| Use | HEDP • Na is an organic phosphonic acid scale and corrosion inhibitor, which can form stable complexes with iron, copper, zinc and other metal ions, and can dissolve the oxides on the metal surface. At 250 deg C can still play a good corrosion and scale inhibition, high pH is still very stable, not easy to hydrolysis, general light and heat conditions are not easy to decompose. Acid and alkali resistance, chlorine oxidation resistance than other organic phosphonic acid (salt) good. It can form a six ring chelate with metal ions in water, especially calcium ions, so it has good scale inhibition effect and obvious solubility limit effect. When used in combination with other water treatment agents, show the ideal synergistic effect. HEDP • Na is the most suitable scale inhibitor and detergent for acidic formulations, HEDP • Na is hydroxy-ethylidene diphosphonic acid |

| use | HEDP • Na is an organic phosphonic acid scale and corrosion inhibitor, which can form stable complexes with iron, copper, zinc and other metal ions and can dissolve oxides on metal surfaces. It can still play a good role in corrosion and scale inhibition at 250 ℃, is still stable at high pH, is not easy to hydrolyze, and is not easy to decompose under general photothermal conditions. Acid and alkali resistance and chlorine oxidation resistance are better than other organic phosphonic acids (salts). It can form a six-ring chelate with metal ions in water, especially calcium ions, so it has a good scale inhibition effect and an obvious solution limit effect. When combined with other water treatment agents, it shows ideal Synergistic effect. HEDP • Na is the most suitable scale inhibitor and detergent for acidic formula. HEDP • Na is hydroxyethylenediphosphonic acid |
