Properties:HEDP is an organophosphoric 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 temperature **0℃. HEDP has
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). HEDP can react with
metal ions in water system to form hexa-element chelating complex,
with calcium ion in particular. Therefore, HEDP has 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. Because of 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 system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, HEDP is used as detergent for metal and nonmetal. In dyeing industry, HEDP is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP is used as chelating agent. The dosage of ***0mg/L is preferred as scale inhibitor, ****0mg/L as corrosion inhibitor, and ********0mg/L as detergent. Usually, HEDP is used together with polycarboxylic acid.
