HEDP water treatment chemical
Hydroxy Ethylidene-1,1-Diphosphonic Acid
CAS No. 2809-21-4
Molecular Formula: C2H8O7P2 Molecular weight: 206.02
Properties:
1.HEDP is an organophosphoric acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds and dissolve the oxidized materials on these metals’ surfaces.
2.HEDP shows excellent scale and corrosion inhibition effects under temperature 250ºC. HEDP has good chemical stability under high pH value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions.
3.When built together with other water treatment chemicals, it shows good synergistic effects.
PS: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.
