HEDP ke organophosphoric acid corrosion inhibitor. E ka chelate ka li-ion tsa Fe, Cu, le Zn ho theha metsoako e tsitsitseng ea chelating. E ka qhala lisebelisoa tse nang le oxidized holim'a litšepe tsena. HEDP e bonts'a litlamorao tse ntle haholo tsa ho thibela kutu le ho thibela ho bola tlas'a mocheso oa 250 ℃. HEDP e na le botsitso bo botle ba lik'hemik'hale tlas'a boleng bo phahameng ba pH, e thata ho etsoa ka hydrolyzed, 'me e thata ho bola tlas'a khanya e tloaelehileng le maemo a mocheso. Mamello ea eona ea asiti / alkali le chlorine oxidation e betere ho feta ea li-organophosphoric acid tse ling (letsoai). 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.

Boemo bo tiileng ba 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.

Tšebeliso:

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.
