Biocide for pipeline cleaning, and preparation method thereof

Abstract

The invention relates to a biocide for pipeline cleaning, and a preparation method thereof, wherein the biocide comprises the following raw materials by weight: 20-30 parts of 2,2'-dihydroxy-5,5'-dichlorophenylmethane, 10-20 parts of 2,2-dibromo-3-carbamoylacetonitrile, 5-10 parts of zinc dialkyl dithiophosphate, 5-10 parts of methylene bisstearamide, 1-3 parts of 3,7-dimethyl-2,6-octadiene nitrile, 10-15 parts of boric acid diglyceride sodium monostearate, and 200-300 parts of deionized water. According to the present invention, the biocide can form the protection film on the metal surface, such that the catalytic oxidation effect of the metal can be eliminated, and the surface corrosion and the surface wear on the metal can be prevented; the biocide can reduce the friction between the polymer molecular chains, can improve the lubricity among various raw materials, can reduce the reaction time, and can improve the sterilization and algae-killing effect; and the biocide has the mild odor, can make the treated pipeline maintain the lemon aroma, can label the treated pipeline in the odor manner so as to avoid the multiple treatments within a short time, and can improve the management efficiency and reduce the use cost.

Description

technical field [0001] The invention belongs to the field of water pollution treatment, in particular to a biocide for pipeline cleaning and a preparation method thereof. Background technique [0002] There are a large number of microorganisms in the cooling water. These microorganisms are generated and reproduced on the pipe wall of the cooling water equipment, which not only increases the frictional resistance of the water flow, causes the blockage of the pipe, but also seriously reduces the heat transfer efficiency of the heat exchanger. Causes dangerous pitting to perforate pipe. In order to control the production of microorganisms and the harm they cause, biocides are generally used to kill and inhibit the growth and reproduction of microorganisms. At present, the existing biocides have a single function and have no ability to protect and repair the deep layers of the pipeline; the reaction time is long and the flow speed is slow; the existence time after sterilization...

Problems solved by technology

At present, the existing biocides have a single function, and have no ability to protect and repair the deep layers of the pipeline; the reaction time is long, and the flow speed is slow; the existence time after sterilization is determined, which is likely to cause multiple operations in a short period of time and increase costs
