HEDP is an organophosphoric acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions to form stable chelating compounds.It can dissolve the oxidized materials on these metals surfaces.
HEDP•KX is the potassium salt of HEDP, HEDP•K2 has better dissolution ability than that of sodium salt under neutral condition. HEDP•K2 is a good scale inhibitor for calcium carbonate, it can be used in metal corrosion inhibitor, antifouling agent of swimming pool, metal cleaning, volume cleaning, iron dust controlling, metal pretreatment, low pressure boiler water treatment and circulating water treatment, etc.
(1) HEDP can be wide used for industrial treatment water as corrosion and scale inhibitor, for example boiler water, cyclic cooling water and water of oil field.
(2) In addition, it is used as complexing agent in no cyanide electroplating, as metal cleaner and as stabilizer and fixation in blanch and dye industry.
(3) As the scale inhibitor ,it can well inhibit the scale of calcium carbonate.
(4) The adding weight concentr ation of active ingredient is 1-10mg/l. It often cooperates with dispersion-scale inhibitor in the use.
