  1, Properties
  HEDP is an organophosphoric acid
  corrosion inhibitor. It can
  chelate with Fe, Cu, and Zn etc.
  metal ions and form stable
  complex compound. It can dissolve
  the oxidized materials on these
  metals’ surfaces. Under 250℃
  HEDP shows excellent scale and
  corrosion inhibition ability.
  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 of HEDP is high purity
  product, suitable for using in
  winter and freezing districts. it
  is quite suitable for using as
  cleaning agent in electronic
  fields and as additives in daily
  chemicals.
  HEDP Application range&using
  method
  HEDP is widely used in the in
  circulating cool water system of
  electric power, chemical
  industry, metallurgy, fertilizer,
  etc. and widely used as a scale
  and corrosion inhibitor of low-
  pressure boilers, field
  waterflood, oil pipeline.
  In light&textile 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 1-10mg/L is
  preferred as scale inhibitor, 10-
  50mg/L as corrosion inhibitor,
  and 1000-2000mg/L as detergent.
  Usually, HEDP is used together
  with polycarboxylic acid.
