naturally raising the temperature of the reaction system to 90-100 ℃. When the reaction is finished, the temperature of the system begins to decrease; until the temperature is reduced to normal temperature, and then the mixture is diluted to 5.0 percent concentration by using clean water for standby.

If the pH value of the 5.0% sodium chloroacetate aqueous solution is less than 7.0, the pH value is regulated to 8.50-9.50 by adopting NaOH aqueous solution, and the mixture is placed, stored and observed.

(2) Preparation of Potassium nonylphenol polyoxyethylene (4/10) ether phosphate (NP (4/10) PK)

1.0mol (about 400 g) of nonylphenol polyoxyethylene (4) ether (NP-4), 1.0mol (about 640 g) of nonylphenol polyoxyethylene (10) ether (NP-10), 100 g of water, and 2.0 mol (about 275 g) of 70% phosphoric acid were weighed. Firstly, putting NP-4 and NP-10 into a 2000mL stainless steel container at one time according to a fixed quantity, then mixing water with a fixed quantity of 100 g and 275 g of phosphoric acid with a content of 70 percent, adding the mixture into the mixture of the NP-4 and the NP-10, and uniformly stirring the mixture; after reacting for 2.0 hours at normal temperature, gradually and slowly neutralizing with 5.0 mol (about 295.1 g) of potassium hydroxide with a purity of 95%; at this time, the system reacts in an explosive exothermic reaction. When the potassium hydroxide is added, the reaction temperature of the system is 130-160 ℃. Then covering and sealing the cover and naturally cooling the cover to the normal temperature; storing for later use. The chemical structural expression of the reaction principle can be written as follows:

the resulting product was nonylphenol polyoxyethylene (4/10) ether phosphate potassium salt (NP (4/10) PK). The product appearance was: the pulp has the advantages that the purity of the light yellow transparent thick body is more than 98.0 percent, the pH value is more than 7.50, the HLB is more than 8.0, the anti-fouling rate is more than 96.0 percent, the antistatic performance in the pulping process is +/-200-260 mV/Kg (calculated by electrostatic repulsion), the emulsifying dispersibility is 100.0 percent, and the bond force of various cationic high polymer (general name of stickies) functional groups adsorbed on the surface active functional groups of cellulose molecules of paper pulp is reduced by 50-70 percent; the ability to decompose the adhesive in a saturated state is 80-90% (at 80-90 ℃).

The product is a self-made material, and the cellulose is not sold in the market or reported in literature. The similar products in the market currently include different types of PK antistatic agents (namely potassium nonylphenol polyoxyethylene (10) phosphate) and antistatic agents P. These antistatic materials have been experimentally confirmed to fail to meet the requirements for use in the present invention.

The general molecular structure of the product can be represented as:

the reason why nonylphenol polyoxyethylene (4) ether NP-4 is used as a modifying material for potassium nonylphenol polyoxyethylene (10) ether phosphate is that nonylphenol polyoxyethylene (4) ether has excellent lipophilicity and can moderately reduce the hydrophilicity of nonylphenol polyoxyethylene (10) ether; the reduction range is up to more than 30-45%, and simultaneously, a proper emulsification and dispersion effect is achieved, and the HLB value can be adjusted to 8.0-9.50.

(3) Preparation of sodium nonylphenol polyoxyethylene (4) ether 12-alkylbenzene sulfonate

13.0Kg (about 32.0 mol) of nonylphenol polyoxyethylene (4) ether and 15.5Kg (about 43 mol) of 12-alkylbenzene sulfonic acid are accurately weighed, under the catalysis of 0.002% sulfuric acid, after the reaction is carried out for 2.0 hours at normal temperature, 9.5Kg (about 237.5 mol) of sodium hydroxide with the content of 99.0% is added and dissolved evenly in 180Kg of water (the concentration is 5.2 percent), and then the 5.2% sodium hydroxide aqueous solution is added into the reaction systems of the nonylphenol polyoxyethylene (4) ether and the 12-alkylbenzene sulfonic acid successively for neutralization and dilution; the product, sodium nonylphenol polyoxyethylene (4) ether 12-alkylbenzene sulfonate, was 22.5%. The 12-alkyl benzene sulfonic acid and the sodium hydroxide in the reaction system are required to be excessive.

