BIT85 Usage

1. BIT is the main industrial sterilization, antiseptic, and anti-enzyme agent. It has a prominent inhibitory effect on the growth of molds, algae and other microorganisms in organic media, and can solve the mold, fermentation, deterioration, demulsification, and hair growth of organic products caused by microorganisms. A series of problems, such as odor, are widely used in sterilization, marine antifouling and other fields.

2. BIT is widely used in latex products, water-soluble resins, coatings (latex paint), acrylics, and polymers in developed countries. Polyamine products, photographic lotion, papermaking, ink, leather, lubricants and other products. However, the environmental behavior and ecological toxicity of isothiazolinone compounds have attracted people’s attention.

3. At present, domestic organic chemical wastewater treatment methods mainly include adsorption, liquid membrane extraction, reverse osmosis, electrodialysis, air stripping, ultrafiltration, etc. Because the adsorption method does not introduce new pollutants, has low energy consumption, and can separate and enrich organics from wastewater, and realize waste recycling, it is considered to be the best feasible technology to adsorb toxic and harmful organics from water. 4. In recent years, the use of chemical modification to synthesize composite functional resins containing functional groups has been used in the control of organic poisons.
