Eigenskippen:

HEDP is in organophosphoric acid corrosie inhibitor. It kin chelate mei Fe, Cu, en Zn ioanen te foarmjen stabile chelating compounds.It kin oplosse de oxidized materialen op dizze metalen oerflakken. HEDP toant treflike skaal en corrosie remming effekten ûnder temperatuer 250 ℃. HEDP hat goede gemyske stabiliteit ûnder hege pH-wearde, dreech te hydrolyzed, en dreech te ûntbinen ûnder gewoane ljocht en waarmte omstannichheden. Syn soer / alkali en chlor oksidaasje tolerânsje binne better as dy fan oare organofosphoric soeren (sâlt). 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.

De fêste steat fan 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.

Gebrûk:

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.
