What is HEDP ?
HEDP(Etidronic acid) is an organic scale and corrosion inhibitor, which can form stable complexes with various metal ions such as iron, copper and zinc, and can dissolve the oxides on the metal surface. It can still play a good role in corrosion and scale inhibition at 250 °C, and it is still very stable at high pH value, not easy to be hydrolyzed, and not easy to decompose under general photothermal conditions. It has good scale inhibition effect and obvious solubility limit effect. When used in combination with other water treatment agents, it shows an ideal synergistic effect. It is a high-purity product and is suitable for severe cold areas in winter; it is especially suitable for cleaning agents and daily chemical additives in the electronic industry.
