*0% HEDP*****-Corrosion Inhibitor
Definition:
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.

Application:
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 industry, metallurgy, fertilizer, etc.. In
light woven industry, HEDP is used as detergent for metal and
nonmetal. In dyeing industry, HEDP is used as peroxide stabilizer
and dye-fixing agent; In non-cyanide electroplating, HEDP is used
as chelating agent. The dosage of ***0mg/L is preferred as scale
inhibitor, ****0mg/L as corrosion inhibitor, and ********0mg/L as
detergent. Usually, HEDP is used together with polycarboxylic
acid.
