CAS No.: ********4 Molecular Formula: C2H8O7P2 Molecular weight:
**6.*2 Structural Formula: Properties: HEDP is an organophosphoric
acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions
to form stable chelating ***** 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. Specification: items index Appearance Colorless or light

max - Usage: 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, ***** 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. Package and Storage: HEDP
liquid: Normally In **0kg net Plastic Drum, IBC drum can also be
used as required HEDP solid: *5kg inner liner polyethylene (PE)
bag, outer plastic woven bag, or confirmed by clients. Storage for
ten months in room shady and dry place. Safety Protection: Acidity,
Avoid contact with eye and skin, once contacted, flush with
water.  Keywords: HEDP