The chemical structural expression of the reaction principle can be written as follows:

the number of reaction molecules in this reaction formula is: 1.0mol of nonylphenol polyoxyethylene (4) ether, 1.3mol of 12-alkylbenzenesulfonic acid, and 2.5mol of sodium hydroxide.

The quality indexes of the self-made product material are as follows: appearance, yellow brown translucent thick liquid; the pH was 11.0; the purity is 22.5-25.0%; HLB was 9.50; the permeability is > 90.0%. The self-made material belongs to a nonionic surfactant; its main role is to effectively adjust the HLB value, permeability and miscibility (i.e. interfacial activity) in the mixed system of the defibering agent to meet the needs.

(3) Compounding of ternary mixtures with soap

The compound material belongs to a middle adjusting material of the fiber fluffer and is not qualitatively explained. The material compounding principle is as follows: sodium nonylphenol polyoxyethylene (4) ether 12-alkylbenzenesulfonate: c (12/18) mixture of dibasic unsaturated fatty acid ethyl ester soaps: 40% potassium modified nonylphenol polyoxyethylene (4/10) ether phosphate 1.2:1.0: 0.67. The method has the advantages that the preparation process of the fiber fluffing agent is more convenient, the actual use effect is better, and the quality is more stable.

The three materials can not be fed separately one by one in the implementation process of the invention, and the three materials can be put into use after being mixed for about 7-15 days, but can be put into use immediately after being mixed, otherwise, the use effect is not good inevitably in the process of synthesizing the product of the invention, and the phenomenon of system layering or uneven mixing can be caused by carelessness; the reason is that reasonable explanation can not be given up to now, and the true principle is not found; however, this is true in practical use.

(4) Complex unsaturated fatty acid ethyl ester soap solution (i.e. C)₁₂/C₁₈Composite unsaturated fatty acid ethyl ester soap mixed liquor) preparation

(see application No. 201910117993.3 for details.)

Where the molecular chain of the unsaturated fatty acid contains 2C-C bonds, mostly 12 carbon atoms, and 1-COOH terminal functional group, such as coconut oil fatty acid and palm kernel oil fatty acid; the acid value and saponification value of the unsaturated fatty acid are 265-275 mgKOH/g and 257-265 mgKOH/g, so that the acid value and saponification value of the unsaturated fatty acid are relatively high. For unsaturated fatty acid with 18 carbon atoms in the molecular chain, 3C-C structural units and one-COOH, the number of the carbon atoms in the molecular chain of the unsaturated fatty acid is relatively large, the acid value of the unsaturated fatty acid is 205-215 mgKOH/g, and the saponification value is 200-210 mgKOH/g; the unsaturated fatty acids include cottonseed oil acid and rapeseed oil acid.

The total yield of the product is 660.0Kg, the pH value is 7.0-7.5, and the product can be put into use after being stored and kept still for 36.0 hours.

The second step is that: synthesis C₁₂/C₁₈Specific operation of composite unsaturated fatty acid polyoxyethylene (9) ether phosphate

660.0Kg of the reacted material is weighed, 69.0Kg (52.8 mol) of phosphoric acid with the content of 85.0 percent and 20.0Kg of water are added into the material, the mixture is placed into a 2000L stainless steel container, and the mixture is kept stand to react for 2.50 hours to obtain C₁₂/C₁₈The pH value of the heterogeneous material of the composite unsaturated fatty acid polyoxyethylene (9) ether phosphate is 2.0-3.0.

