Description
HEDP•Na4 is the sodium salt of HEDP,
HEDP•Na4 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.
The solid
HEDP•Na4 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, it has good
scale and corrosion inhibition effect under **0?.
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.. In
light woven industry,
HEDP•Na4 is used
as detergent for metal and nonmetal. In dyeing industry,
HEDP•Na4 is used as peroxide stabilizer
and dye-fixing agent; In non-cyanide electroplating,
HEDP•Na4 is used as chelating
agent. Specification:
