Product Description

Product Description

 

HEDP (similar to Dequest 2010) can chelate with Fe, Cu, Al, Zn etc. metal ions and form stable chelating compounds and dissolve the oxidized materials on metals' surfaces. It is soluble with water, shows excellent scale and corrosion inhibition effects under temperature 200°C and has good chemical stability under high pH value, hard to be hydrolyzed , and hard to be decomposed under ordinary light and heat conditions. Its acid/alkali and chlorin oxidation tolerance are better than that of other organophosphorus acids (salt). HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP has good antiscalant and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.The crystal powder of HEDP with high content, 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.

Applicatrion

2: In oil field and low-pressure boilers: as scale and corrosion inhibitor.
3: In light woven industry: as detergent for metal and nonmetal.
4: Dyeing: as peroxide stabilizer and dye-fixing agent.
5: In non-cyanide electroplating: as chelating agent.
6: RO system: as scale inhibitor.
