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 yana nuna kyakkyawan ma'auni da tasirin hana lalata a ƙarƙashin zafin jiki na 250 ℃. HEDP yana da kyakkyawan kwanciyar hankali na sinadarai a ƙarƙashin ƙimar pH mai girma, mai wuyar gurɓata ruwa, kuma yana da wuya a ruɓe ƙarƙashin haske na yau da kullun da yanayin zafi. Its acid/alkali da chlorine oxidation haƙuri sun fi na sauran organophosphoric acid (gishiri). 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.

A m hali na 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.

Amfani:

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 1-10mg/L is preferred as scale inhibitor, 10-50mg/L as corrosion inhibitor, and 1000-2000mg/L as detergent. Usually, HEDP is used together with polycarboxylic acid.
