Applications of montmorillonite for increasing bacteriostasis effect in paper making process

Abstract

The invention discloses an application of the bacteriostatic and rotproof functions of turface to the paper-making technique. The turface and disinfectant for the paper-making technique are mixed evenly and the mixture is put into a paper-making system; or the turface is added in the condition of using the disinfectant in the paper-making technique. The optimized usage amount is 0.5 to 5 kilograms of turface with a purity quotient of 95 percent per ton of paper. The turface can be mixed with various disinfectants to use and can be made into particles with grain diameter within 100 microns by other accessories and used by separating from an antibacterial agent. The turface has good adsorptive action can absorb the antibacterial agent and the microorganisms around the turface particles, thereby improving the concentration of the disinfectant around microorganisms and achieving the disinfecting effect with high concentration and high efficiency. On the condition that the bacterial content reaches the mark, the usage amount of the antibacterial agent is reduced evidently.

Description

technical field [0001] The invention belongs to the technical field of light industry papermaking, and relates to the application of a mineral in the papermaking process, in particular, the application of montmorillonite in the papermaking process to enhance the antibacterial effect. Background technique [0002] The papermaking system of the papermaking process is rich in nutrients, and has a temperature (25-40°C) 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 t...

AI Technical Summary

Problems solved by technology

[0005] Bactericides are usually added after the sludge is formed. On the one hand, the number of microorganisms is large, and the amount of fungicides required is large; Play a role so that the microorganisms in the pulp are not well controlled

Some sludge resides in the dead corner of the papermaking equipment, which cannot be killed by fungicides, and usually needs to be shut down for cleaning, which not only affects production, but also increases production costs
