HEDP

HEDP, ATMP, DTPMP, PBTC are used as scale inhibitor, deflocculant, sequestrant,
water stabilizer in water treatment, pipeline,
HEDPNa is an organophosphonic acid corrosion inhibitor, it can chelate with Fe, Cu, and Zn ions. HEDPNa can dissolve the oxidized materials, it has good scale and corrosion inhibition effects even under 250, 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 organophosph-onic acids. HEDPNa can form six-ring chelating compounds with metal ions in water system, Ca2+ in particular. HEDPNa has good scale inhibition effects and obvious dissolution threshold effects. When used with other Water Treatment Chemicals, the synergistic effects is better.
HEDPNa is suitable for acidic scale inhibitor and detergent, can be used for metal surface treatment. .
