Applications of montmorillonite for bacteriostasis and corrosion protection in paper making process

Abstract

The invention discloses an application of the bacteriostatic and rotproof functions of turface to the paper-making technique. According to the standard that every ton of paper adopts 0.5 to 20 kilograms of turface with a purity quotient of 95 percent, the turface is directly added into a paper-making system. If the turface with a purity quotient less than 95 percent, the usage amount of turface is increased correspondingly. The optimized usage amount is 0.5 to 5 kilograms of turface per ton of paper. The good expanding performance and the dispersivity of the turface ensure that compositions inside the paper pulp is scattered evenly and microorganisms are scattered inside the paper pulp; the turface has good adsorptive action and can absorb most of the microorganisms which are adhered on the fibers and are discharged out of the system as the paper-making process; therefore, the concentration of the bacteria in the paper-making system is minimized, thereby achieving the bacteriostatic effect. Meanwhile, the turface can also absorb various paper-making additives, organic nutriments and fine fibers which are discharged out of the system as the paper sheet, thereby reducing the white water concentration and damaging the condition bacteria live by, achieving the bacteriostatic effect and reducing the possibility of forming slime pulp.

Description

technical field [0001] The invention belongs to the technical field of papermaking in light industry, and relates to the application of a mineral in the papermaking process, in particular to the application of montmorillonite in the antibacterial and anticorrosion of the papermaking process. Background technique [0002] The papermaking system of the papermaking process is rich in nutrients, and has a temperature and humidity suitable for the growth and reproduction of microorganisms, especially the neutral papermaking system is more suitable for the growth and reproduction of microorganisms. The wide use of various chemical additives for papermaking, such as starch, is more conducive to the growth and reproduction of microorganisms, so that viscous sludge will be formed on the inner wall surface of each tank, pulp inlet and circulation pipeline during the papermaking process. It is composed of microfibers, resins, fillers and various sediments coagulated with each other thr...

If the bactericidal spectrum is not wide enough, the growth and reproduction of some microorganisms cannot be controlled

There are many times of use, and the method is cumbersome. It is necessary to adjust the input site, usage amount and number of times of fungicide according to the specific conditions of saprophyllum generation. Often, the sterilization fails due to insufficient dosage, or excessive dosage leads to waste and pollutes water resources.
