HEDP is an organophosphonic acid scale and corrosion inhibitor, which can form a stable complex with iron, copper, zinc and other metal ions, and can dissolve oxides on the metal surface. It can still play a good role in corrosion inhibition and scale inhibition at 250 °C, and is still very stable at high pH, not easy to hydrolyze, and not easy to decompose under general light and heat conditions. It can form a six-ring chelate with metal ions in water, especially calcium ions, so it has a good scale inhibition effect and obvious dissolution limit effect, and shows an ideal synergistic effect when used in combination with other water treatment agents. HEDP solids are high-purity products suitable for use in harsh winter areas, especially for cleaning agents and daily chemical additives in the electronics industry.