The third step: synthesis C₁₂/C₁₈Specific operation of composite unsaturated fatty acid polyoxyethylene (9) ether phosphate potassium salt

35.4Kg (600 mol) of KOH with the content of 95.0 percent is weighed and added into the materials one by one under the condition of slow stirring, and the system releases heat violently and looks like an explosion; after all of the KOH had been added, the vessel was emptiedCovering tightly, naturally cooling the material to normal temperature, and obtaining the product of the step C₁₂/C₁₈Compounding unsaturated fatty acid polyoxyethylene (9) ether phosphate potassium salt finished products; if a white precipitate at the bottom of the container is found to be potassium phosphate, the third step needs 12.0 hours from the reaction to the cooling. (see application No. 201910117993.3 for details.)

The self-made product is used as a composite antistatic agent, and the composite antistatic agent can show excellent comprehensive performance for treating any natural raw fiber raw material and any waste paper raw material; due to the variety of waste paper, the treatment difficulty of pulping is different; especially, the material has outstanding use effect on waste paper types which are difficult to treat, such as waste bill paper, beer label paper, tea filter paper and other waste paper mixed with fibers. Generally, the waste paper raw material contains a large amount of chemical components of various types of functional auxiliaries. Functional groups and functional groups contained in these chemical components, such as polyethylene group, polypropylene group, polybutadiene group, polyamide group, polyacrylonitrile group, and the like; the types of functional groups are: -OCOCH_2,,-CONH₂,-NH₂-NCO and the like; the functional groups combined with the functional groups of the high polymer are combined with the plant fibers to generate strong electrostatic attraction to be firmly adsorbed on the surfaces of the fibers, and after aging for a period of time, the high polymer has strong water resistance because the high polymer has the characteristics of oleophylicity and hydrophobicity; even under the action of mechanical force and hydraulic high speed, the fiber is not easy to untwin. The C12/18 unsaturated fatty acid part in the material has strong oleophylic, solvent-philic, saponification and washing performances; the polyoxyethylene (9) ether part has strong permeability and dispersibility besides oleophylic and hydrophilic properties; the potassium phosphate salt part has high reactivity but belongs to a non-polar combined group; the three are combined into one, and the material has a nonionic active group of a double electric layer, so that the material has strong electrostatic repulsion effect when preparing raw pulp or treating various waste paper pulps; the PCD value of the antistatic performance of the material is +/-190-320 mV/Kg. Apparently, the fluffing mechanism of the material in production practice is as follows: oleophilic natureHydrophilic → swelling → relaxing → pulping. This is a fundamental feature and unique aspect of this material.

(6) Fast-acting dissolution osmotic actives

From C₁₂/C₁₈Complex unsaturated fatty acid ethyl ester soap mixture and C₁₂/C₁₈The compound unsaturated fatty acid polyoxyethylene (9) ether phosphate potassium salt is prepared in a ratio of 1.0: 1.65. The proportion of the material in the feeding formula of the fiber fluffing agent is large, if the functional material variety is not used in the implementation process of the fiber fluffing agent, the efficacy is obviously reduced by more than 30.0 percent, and the storage period and the stability of the quality can not be ensured; this has been strongly demonstrated many times in large-scale industrial production practices; and is a kind of functional raw material which can not be avoided. (see application No. 201910117993.3 for details.)

(7) Composite solvent

The composite solvent is formed by mixing a C12/18 unsaturated fatty acid ethyl ester soap mixture and dimethyl phthalate, and the weight ratio is 9.0: 1.2. The composite solvent is mixed while adding the sodium chloroacetate aqueous solution, and the most outstanding advantages are that: the miscibility of the fiber fluffer system can be improved by 100 percent, the permeability is improved by more than 90 percent, the saponification value can still maintain the numerical range of 190mgKOH/g, the interface effect among the raw material components in the mixed system is reduced, and the HLB, the dissolving capacity and the decomposing capacity can be correspondingly improved and improved; meanwhile, the uniformity of the fiber fluffer system is improved and adjusted.

