Disodium Salt of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid USES

HEDP·2Na is a kind of organic phosphonic acid scale inhibitor and corrosion inhibitor, which can form stable complexes with iron, copper, zinc and other metal ions, and can dissolve oxides on the metal surface. It can still play a good corrosion and scale inhibition effect at 250℃, and is still very stable at high pH, not easy to hydrolysis, and not easy to decompose under general photothermal conditions. Acid and alkali resistance, chlorine oxidation resistance is better than other organic phosphonic acid (salt). It can form six ring chelates with metal ions in water, especially calcium ions, so it has a good scale inhibition effect and an obvious solution-limiting effect. When combined with other water treatment agents, it shows an ideal synergistic effect. Suitable for metal cleaning, metal treatment and metal ion control applications.
