HEDP is used as scale and corrosion inhibition in circulating cool water systems, oil fields, and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc. In the light-weaved industry, HEDP is used as a detergent for metal and non-metal. In the dyeing industry, HEDP is used as a peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP is used as the chelating agent. Buy HEDP Solution Online. The dosage of 1-10mg/L is preferred as a scale inhibitor, 10-50mg/L as a corrosion inhibitor, and 1000-2000mg/L as a detergent. Usually, HEDP is used together with polycarboxylic acid. HEDP solution Corrosion inhibitor.

PROPERTIES

HEDP is an organophosphorus acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds. It can dissolve the oxidized materials on these metals’ surfaces. HEDP shows excellent scale and corrosion inhibition effects under temperatures of 250℃. HEDP has good chemical stability under high pH values, is hard to be hydrolyzed, and is hard to be decomposed under ordinary light and heat conditions. It is acid/alkali and chlorine oxidation tolerance are better than that of other organophosphorus acids (salt). HEDP can react with metal ions in the water system to form a Hexa-element chelating complex, with calcium ions in particular. Therefore, HEDP has good anti-scale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects. HEDP solution Corrosion inhibitor, Buy HEDP Solution Online.
