HEDP (Hydroxy Ethylene Di Phosphonic Acid)

Additional Details

We are offering a wide range of HEDP (Hydroxy Ethylene Di Phosphonic Acid) that is an organophosphoric acid corrosion inhibitor. To form stable chelating compounds, it can chelate with Fe, Cu, and Zn ions. It can also dissolve the oxidized material on the metal surfaces. The HEDP offered by us shows excellent scale and corrosion inhibition effects under temperature 250. It is appreciated by the clients for good chemical stability under high pH value, hard to be hydrolyzed, hard to be decomposed under ordinary light and heat conditions. Further, following are the technical specifications of our range of HEDP: Its acid & alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt) To form hexa-element chelating complex, with calcium ion in particular, it can react with metal ions in water system It also has good antiscale and visible threshold effects If built together with water treatment chemicals, it shows good synergistic effects The solid state of HEDP is crystal powder that is perfect for usage in winter and freezing districts Can be used as cleaning agent in electronic fields Can be used as additives in daily chemical. Usage: As scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer Used as detergent for metal and nonmetal in light woven industry. Used as peroxide stabilizer and dye-fixing agent in dyeing industry Used as chelating agent in non-cyanide electroplating The dosage of 1-10mg/L is preferred as scale inhibitor 10-50mg/L as corrosion inhibitor 1000-2000mg/L as detergent Used together with polycarboxylic acid
