Pwopriyete:

HEDP se yon inibitè korozyon asid organofosfò. Li ka chelate ak Fe, Cu, ak iyon Zn pou fòme konpoze ki estab ki chelating.Li ka fonn materyèl oksidize yo sou sifas metal sa yo. HEDP montre echèl ekselan ak efè anpèchman korozyon anba tanperati 250 ℃. HEDP gen bon estabilite chimik anba valè pH segondè, difisil yo dwe idrolize, ak difisil yo dwe dekonpoze anba limyè òdinè ak kondisyon chalè. Tolerans oksidasyon asid/alkali ak klò li yo pi bon pase lòt asid organofosfò (sèl). 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.

Eta solid la nan 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.

Itilizasyon:

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.

Sekirite ak pwoteksyon:

HEDP se asid. Peye atansyon sou pwoteksyon travay pandan operasyon an. Evite kontak ak je ak po. Si li pwojeksyon sou kò a, rense imedyatman ak anpil dlo.