The production process flow of the fiber fluffing agent comprises the following steps:

the production process flow of the fiber fluffing agent mainly comprises two stages of material preparation and stirring and mixing. The preparation process comprises the preparation and the compounding of the self-product material, and also comprises the determination of the quantity of other materials required by the invention. The stirring and mixing process is to determine the variety and quantity of each material set in the formula and feed the materials in sequence under the condition of slowly stirring continuously until the materials are uniformly mixed, and the control method of the technological process is as follows:

feeding the required material (composition) varieties in sequence according to the properties (such as compatibility with solubility, permeability, antistatic property and the like) of the similar material varieties; operating under the normal temperature environment; the feeding operation mode is intermittent. And after the feeding is finished, adjusting the pH value of the system to be 9.50-10.50. The main control technical parameters are as follows: the permeability is 90.0% in 1.0 minute, the HLB is 8.90-9.50, and the PCD value of the antistatic performance is +/-190-230 mV/Kg.

The following are specific examples:

the fiber fluffing agent provided by the embodiment of the invention is primarily divided into three categories aiming at the types of waste paper used in the pulping and papermaking industries, namely deinked pulp waste paper which is easy to disintegrate, chemical pulp, chemimechanical pulp and mechanical pulp waste paper which are relatively difficult to disintegrate, and special type waste paper which is difficult to disintegrate; the waste paper usually contains a large amount of chemical fibers and special functional polymer adhesive substances. In general, any paper making enterprise can select waste paper raw materials which are relatively mixed for making the same finished paper type, and the waste paper raw materials cannot be selected one by one in the production process. Therefore, the defibering agent is defined herein as three synthetic formulation embodiments according to the characteristics of the three types of waste paper. As shown in table 2:

TABLE 2 Synthesis examples of three types of defibering agent feeding formulas

During preparation, the specific feeding sequence is as follows: 1 → 6 → 3 → 4 → 2 → 5 → 7, and the fiber fluffing agent with the corresponding type is obtained after uniform stirring and mixing.

Repeated experiments verify that the performance and functional index profiles of the three types of defibering agents are shown in table 3:

TABLE 3 Properties and functional profiles of three types of defibrinating agents

The physical and chemical properties of three types of fiber fluffers are as follows:

the three types of fiber fluffers are yellow to cream-yellow thick fluid, are easy to dissolve in water, and the aqueous solution is alkalescent; the emulsion is in a foggy state in water and can be rapidly dispersed; can be mutually soluble with most hydrophilic organic solvents and is insoluble in hydrophobic solvents such as benzene, dimethylbenzene, turpentine, substituted hydrocarbon and the like; has strong permeability, strong fluffiness, high activity and excellent antistatic and hard water resistance. The specific gravity (d20 ℃) is 0.988-0.998, and the thermal decomposition temperature is 180 ℃; belongs to a mixture nonionic surfactant, and the biodegradability can reach 90.0 percent; the HLB value is between 8.90 and 9.50; no CMC value; non-toxic, non-inflammable, non-explosive and non-corrosive.

The three-model feeding formula of the embodiment has strong practicability in the aspect of waste paper pulping. The actual use effect of the product synthesized by the three feeding formulas in the production process is as follows in sequence: SPO-01M > SPO-02M > SPO-03M. The use cost aspect is as follows in sequence: SPO-01M > SPO-02M > SPO-03M. Under the common condition, each pulping and papermaking enterprise selects one of three types of feeding formulas according to the cost, the type and the characteristics of waste paper raw materials, so that the requirement of the actual production process can be met.

SPo-01M: in the presence of NaOH, H₂O₂Under existing conditions, the method is mainly used for treating waste paper seeds which are difficult to break; comprises waste paper with various special purposes and waste paper containing chemical fiber components, and the dosage ratio is 0.5-1.5%.

SPo-02M: in the presence of NaOH, H₂O₂Under the existing conditions, the paper is mainly used for treating waste paper types which are difficult to disintegrate, and the waste paper mainly comprises regenerated decorative base paper, various paperboard, veneering paper waste paper and the like, wherein the wet strength of the waste paper is high (35-65%), and the waterproof performance of the waste paper is high. The dosage ratio is 0.5-1.0%.

SP-03M: in the presence of NaOH, H₂O₂The existing conditions are mainly used for treating common waste paper, deinked waste paper and the like which are commonly used. The dosage ratio is 0.2-0.3%.

