Papermaking sterilization agent

Abstract

The invention discloses a papermaking sterilization agent, which belongs to the technical field of papermaking industry. According to the technical scheme, the papermaking sterilization agent is composed of the following raw materials in parts by weight: 30-100 parts of 2,2-dibromo-3-cyano-acetamide, 10-50 parts of halogenated hydantoin, 8-22 parts of deionized water, 1-5 parts of acid, 5-12 parts of quaternary ammonium salt, 3-15 parts of organic bromide, 3-9 parts of magnesium nitrate, 3-9 parts of magnesium chloride, 1-6 parts of 5-chloro-2-methyl-isothiazolin-3-ketone and 10-20 parts of dodecyl dimethyl benzyl ammonium chloride. Compared with the prior art, the papermaking sterilization agent disclosed by the invention can be applied to a circulating cooling water system, has excellent sterilization and algae removal performance, and can effectively control slime to maintain the cleanness of the circulating cooling water system so as to ensure few impurities of paper and reduce paper defects. Moreover, the papermaking sterilization agent disclosed by the invention is free of resistance to drugs and is low in corrosion on equipment.

Description

technical field [0001] The invention relates to the technical field of papermaking industry, in particular to a bactericide for papermaking. Background technique [0002] With the development of society, people pay more and more attention to environmental protection. The research and development of paper-making fungicides used in the paper industry should also pay attention to environmental protection. The organic mercury and organic zinc fungicides used in the past have high bactericidal effects. , but highly toxic; another example is that chlorophenols also have a certain bactericidal ability, but they also have certain toxicity, which greatly limits their application. Instead, it should be a fungicide with high efficiency, low toxicity and good biodegradability. Each fungicide has specific effects, but it also has many defects. For example, some fungicides are only effective for bacteria, but not very effective for fungi. Good control effects, and some are just the oppos...
