HEDP. Na2 is an organic phosphonic acid corrosion inhibitor, which can chelate with Fe, Cu and Zn ions, dissolve oxidizing substances, has a good scale and corrosion inhibition effect even at 250 °C, is stable at high pH, is not easy to hydrolyze, is not easy to decompose under normal photothermal conditions, and its acid/alkaline and chloride oxidation resistance is better than that of other organic phosphonic acids. In the aqueous system, Heddp Na2 can form hexacyclic chelate with metal ions, especially Ca2+. HEDP. Na2 has a good scale inhibition effect and an obvious dissolution threshold effect. When used in combination with other water treatment agents, the synergistic effect is better.
