Structural formula
Ⅰ. Performance and use
1227 is a cationic surfactant, is a non-oxidizing fungicide, has a broad spectrum, high efficiency of killing bacteria and algae, can effectively control the reproduction of bacteria and algae in the water and mud growth, and has a good mud stripping effect and a certain degree of dispersion, permeability, at the same time has a certain oil, deodorization and corrosion inhibition.
1227 small toxicity, no cumulative toxicity, and soluble in water, not affected by water hardness, so it is widely used in the circulation cooling water system of petroleum, chemical, electric power, textile and other industries, to control the circulation cooling water system bacterial algae breeding, to kill sulfate reducing bacteria has a special effect.
1227 can be used as the textile printing and dyeing industry of bactericidal mildew agent and softener, antistatic agent, emulsifier, conditioner.

Ⅲ. Method of use
1227 was used as bactericidal algicidal agent, and the dosage was generally 50-100mg/L. As a clay stripping agent, the usage is 200-300mg/L, when needed, can be added with an appropriate amount of silicone defoaming agent. 1227 can be used together with other fungicides, such as isothiazolinone, glutaraldehyde, dithiocyanomethane, etc., can have synergistic effect, but can not be used together with chlorophenol agents. After the addition of 1227, the sewage in the circulating water due to stripping should be filtered out or removed in time, so as to avoid the deposition after the foam disappears.
1227should not be mixed with anionic surfactants such as polyacrylic acid and hydrolyzed polyma.
Ⅳ. Packaging and storage
1227 packed in plastic drums of 25kg or 200kg each; The content of 80% is 190kg/ drum. Store in a cool and ventilated place for one year.
Ⅴ. Safety and protection
1227slightly almond flavor, no obvious irritation to the skin, contact with the skin, rinse with water.
