Product description

Hydroxy Ethylidene-1, 1-Diphosphonic acid (HEDP)

CAS number: 2809-21-4

Active content (HEDP): 58.0-62.0%

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 250

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

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
