Problems solved by technology

[0003] At present, most of the slime stripping agents used in domestic circulating cooling water systems are cationic surfactants, mainly dodecyl dimethyl benzyl ammonium chloride (1227), tetradecyl dimethyl benzyl chloride Ammonium (1427), etc., have a good stripping effect, but they may have an impact on other water treatment chemicals during use. At the same time, with the passage of time and the advancement of technology, the lack of gas also appears, and bacteria are prone to it. Drug resistance, large dosage, high cost, and many foams during use, which are not easy to be removed, etc., which will affect the circulating cooling water system

Abstract

The invention belongs to the technical field of chemical water treatment and in particular relates to a slime sterilizing and stripping agent applied to industrial circulating water. The slime sterilizing and stripping agent is prepared from the following components in parts by weight: 2.0-2.5 parts of a KF-508 biological dispersant, 2.0-2.5 parts of a penetrant, 15.0-16.0 parts of diquarternary ammonium salt and 80-80.5 parts of water, wherein the KF-508 biological dispersant is a sold macromolecule organic matter formed by compounding of dimethyl amine methylene sodium diphosphate which is produced by Urumqi Science Development Fine Chemical Industry Limited Company; the penetrant is a dodecyl benzyl dimethyl ammonium chloride cationic surfactant; the diquarternary ammonium salt is bis-phenyl imino-dialkyl phenpropyl-dodecyl dimethyl ammonium chloride. The slime sterilizing and stripping agent is mainly used for treating process of the industrial circulating water.

Description

technical field [0001] The invention belongs to the technical field of chemical water treatment, in particular to a sterilizing and stripping agent for slime in industrial circulating water. Background technique [0002] In the process of industrial circulating water treatment, corrosion, scaling and microbial problems are often encountered. With the improvement of water treatment technology, most of the corrosion and scaling problems have been better solved, but the problem of biological slime in the system is still prominent. The composition of biological slime includes various complex microorganisms such as algae, bacteria, fungi and inorganic and organic impurities. These microorganisms are bound together by the adhesive of the outer cell membrane, making them difficult to be affected by environmental factors other than biological slime (such as fungicides, scale inhibitors and dispersants or other water treatment chemicals). Therefore, slime Microorganisms in the medi...
