Related Product Features:
  • HEDP is an organophosphoric acid corrosion inhibitor with excellent scale inhibition under temperatures up to 250°C.
  • It forms stable chelating compounds with Fe, Cu, and Zn ions, dissolving oxidized materials on metal surfaces.
  • Highly stable under high pH values, resistant to hydrolysis, and difficult to decompose under light and heat.
  • Superior acid/alkali and chlorine oxidation tolerance compared to other organophosphoric acids.
  • Effective in circulating cool water systems, oil fields, and low-pressure boilers.
  • Used in light woven industries as a detergent for metals and non-metals.
  • Acts as a peroxide stabilizer and dye-fixing agent in the dyeing industry.
  • Available in 250kg plastic drums or IBC drums, with a shelf life of ten months when stored properly.
Faqs:
  • What are the main functions of HEDP?
    HEDP is primarily used as a scale and corrosion inhibitor. It also serves as a detergent, peroxide stabilizer, dye-fixing agent, and chelating agent in various industries.
  • What is the recommended dosage of HEDP?
    The recommended dosage is 1-10mg/L as a scale inhibitor, 10-50mg/L as a corrosion inhibitor, and 1000-2000mg/L as a detergent.
  • How should HEDP be stored?
    HEDP should be stored in a shady, dry place for up to ten months to maintain its effectiveness.
