Performance and use
Dodecyl dimethyl benzyl ammonium chloride is a cationic surfactant, a non-oxidizing bactericide, with broad-spectrum, high-efficiency bactericidal and algae-killing ability, and can effectively control the growth of bacteria and algae and slime in water , And has a good slime peeling effect, a certain degree of dispersion and penetration, and a certain degree of oil removal, deodorization and corrosion inhibition.
Dodecyl dimethyl benzyl ammonium chloride has low toxicity, no cumulative toxicity, and is easily soluble in water, and is not affected by water hardness. Therefore, it is widely used in circulating cooling water in petroleum, chemical, electric power, textile and other industries In the system, it is used to control the growth of bacteria and algae in the circulating cooling water system, and has special effects on killing sulfate reducing bacteria.
Dodecyl dimethyl benzyl ammonium chloride can be used as a bactericidal and antifungal agent, softener, antistatic agent, emulsifier, and conditioner in the textile printing and dyeing industry.
How to use
Dodecyl dimethyl benzyl ammonium chloride is used as a bactericidal and algaecide, the general dosage is 50-100mg/L; as a slime stripping agent, the dosage is 200-300mg/L, and an appropriate amount can be added when needed Silicone defoamer. Dodecyl dimethyl benzyl ammonium chloride can be used in conjunction with other fungicides, such as isothiazolinone, glutaraldehyde, dithiocyanomethane, etc., can have a synergistic effect, but cannot be used with chlorophenols The medicine is used together. After dosing dodecyl dimethyl benzyl ammonium chloride, the filth appears in the circulating water due to stripping, it should be filtered or removed in time to avoid deposition after the foam disappears. Do not mix dodecyl dimethyl benzyl ammonium chloride with anionic surfactants such as polyacrylic acid and hydrolyzed polymamarine.
Packaging and storage
Dodecyl dimethyl benzyl ammonium chloride is packed in plastic barrels, 25kg or 200 kg per barrel; 80% content is 190kg/barrel. Dodecyl dimethyl benzyl ammonium chloride is stored in a cool and ventilated place indoors, and the storage period is two years.
Safety and protection
Dodecyl dimethyl benzyl ammonium chloride has a slight almond odor and does not cause obvious skin irritation. When it comes in contact with the skin, just rinse with water.