Examples of formulations of these three types of defibering agents: can be accompanied by NaOH and H₂O₂Can be used in combination or independently under the existing condition; the product can be used under the condition of heating to 80-100 ℃ or under the condition of normal temperature; but the pulping time is different. The common characteristics of the three types of fiber fluffers are as follows: excellent functions of disintegration, stain resistance, static resistance, anti-redeposition, deinking and the like. According to the data shown in table 2 and table 3, the sequence of the effects of the three defibering agents is: SPo-01M is superior to SPo-02M, and SPo-02M is superior to SP-03M. In fact, in the practical application process, the variety of SP-03M is the most popular and most practical; because of its lowest cost of use.

Specific examples of applications are as follows:

the following examples all use the similar products (pulping enzymes) as comparison reference to measure the advantages and disadvantages of the using effect. Specific application examples are cited below:

application example one:

the waste paper raw material used by certain paper making enterprises is known to be: about 30 percent of chemical fiber waste paper, about 45 percent of banknote base paper waste paper edge and about 25 percent of stainless steel veneering waste paper. The three waste papers were mixed and found to have an average whiteness base of 75.0% (ISO), an L value of 89.76, a of 0.23 and b of 5.79. The types and the dosage ratios of the chemical auxiliary agents used in the pulping process are respectively as follows: 96% NaOH, 2.50%, 27.5% H₂O₂5.0 percent; the dosage of the pulping enzyme is equal to that of the SPo-01M of the invention, and the dosage is 1.0 percent. Controlling the pH value to be 11.0-11.5 in the pulping process; the crushed pulp concentration is about 15.0%; the pulping temperature is 100-120 ℃; the rotating speed of a spiral knife of the pulper is 330-360 revolutions per minute; the time for crushing was preliminarily set at 1.50 hours/time. The final results are shown in table 4:

TABLE 4 comparison of the effectiveness of the use of Spo-01M in the first application example with the pulping enzyme in the pulping process

The data in Table 4 show that under the same conditions, compared with the pulping enzyme, SPo-01M has the advantages that the defibering effect in the pulping process is more than 45.0 percent stronger, and the economic benefit is obviously and greatly improved.

Application example two:

the yield of a certain medium-sized paper making enterprise in Guangdong is about 500 tons/24 h; the produced finished paper is characterized in that the basis weight is 110-130 g/m²The imitation ox card wrapping paper; the pulper is a high-concentration pulper, the nominal volume is 15.0m3, the rotating speed of a pulping knife is 320-350 r/min, and the amount of waste paper which can be thrown in is 2000 kg/cylinder pulp; the crushed pulp concentration is 14.50%; the mixed waste paper is regenerated by all mechanical pulp with high wet strength, strong water resistance and more stickies; this waste paper is here difficult to meter and differentiate in proportion; the chemical auxiliary agent is 96 percent of NaOH, 1.50 percent; 27.5% H₂O₂2.0 percent, and controlling the pH value to be 9.5-10; the pulping temperature is normal temperature, and the pulping time is preliminarily set to be 0.8 h; under the same conditions, the same amount of pulping enzyme and SPo-02M product was added, and the results of the application are shown in table 5:

TABLE 5 comparison of the effect of SPo-02M and pulping enzyme on the treatment of mixed mechanical pulp broke in application example two

As can be seen from Table 5, the results of comparing the values of the two are still not on the same order of magnitude, and SPo-02M is much superior to the pulping enzyme.

