Product Description

Isothiazolinones CAS 26172-55-4 Water Purification Chemicals




Isothiazolinone is a kind of excellent water treatment agent with good miscibility. It can be miscible with various corrosion inhibitors, scale inhibitors and dispersants such as chlorine, most anionic, cationic and non-ionic surfactants. The commodities on the market are usually a mixture of 5-chloro-2-methyl-4-isothiazoline-3-one (CMI) and 2-methyl-4-isothiazoline-3-one (MI), and metal nitrite will also be added Or metal nitrate, improve stability and prevent decomposition. The mechanism of isothiazolinone is to kill bacteria by breaking the bond between bacteria and algae protein. After contacting with microorganisms, it can quickly and irreversibly inhibit their growth, which leads to the death of microbial cells. For common bacteria (sulfate reducing bacteria, sludge forming bacteria), fungi (iron oxide bacteria, mold), etc , yeast) and algae have strong inhibition and killing effects. It has the characteristics of high killing efficiency, good degradation, no residue, safe operation, good compatibility, strong stability and low cost. At high dosage, it has significant effect on biological slime stripping. At present, it has been widely used in iron and steel smelting, oilfield water injection, thermal power generation, paper making, oil refining, chemical industry, light textile, industrial cleaning, pesticide, cutting oil-water coating, daily chemical industry, ink, dye, leather and other fields.

It is used to treat industrial circulating water and has the function of sterilization and algaecide. It is a general antiseptic and can effectively kill algae, bacteria and fungi. The active agent can be widely used in industrial cooling water, oil field tank water, paper industry, pipeline, coating, oil chemical Book paint, rubber, cosmetics, photographic film and washing products industries. It is easy to be mixed in all kinds of formulas with a wide range of pH use. After diluting the use concentration, it is easy to be biodegraded into non-toxic and non polluting substances
