Pasipatan:

HEDP mangrupa inhibitor korosi asam organofosfat. Bisa chelate kalawan Fe, Cu, sarta ion Zn pikeun ngabentuk stabil chelating compounds.It bisa ngaleyurkeun bahan dioksidasi on surfaces logam ieu '. HEDP nembongkeun skala alus teuing jeung épék inhibisi korosi dina suhu 250 ℃. HEDP mibanda stabilitas kimiawi alus dina nilai pH tinggi, teuas pikeun dihidrolisis, sarta teuas pikeun decomposed dina lampu biasa jeung kaayaan panas. Toleransi oksidasi asam/alkali sareng klorin langkung saé tibatan asam organofosfat (uyah). 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.

Kaayaan padet tina 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.

Pamakéan:

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.
