1. Performance and use:

Copper corrosion inhibitor MBT (Na) can be used as a copper corrosion inhibitor in circulating cooling water systems. The corrosion inhibition of copper corrosion inhibitor MBT (Na) mainly relies on chemical adsorption with active copper atoms or copper ions on the surface of metal copper; or chelation occurs to form a dense and firm protective film, so that copper equipment is well protected. The usage is generally 4 mg/L. MBT (Na) can also be used as a plasticizer, acid copper plating brightness agent, etc.
