HEDP•Na4 is the sodium salt of HEDP and is an good scale inhibitor for calcium carbonate. It can be used in low pressure boiler water system, circulating water system, industrial and municipal cleaning water system and swimming pool.
HEDP•Na4 solid form is white powder, soluble in water, easily deliquescence, suitable for use in winter and freezing districts. It is a kind of organophorphonic acid scale and corrosion inhibitor, can form stable complex with Fe, Cu and Zn ions. It can dissolve the oxides on metal surface and has good scale and corrosion inhibition effect under 250ºC.
HEDP•Na4 is widely used in circulating cool water system, medium and low pressure boiler, oil field water pipelines as scale and corrosion inhibitor in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.
HEDP•Na4 is used as detergent for metal and nonmetal In light woven industry while in dyeing industry, it is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP•Na4 is used as chelating agent.
