Abstract

The invention relates to a preparation method of an antibacterial cleaning paper. The preparation method comprises the following steps: preparing a sterilizing solution from a ketone control agent, allowing the sterilizing solution to flow into a flow aid, performing uniform mixing, allowing the obtained mixture to flow into a starch pulp, and performing uniform mixing to prepare a sterilized paper pulp; preparing sterilizing white water from an ammonium control agent, a hypochlorite solution and deionized water; allowing the sterilizing white water to respectively flow into the water chute ofa surface white water barrel, the white water chute of a core layer white water barrel, the bottom white water bucket, a spray starch storage tank and a warm water tanks; and producing antibacterialcleaning paper through a conventional papermaking process. The above bactericides enter all the operations of the papermaking process in a flowing manner to make bacteria killed sufficiently, and thesterilizing white water can effectively flow into all parts of a high-bacteria system to achieve efficient sterilization. The bactericides such as the ketone control agent, the ammonium control agent,the hypochlorite are adopted, so various microorganisms can be killed, and the bacterial content of the system is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for preparing antibacterial cleaning paper. Background technique [0002] With the development of the paper industry and the increasing shortage of available resources in the world, many paper manufacturers have begun to recycle waste paper and papermaking white water to reduce raw material costs and environmental pollution, which inevitably brings a large number of microorganisms into papermaking. in the production system. Due to the existence of a large number of microorganisms in the papermaking production system, sludge is easily formed in the equipment and pipelines through which pulp and white water flow, and sludge will bring great harm to the production process and product quality. [0003] The pulp is heated by steam, the microorganisms are killed by high temperature, and there are less microorganisms in the preparation system. However, because it contains...
