Scaling-corrosion inhibitor STD-800
Performance and use
STD-800 is a compound of organic phosphonic acid, polycarboxylic acid, carbon steel corrosion inhibitor and copper corrosion inhibitor. It has a good chelating and dispersing effect on calcium carbonate, calcium sulfate, calcium phosphate, etc. in water, and has a good corrosion inhibition effect on carbon steel and copper.
STD-800 is mainly used for corrosion and scale inhibition in circulating cooling water systems, such as power plants, chemical plants, petrochemicals, steel and other circulating cooling water systems. It has good corrosion inhibition effect and strong scale inhibition ability.
