Therefore, it is widely used in circulating cooling water systems in industries such as petroleum, chemical, power, and textile to control the growth of bacteria and algae in the circulating cooling water system, and has the ability to kill sulfate reducing bacteria. 1227 can be used as an antifungal and softening agent, anti-static agent, emulsifier, conditioner, etc. in the textile printing and dyeing industry.

CIT/MIT is mainly composed of 5-chloro-2-methyl-4-isothiazoline-3-one (CMI) and 2-methyl-4-isothiazoline-3-one (MI). Isothiazolinone exerts its bactericidal effect by breaking the bond with algal proteins. After contact with microorganisms, isothiazolidone can rapidly and irreversibly inhibit their growth, leading to the death of microbial cells. Therefore, it has a strong inhibitory and bactericidal effect on common bacteria, algae, etc. High killing efficiency, good biodegradability, no residue generation, safe operation, good compatibility, strong stability, and low usage cost. Can be miscible with chlorine and most anionic, cationic, and non-ionic surfactants. At high doses, isothiazolidone has a significant effect on the removal of biological sludge. Isothiazolinone is a broad-spectrum, low toxicity, and non oxidizing biocide. Widely used in industries such as oil fields, papermaking, pesticides, cutting oils, leather, inks, dyes, and leather making.

It will not spoil or burn when stored below 120 ℃.

Strong chlorine essence, easily soluble in water, has the characteristics of being fast, broad-spectrum, and safe, and has extremely strong killing effects. At 10mg/L, the rate reaches 99%. The pH change has little impact on the effect, so it is particularly suitable as a biocide in the circulating water of fertilizer plants; It can completely replace chlorine gas and non oxidizing biocides, making it very economical. Has extremely strong bleaching properties. Stable in nature and convenient to use. Widely used in civil health, animal husbandry and plant protection, fabric bleaching, wool anti shrink, rubber chlorination, organic synthesis industry, etc.

DT-301 composite agent is composed of various quaternary ammonium salts and dialkylammonium chloride. It can quickly ionize into cationic active groups in water, firmly bind with negative charges on microbial cell walls, destroy cell activity, kill algae, and has better effects than quaternary ammonium salt products. Its killing effect is effective on various aerobic and anaerobic conditions. It can quickly penetrate into the clay layer and has a strong stripping and cleaning effect on biological clay. The applicable pH range is wide, and it is also effective under alkaline conditions. Used for algae killing treatment in various industrial circulating cooling water and wastewater treatment systems. Alternating use with oxidizing biocides, adding 1-2 times a month. Impact dosing, with the use concentration of 100 〜 150mg/l, will produce foam, which can be eliminated by adding an appropriate amount of defoamer.

DT-302 composite algal killer is a combination of quaternary ammonium salt amine and isothiazolinone. It has the characteristics of broad-spectrum, low toxicity, fast and long-lasting efficacy, and strong penetration. It can quickly penetrate into the clay layer and has a strong stripping and cleaning effect on biological clay. The applicable pH range is wide. Used for algae killing treatment in various industrial circulating cooling water and wastewater treatment systems. Add 2-4 times per month. Impact dosing, using a concentration of 80-150mg/l.

DT-303 clay stripping agent, composed of quaternary ammonium salts and penetrating agents. It can quickly penetrate into the clay layer and has a strong stripping and cleaning effect on biological clay. The applicable pH range is wide, and it is also effective under alkaline conditions. Has characteristics such as broad spectrum, fast efficacy, etc. Used for cleaning, peeling, and treating sticky sludge in various industrial circulating cooling water, wastewater treatment systems, etc. Impact dosing, with the use concentration of 100 〜 200 mg/l, will produce foam, which can be eliminated by adding an appropriate amount of defoamer.
