What is HEDP Na?
HEDP Na is an organic phosphonic acid scale 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 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 light and heat conditions. Acid and alkali resistance and chlorine oxidation resistance are better than other organic phosphonic acids (salts). It can form six-ring chelates with metal ions in water, especially calcium ions, so it has good scale inhibition effect and obvious tolerance effect. When used in combination with other water treatment agents, it shows ideal synergy effect.

What is HEDP Na used for?
Antiscalant: It can effectively inhibit the crystallization and deposition of calcium and magnesium ions in water, and prevent the formation of scale.
Corrosion inhibitor: It has good corrosion inhibition performance on steel, copper, aluminum and other metals, which can prolong the service life of equipment.
Dispersant: It can effectively disperse suspended solids and sludge in water to prevent them from depositing and clogging equipment.
Defoamer: It can eliminate air bubbles and foam in water to ensure the normal operation of equipment.
