Detailed Description

The principles and features of this invention are described below in conjunction with embodiments, which are included to explain the invention and not to limit the scope of the invention.

Wyoming-type bentonite: a carrier for inactivating a key component of pathogenic bacteria. The wyoming bentonite has good interlayer structure and carrier space, and can fully meet the occurrence and filling requirements of various key components. The mixing amount of the purified bentonite is less than 5 percent, the space of the carrier is small, the component occurrence condition is not met, the sterilizing agent can not normally play a role, the variety of inactivated bacteria is few, the effect is poor, if the mixing amount of the bentonite is more than 10 percent, the carrier is too much, the dispersion of the surfactant to the sterilizing component is not facilitated, the homogenization of the sterilizing agent is not facilitated, and the industrial popularization and the cost rise are obvious.

Active lime powder: the sterilizing agent ecological reconstruction system alkali matrix is used for controlling the alkaline environment of the whole sterilizing agent modification system. After activation treatment, the influence of the alkali-aggregate reaction of the system can be reduced, and the self lattice depression degree of the combined material can be greatly improved, thereby being beneficial to improving the strength of the later-stage modification and sterilization effect; the mixing amount is higher than 50%, the pH value index of a modification system can be influenced, the salinization phenomenon in the germ inactivation process can be caused, the ecological reconstruction of organic matters is not facilitated, and the mixing amount is lower than 40%, so that the plastic index modification capability of the germ inactivation system can be reduced, and the engineered and large-scale operation of a sterilizing agent is not facilitated.

Benzalkonium chloride: benzalkonium chloride belongs to a non-oxidizing bactericide, has broad-spectrum and high-efficiency sterilization and algae killing capability, can effectively control the propagation of bacteria and algae and the growth of slime, has good slime stripping effect and certain dispersion and permeation effects, and simultaneously has certain deoiling and deodorizing capability and corrosion inhibition effect. The component has a strong effect in the later effect of the sterilizing agent, and the sterilizing effect in a later solution system is not ideal if the mixing amount of the component is too small, and the cost is too high if the mixing amount is too large.

The sterilization auxiliary agent comprises polymeric ferrous sulfate and polyvidone: the two are used in a matching way, the matching ratio is 1:1, and the key components for pathogen inactivation in a solid or semisolid system are mainly used for improving the mineralization of a sterilizing agent material, reducing the interface reaction heat of each material and reducing the dry shrinkage index of the material, and are also providers of system sterilizing components. The content of the two is less than 10 percent, the mineralization effect is poor, the nucleation speed of system crystallization is slow, and the germ inactivation effect is poor; the mixing dosage of the two is higher than 30%, the adsorption bridge chain of the system and even the crystallization channel are easy to be filled and blocked, the influence on the water retention index and the bacterial inactivation index is larger, and the production cost of the sterilizing agent is greatly increased.

The dispersant comprises calcium lignosulfonate and OP-X: the two are surfactants which mainly play a role in dispersing, can reduce the surface tension and promote the dispersing effect of various components in a system. The mixing ratio of the two is 1:3, the surface tension is not obviously reduced when the mixing amount is too low, the viscosity in the system is increased when the mixing amount is too high, the uniformity index of material bonding is influenced, and the cost is obviously increased.
