Njirimara:

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 Na-egosi ọmarịcha ọnụ ọgụgụ na mmetụta mgbochi corrosion n'okpuru okpomọkụ 250 ℃. HEDP nwere ezigbo nkwụsi ike nke kemịkalụ n'okpuru uru pH dị elu, siri ike ka ọ bụrụ hydrolyzed, na-esikwa ike imebi n'okpuru ọkụ nkịtị na ọnọdụ okpomọkụ. Ya acid/alkali na chlorine oxidation ndidi dị mma karịa nke ndị ọzọ organophosphoric acid (nnu). 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.

Ọnọdụ siri ike nke 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.

Ojiji:

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.
