Abstract
The invention aims to provide an efficient compounded neutral bactericide and a preparation method thereof. The efficient compounded neutral bactericide comprises 10%-30% of deionized water, 30%-50% of alcohols, 18%-26% of quaternary ammonium compounds, 12%-20% of sulfone bichloride and 0.5%-2.5% of a nonionic surfactant. The efficient compounded neutral bactericide can be used as a compound bactericide for an industrial recycling cooling water system and a paper-making white water system, has the characteristics of broad spectrum, high efficiency and safety, is a neutral bactericide and has no corrosion to equipment. With the use of the bactericide, mild scale formed by microorganisms in the circulating water system and paper-making white water can be effectively controlled and removed.
Description
Technical field
The present invention relates to a kind of bactericide, particularly a kind of composite sterilizing agent for industrial circulating cooling water system or mthod of white water from paper making system, more particularly, the invention particularly relates to a kind of based on composite sterilizing agent of two chlorine sulfone and preparation method thereof.
Background technology
In recirculating cooling water system, the formation of organic attachment is primarily of caused by the growing of microorganism.In cooling water, microorganism generally refers to bacterium and algae.In fresh water, bacterium and algae are all less, but in cycle water, due to the enrichment method of nutrient, the rising of water temperature and illumination create the condition of breeding rapidly to bacterium and algae.Microorganism can become medium at the mucus of growing up and release in reproductive process, foundry loam in water is sticked in cooling-water duct together with plant debris etc., prevent the main method producing organic attachment in condenser copper tube from being the microorganism killed in cooling water, make it lose to be attached to the ability on tube wall.Kill method of microorganism and mainly add bactericide.
Along with the development of modern paper technology, adopt advanced high-speed paper machine and closed plain boiled water circulating technology, improve production efficiency, improve product quality, decrease consumption and the sewage discharge of clear water simultaneously; But the High circulation of plain boiled water system, a large amount of waste paper recycling and chemical assistant filler, a large amount of organic residue material is constantly accumulated in plain boiled water system, add harmful microbe growth and breeding, form the microorganism viscosity mud of thickness, sedimentation or be attached in paper machine equipment wall, the normal operation that impact is produced; Or be suspended in slurry, adhere on paper, cause the paper defects such as hole, spot, variable color, reduce product quality, cause serious sediments obstacle (" rotten slurry " problem).Once there is these problems, just must stop producing, discharge contaminated plain boiled water, and after stop cleaning and again can continue to produce after injected clear water.In current solution paper-making process, the most effectual way of microorganism problem adds bactericide in mthod of white water from paper making.
Summary of the invention
The object of the present invention is to provide the agent of a kind of efficient compound neutral sterilization.Can be used for the compound disinfectant of industrial circulating cooling water system and mthod of white water from paper making system, there is the feature of broad-spectrum high efficacy safety, be a kind of neutral sterilization agent, equipment is not corroded.Use bactericide of the present invention can effectively control and remove circulating water to unify the soft dirt that microorganism is formed in mthod of white water from paper making.
The object of the present invention is to provide the preparation method of above-mentioned bactericide, the method is simple to operate, and reaction condition is gentle, is easy to suitability for industrialized production.
