HEDP he mea hoʻopaneʻe ʻino ka waika organophosphoric. Hiki iā ia ke hoʻoheheʻe me nā ion Fe, Cu, a me Zn e hana i nā pūhui chelating paʻa. HEDP hōʻike i ka pālākiō maikaʻi a me nā hopena inhibition corrosion ma lalo o ka mahana 250 ℃. HEDP He paʻa kemika maikaʻi ma lalo o ka waiwai pH kiʻekiʻe, paʻakikī ke hoʻoheheʻe ʻia, a paʻakikī hoʻi e decomposed ma lalo o nā kūlana māmā a me ka wela. ʻOi aku ka maikaʻi o kona ʻakika/alkali a me ka chlorine oxidation tolerance ma mua o nā ʻakika organophosphoric ʻē aʻe (paʻakai). 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.

ʻO ke kūlana paʻa o 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.

Hoʻohana:

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.
