Ⅱ. Performance and use
Copper corrosion inhibitor mercaptobenzothiazole can be used as copper corrosion inhibitor in circulating cooling water system. The corrosion inhibition of copper corrosion inhibitor mercaptobenzothiazole mainly depends on the chemisorption of active copper atoms or copper ions on the surface of copper. Or further chelation to form a layer of dense and firm protective film, copper equipment to get good protection, the usage amount is generally 4mg/L, copper corrosion inhibitor mercapto benzothiazole can also be used as plasticizer, acid copper plating photometric agent.
Ⅲ. Packaging and storage
Copper corrosion inhibitor mercaptobenzothiazole is packaged in plastic drum, each drum is 25kg or according to customer's requirement. Store in a cool, dry place for six months. A small amount of precipitation at the bottom is normal after a long time storage. Shake well and use.
Ⅳ. Safety protection
Copper corrosion inhibitor mercaptobenzothiazole is alkaline, pay attention to labor protection during operation, should avoid contact with the skin, eyes, etc., after contact with a lot of water rinse.
