Disodium Of 1 Hydroxy Ethylidene Diphosphonic Acid Hedp Na2 - China

CAS No.

7417-83-7 CubleK2012 Dequest: 2016BD Molecular

Formula: C2H6O7P2Na2 Molecular weight: 250 Properties: HEDP Na2 is an

organophosphonic acid corrosion inhibitor, it can chelate with Fe, Cu,

and Zn ions, it can dissolve the oxidized materials, it has good scale

and corrosion inhibition effects even under 250 centigrade degrees, it

is stable under high pH value, not easy to be hydrolyzed, not easy to

be decomposed under normal light and heat condition, its acid/alkaline

and chloride oxidation tolerance are better than that of other

organophosphonic acids.

HEDP?Na2 can form six-ring chelating compounds

with metal ions in water system, Ca2+ in particular.

HEDP Na2 has good

scale inhibition effects and obvious dissolution threshold effects.

When used with other Water Treatment Chemicals, the synergistic effects

is better.

6.0 Usage: HEDP Na2 is widely used in circulating cool water system,

medium and low pressure boiler, oil field water pipelines as scale and

corrosion inhibitor in fields such as electric power, chemical

industry, metallurgy, fertilizer, etc.

In light woven industry,

HEDP?Na2 is used as detergent for metal and nonmetal.

In dyeing

industry, HEDP Na2 is used as peroxide stabilizer and dye-fixing agent;

In non-cyanide electroplating, HEDP?Na2 is used as chelating agent.
