Technical Field

The invention relates to a wood board, in particular to a hollow wood board capable of absorbing formaldehyde and an internal ventilation structure thereof.

Background

The formaldehyde volatilization point is at 19 ℃, and the higher the temperature is, the more violent the volatilization is; the other point is that the incubation period is as long as 3-15 years, the two characteristics enable the formaldehyde to become 'stubborn molecules' of air pollution, when heating is carried out in winter, the temperature of most of consumers at home can be maintained at about 20 ℃, so that the formaldehyde is volatilized, a powerful space is created, the volatilization at 19 ℃ is over three times, the higher the temperature is, the more intensely the formaldehyde volatilization point is known, the higher the temperature is, the more intensely the formaldehyde is, the temperature is increased once, the concentration is increased by 0.4 time, and particularly, the higher the temperature is increased and released more intensely in spring and summer, and the concentration can exceed 3 times of normal concentration.

According to living of different types of people, formaldehyde can be volatilized at different time to live, and the method comprises the following steps:

1. adults

After the new house is finished being decorated, the house is preferably placed for 3 months, because some harmful substances remained in the decoration are not volatilized, a certain time is needed, if the conditions allow, an inspection company can be requested to carry out formaldehyde detection on the new house, and the house can be checked after the house reaches the check-in standard.

2. Pregnant woman

If a pregnant woman is in home, the pregnant woman is preferably kept for more than 4 months, because the fetus is not stable in the early pregnancy, and harmful substances such as formaldehyde can influence the health of the pregnant woman and the fetus, so that the pregnant woman can be better to live at a later time.

3. Babies

If a baby is in a family, the baby is preferably placed for more than 6 months, because the organ development of the newborn is not perfect enough, the immunity is weak, and the newborn is easily damaged by harmful objects such as formaldehyde, so that the symptoms such as growth retardation and deformity of the baby are caused.

Formaldehyde has strong irritation to eye, nose and throat mucous membrane, and the most common symptoms are eye irritation and headache, severe allergic dermatitis and asthma, and can inhibit cell function because formaldehyde can react with protein to generate nitrogen methine compound to make protein in cell coagulate and denature.

In addition, formaldehyde can react with ionic chloride in the air to generate dichloromethyl ether, which is a carcinogenic substance, and formaldehyde can be adsorbed and enriched by high specific surface materials in a room and released again when the temperature in the room rises, so that the pollution effect is intensified. China 'indoor air quality Standard' stipulates that the limit value of formaldehyde in indoor air of second type civil building engineering is 0.10mg/m, and the limit value of formaldehyde in indoor air of first type civil building engineering is 0.08mg/m for carrying out heavy planting. One type of civil construction includes: residential buildings, hospitals, classrooms of schools, old buildings and kindergartens.

Formaldehyde of the formula HCHO or CH₂O, molecular weight 30.03, also known as formil. Is colorless, odorless, and has stimulating effect on human eyes and nose. Gas relative density 1.067 (air = 1) and liquid density 0.815g/cm (20 ℃).

Melting point-92 deg.C, boiling point-19.5 deg.C. Is easily soluble in water and ethanol. Aqueous solutions, up to 55% strength, usually 40%, are known as formalin (formalin) which is a colorless liquid with an irritating odor.

Has strong reducibility, and particularly has stronger reducibility in alkaline solution. Can be combusted, and the steam and air form explosive mixture with explosion limit of 7-73% (volume). The ignition point is about 300 ℃.

Can be prepared by dehydrogenation or oxidation of methanol under the catalysis of metals such as silver, copper and the like, and can also be separated from hydrocarbon oxidation products. Can be used as raw materials of phenolic resin, urea-formaldehyde resin, vinylon, urotropine, pentaerythritol, dye, pesticide, disinfectant and the like.

The industrial formaldehyde solution generally contains 37% of formaldehyde and 15% of methanol, and is used as a polymerization inhibitor and has a boiling point of 101 ℃.

The main hazard of formaldehyde is manifested by irritation of the skin mucosa. When the formaldehyde reaches a certain concentration indoors, people feel uncomfortable.

Formaldehyde concentrations greater than 0.08mg/m may cause redness, itching of the eye, discomfort or pain in the throat, hoarseness, sneezing, chest distress, asthma, dermatitis, etc. The newly decorated room has high formaldehyde content and is the main cause of many diseases.

In 2017, 10 and 27, in a carcinogen list published by the international cancer research institution of the world health organization, formaldehyde is put in a carcinogen list.

The best methods for eliminating formaldehyde today;

1. the photocatalyst can generate a photocatalytic reaction similar to photosynthesis under the irradiation of ultraviolet light to generate free hydroxyl and active oxygen with extremely strong oxidizing power, and has a very strong photooxidation-reduction function.

2. The organic compound and partial inorganic matter are oxidized and decomposed, the cell membrane of bacteria and the protein of immobilized virus can be destroyed, the bacteria can be killed, the organic pollutants can be decomposed, and the organic pollutants are decomposed into pollution-free water and carbon dioxide, so that the air purifying agent has extremely strong functions of sterilization, deodorization, mildew prevention, pollution prevention, self cleaning and air purification.

3. The photocatalyst has good degradation and killing effects on middle and low molecular unstable compounds and most of germs, and comprises formaldehyde.

Since formaldehyde is dissolved in water and then changed into formalin solution, and high-concentration formalin has toxicity and pungent odor, even though the purification device of the present invention continuously performs the function of purifying formaldehyde and has low formaldehyde content, the purification device needs to be arranged outdoors for safety.