Application example three:

the production ration of a certain large-scale paper making stock company in China is 45.0g/m²The daily output of the environment-friendly writing paper is 1700 tons/day; the waste paper raw materials are 40.0 percent of book and magazine paper and 60.0 percent of newsprint; the whiteness base number of the pulp sheet after the mixed waste paper is pulped is 54.50 percent. The company requires that the fiber fluffer not only has the efficiency of quick fluffing, but also can replace the deinking agent of excellent variety to achieve the best deinking effect; paired systemThe overall cost of the pulping process must be reduced. The pulping process conditions of the company are as follows: the pulping temperature is 100 ℃, the pulping time is 10.0 minutes, the pulping concentration is 30-35%, the pH value of paper pulp is 8.50-9.50 in the pulping process, and rotary drum type continuous pulping equipment is adopted. The quantification of the chemical raw materials added is: 30% NaOH solution, 2.0%; 27.5% H₂O_2，2.50 percent; na with Baume degree of 46 °₂SiO₃0.70 percent. Under the same condition, the same dosage of pulping enzyme, deinking agent and SPo-03M is added, and the dosage ratio is 0.2 percent respectively; the results of the series of processes of pulping → dilution → rough concentration → fine concentration → thermal dispersion → flotation are compared in the following table 6:

TABLE 6 comparison of the effectiveness of the pulping enzyme, deinking agent, and SPo-03M in flotation deinking

As can be seen from Table 6, under the same conditions, the treatment with SPo-03M can achieve better whiteness, hue, kowter degree, and higher yield, and also has better deinking effect.

The above application examples fully demonstrate that: the fiber fluffing agent of the invention can show excellent use effect for treating various waste paper raw materials; not only has strong ability of defibering waste paper fiber, but also has excellent effect of decomposing adhesive and deinking, and achieves the expected actual use effect.

As is clear from the first to third examples of industrial applications, compared with the technical characteristics of the existing pulping process, the inventors of the present invention have comprehensively and systematically summarized the key data provided by various pulping and papermaking enterprises using the defibering agent in the industrial operation process through a large number of production practice and scientific experimental results, and the data results of the detailed summary are shown in table 7:

TABLE 7 comparison of the comprehensive visual practical application effects of the biological enzyme, the deinking agent, the naphthalene sodium sulfonate and the fiber defibering agent

The data results in table 7 again verify the correctness of the technical measures and theoretical viewpoints that the active substances with saponification values synthesized by the composite unsaturated fatty acids provided by the inventors are adopted to inhibit various degradations caused by the use of the fibers, and the electrostatic repulsion effect between the fibers in the pulp disintegrating process is increased by using the materials with excellent antistatic performance, and the raw materials in the defibering agent are mutually cooperated and are aligned, so that the ideal effects of the data in table 7 can be realized. The results of the data in SP-03M of Table 7 are difficult to achieve if combined according to prior art and prior theoretical considerations, which indirectly embodies the advantages of the defiberizing agents of the present invention.

The environment-friendly condition of the fiber fluffer of the invention is as follows:

the fiber fluffer of the invention belongs to a series product, and has approximately same performance and function; but only the numerical values of various properties and functions are different. In the process of developing the fiber fluffing agent, the fiber fluffing agent not only has the properties and functions, but also aims to make the fiber fluffing agent meet the quality requirements and conditions of actual production. In the production process of the fiber defibering agent, noise interference, atmospheric pollution and waste liquid discharge are completely avoided; so-called 'three-waste pollution' is strictly controlled; even the water used for cleaning production sites and packages is strictly treated by measures such as circulation, sedimentation, filtration and the like. In addition, the unit using the defibering agent of the present invention is the pulping and papermaking enterprises, and since there are many papermaking enterprises, the variety of the produced finished paper and the variety of the waste paper raw material are different, and it is difficult to describe them one by one, the inventor can only briefly state the practical benefit of the environmental protection after using the defibering agent of the present invention in the pulping and papermaking process, as shown in table 8.

R represents a water treatment agent of biological enzyme, polyaluminium chloride (or aluminium sulfate) and cationic polyacrylamide;

other various pulping aids are: biological enzymes of green film, usa and japanese king de-inking agent.

The data in table 8 are the average values obtained by the inventors from samples of the wastewater collected at the wire water of the wet end of the papermaking after processing 56 waste papers. The data in table 8 show that the defibering agent of the present invention has obvious advantages in reducing environmental protection pressure and improving environmental protection quality. If two other types of products SPo-01M and SPo-02M of the defiberizing agent of the present invention are used in Table 8, they can be further improved or optimized by 25.0% and 35.0% respectively, as compared to the data in the column R + SP-03M in Table 8.

