Application
It can still play a good corrosion and scale inhibition effect at 250°C, and is still very stable at high pH, not easy to hydrolyze, and hard to decompose under general light and heat conditions. It has better acid and alkali resistance and chlorine oxidation resistance than other organic phosphonic acids (salts). It can form 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, it shows an ideal synergistic effect . HEDP solid is a high-purity product, suitable for winter in severe cold areas; especially suitable for cleaning agents and daily chemical additives in the electronics industry.
