Properties:
HEDPis 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.Itshows excellent scale and corrosion inhibition effects under temperature **0℃.
HEDPhas 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 chlorine oxidation tolerance are better than that of other organophosphoric acids (salt).
 HEDPcan react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore,ithas good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects.
SolidHEDPis crystal powder, suitable for usage in winter and freezing districts. Due to its high purity, it can be used as cleaning agent in electronic fields and as additives in daily chemicals.
