Guryaha:

HEDP is an organophosphoric acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds.It can dissolve the oxidized materials on these metals’ surfaces. HEDP waxay muujinaysaa miisaan aad u fiican iyo saamaynta xakamaynta daxalka ee heerkulka 250 ℃. HEDP Waxay leedahay xasillooni kiimiko oo wanaagsan oo hoos timaada qiimaha pH ee sarreeya, way adag tahay in la nadiifiyo, wayna adag tahay in lagu burburiyo iftiinka caadiga ah iyo xaaladaha kulaylka. Asiidhkeeda/alkaliyada iyo dulqaadka oksaydhka koloriinta ayaa ka fiican kan acids organophosphoric kale (milix). 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.

Xaaladda adag ee 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.

Isticmaalka:

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.

Badbaadada iyo ilaalinta:

HEDP waa acidic. U fiirso ilaalinta shaqada inta lagu jiro hawlgalka. Ka fogow taabashada indhaha iyo maqaarka. Haddii ay ku firdhiso jidhka, isla markiiba ku raaci biyo badan.
