HEDP • Na4 is the sodium salt of HEDP is an excellent calcium carbonate scale inhibitors, HEDP • Na4 is mainly used for low pressure boiler water, circulating water treatment, industrial and municipal clean water, swimming pool sterilization of metal corrosion. HEDP • Na4 is white powder solid, soluble in water, does not absorb moisture, easy to transport, suitable for use in cold conditions. HEDP • Na4 bisphosphonates are organic corrosion inhibitor, with iron, copper, zinc and other metal ions to form stable complexes, can dissolve metal oxide surfaces. Still plays a good role in corrosion and scale under 250 ℃. HEDP • Na4 is widely used in electric power, chemical industry, metallurgy, fertilizer and other industrial cooling water, low pressure boiler, oil field water pipelines as scale and corrosion inhibition; HEDP • Na4 in the textile industry, can be used for cleaning metal and nonmetal agents, peroxide stabilizer and fixative printing and dyeing industry, non-cyanide plating complexing agents, chemicals additives.
