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 shows excellent scale and corrosion inhibition
effects under temperature **0℃. HEDP 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 chlorine oxidation tolerance are better than that
of other organophosphoric 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 antiscale and
visible threshold effects. When built together with other water
treatment chemicals, it shows good synergistic effects.
The solid state of 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
