Detailed Description
Properties :
HEDP is an organophosphoric acid corrosion inhibitor. It functions to chelate with Fe, Cu, and Zn ions to form stable chelating compounds. It can dissolve the oxidized materials on these metals’ surfaces. It shows excellent scale and corrosion inhibition effects under temperature 250℃. It has a good chemical stability under high Ph value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. Its acid/alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids (salt). It can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore. It has a good antiscale and visible threshold effects. When built together with other water treatment chemicals. It shows good synergistic effects.
The solid state of HEDP is crystal powder, suitable for usage in winter and freezing districts due to its high purity. It can be used as cleaning agent in electronic fields and as additives in daily chemicals.
Usage :
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 light woven industry. It is used as detergent for metal and nonmetal. In dyeing industry. It is used as peroxide stabilizer and dye-fixing agent; in non-cyanide electroplating. It is used as chelating agent. A dosage of 1-10 mg/L is preferred as scale inhibitor, 10-50 mg/L as corrosion inhibitor, and 1000-2000 mg/L as detergent. Usually, HEDP is used together with polycarboxylic acid.
