• Detailed Description:

  Cas No. :3794-83-0(4-Na) Properties:
  HEDPNa4 is the sodium salt of
  HEDP, HEDPNa4 is an good scale
  inhibitor for calcium carbonate,
  it can be used in low pressure
  boiler water system, circulating
  water system, industrial and
  municipal cleaning water system
  and swimming pool.
  The solid HEDPNa4 is white
  powder, soluble in water, easily
  deliquescence, suitable for use
  in winter and freezing districts.
  It is a kind of organophorphonic
  acid scale and corrosion
  inhibitor, can form stable
  complex with Fe, Cu and Zn ions,
  it can dissolve the oxides on
  metal surface, it has good scale
  and corrosion inhibition effect
  under 250℃.
  HEDPNa4 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, HEDPNa4 is used as
  detergent for metal and nonmetal.
  In dyeing industry, HEDPNa4 is
  used as peroxide stabilizer and
  dye-fixing agent; In non-cyanide
  electroplating, HEDPNa4 is used
  as chelating agent.
