• Functions and Applications
  • Bactericidal and Algicidal: As a highly efficient non - oxidizing bactericide, it has a broad - spectrum killing effect on bacteria and algae in water. It can effectively control the reproduction of bacteria and algae and the growth of slime in the circulating cooling water system, and has a special killing effect on sulfate - reducing bacteria. It is widely used in the circulating cooling water systems of petroleum, chemical, electric power, textile and other industries.
  • Slime Stripping: It has a good slime stripping effect, which can make the slime fall off from the equipment surface, facilitating cleaning.
  • Textile and Dyeing Auxiliary: In the textile and dyeing industry, it is used as a bactericidal and mildew - proof agent, softener, antistatic agent, emulsifier and conditioner. It can make the fibers fluffy, prevent static electricity generation, and can also be used as a leveling agent to make the dyeing more uniform.
  • Disinfection and Antisepsis: In the medical field, it can be prepared into an aqueous solution of a certain concentration for the disinfection of skin and surgical instruments, and can also be used for the washing and disinfection of wound infections. It is also used for the disinfection of livestock pens, grain warehouses, silkworm rooms, as well as the breeding places and utensils of cash crops. It can also be used as a preservative for paste, gelatin and photographic film.
  • Other Uses: It can be used as a surfactant in products such as detergents, cleaners and lubricants, and is used in personal care, agricultural and industrial cleaning and other fields. It can also be used to prepare hand - washing liquids and other products.
• Usage Method
  • Bactericidal and Algicidal Agent: In the circulating water system, the general recommended dosing amount is 50 - 100mg/L, which can be adjusted appropriately according to the water quality and the degree of bacterial and algal pollution.
  • Slime Stripping Agent: For severe slime pollution, the usage amount can be increased to 200 - 300mg/L. If necessary, an appropriate amount of silicone - based defoamer can be added to improve the effect.
  • Combined Use: It can be used in combination with a variety of bactericides, such as isothiazolinone, glutaraldehyde, dithiocyanomethane, etc., to achieve a better bactericidal effect. However, it should not be used simultaneously with chlorophenol - based agents to avoid adverse reactions.
• Safety, Packaging and Storage
  • Packaging: Packed in plastic barrels with good sealing performance. The net weight of each barrel is usually 25kg or 200kg, and different specifications can also be customized according to customer requirements.
  • Storage: It should be stored in a cool and ventilated indoor place, avoiding direct sunlight and high - temperature environment. Under normal storage conditions, the shelf life can reach twelve months.
• Safety Protection Measures
  • Although it has no obvious irritating effect on the skin, personal protection should still be paid attention to during the use process to avoid direct contact with the skin and eyes. In case of accidental contact, rinse immediately with a large amount of clean water.
  • Avoid mixing with anionic surfactants such as polyacrylic acid and hydrolyzed poly 马来酸 (hydrolyzed polymaleic acid), so as to prevent chemical reactions that may affect the use effect or cause potential safety hazards.