In conclusion, the fiber fluffing agent provided by the invention mostly adopts excessive NaOH and 27.5% H aiming at the waste paper types which are difficult to disintegrate at present₂O₂(or 22.5% NaClO); then pulping enzyme, naphthalene sodium sulfonate, sodium lignosulfonate and other pulping aids are added, and the mixture is treated by methods such as high-temperature causticization, oxidation, thermal dispersion and the like, and the treatment effect is not good enough, and according to the type, property and characteristic of functional papermaking auxiliary agent components contained in the waste paper and the principle of potential balance of positive and negative charges in the waste paper, the sodium chloroacetate, the soap-containing ternary compound mixture, the composite unsaturated fatty acid polyoxyethylene (9) ether phosphate potassium salt and the quick-acting soluble osmotic active agent are compatible, the theoretical characteristics of nonionic electrostatic repulsion, activation, permeation, defibering and the like of all raw materials are comprehensively utilized and are mutually cooperated, so that the prepared fiber defibering agent has permeability, dirt resistance, antistatic property, emulsifying decomposability and saponifying property required by treating various waste paper difficult to disintegrate, has excellent fiber defibering capacity and can be used for treating the waste paper difficult to disintegrate in the pulping and papermaking industry.The paper raw material or the natural plant fiber raw material shortens the pulping time, improves the paper pulp yield and the fiber quality, and improves the pulping process efficiency and the environmental protection benefit.

Compared with the prior art, the fiber fluffing agent has the most prominent differences and advantages that: on the basis of the full performance and functions of quick-acting dissolution and permeation active substances, a strong antistatic agent, namely potassium nonylphenol polyoxyethylene (4/10) ether phosphate, and sodium nonylphenol polyoxyethylene (4) ether dodecylbenzene sulfonate are adopted, and meanwhile, a soap-type ternary compound mixture is compatible by means of parting compounding; the electrostatic repulsion effect among various waste paper fibers is enhanced in a strong composite antistatic way; the soap-containing ternary complex mixture and the quick-acting dissolved osmotic active substance are used for improving the osmotic defibering efficiency of a pulping system and inhibiting the degradation of cellulose molecules in fibers; sodium nonylphenol polyoxyethylene (4) ether dodecylbenzene sulfonate and 5.0% sodium chloroacetate aqueous solution are used to improve the permeability and dispersibility in the process of defibering waste paper. The ideal effects as shown in tables 4, 5, 6, 7 and 8 can be achieved by the synergistic effect of the above materials; rather than indiscriminately relying on and using excess amounts of other pulping aids such as NaOH, bio-enzymes, etc., resulting in decreased fiber yield and mechanical strength, as well as other quality problems of unknown origin.

In addition, the raw materials of the formula of the fiber fluffer, such as 5.0% sodium chloroacetate aqueous solution, potassium nonylphenol polyoxyethylene (4/10) ether phosphate, soap-containing ternary compound mixture and sodium nonylphenol polyoxyethylene (4) ether dodecylbenzene sulfonate, can be put into production in large batch according to the market demand and can meet the use requirements of users, the production periods are 4.0 hours, 14.0 hours, 5.0 hours and 6.0 hours respectively, and the production period is short; the synthesis of the fiber fluffer only needs to be mixed, and the operation is carried out at normal temperature; one batch of products can be produced within 1.0 hour, and the products are also ensured to be non-toxic, non-irritant and non-corrosive, thereby being beneficial to improving the environmental protection conditions and quality. Therefore, the fiber fluffing agent has a very good application prospect, is easy to popularize, and has practical significance and practical value for comprehensive utilization of natural resources, renewable resources and recycling economy. As shown in the application examples I to III, the fiber fluffing agent of the invention is produced in a large scale in an industrialized mode, and the product is sold on the market and is practically applied, so that certain economic benefit is obtained.
