Product Application of Bis-phosphonic acid tetrasodium salt CAS#3794-83-0

HEDP•Na4 is the sodium salt of HEDP and is an excellent inhibitor of calcium carbonate scale. HEDP•Na4 is mainly used for metal corrosion inhibition in low-pressure boiler water treatment, circulating water treatment, industrial and municipal clean water, and swimming pool sterilization. HEDP•Na4 is a white powder solid, easily soluble in water, non-hygroscopic, easy to transport, and suitable for use in severe cold conditions. HEDP•Na4 is an organic phosphonate scale and corrosion inhibitor that can form stable complexes with various metal ions such as iron, copper, and zinc, and can dissolve oxides on the surface of metals. It still has a good corrosion and scale inhibition effect at 250°C. HEDP•Na4 is widely used in electric power, chemical industry, metallurgy, and chemical
