EDTMP· Na5 is a neutral product, EDTMP· Na5 is a nitrogen-containing organic polyphosphonate, which is a cathodic corrosion inhibitor. It is miscible with water, non-toxic and non-polluting, has good chemical stability and temperature resistance, and still has a good scale inhibition effect at 200°C. It can be dissociated into 8 positive and negative ions in aqueous solution, so it can be chelated with multiple metal ions to form a network complex of multiple monomeric macromolecular macromolecules, which are loosely dispersed in water to destroy the normal crystallization of calcium scale. EDTMP sodium salt has a good antiscaling effect on calcium sulfate and barium sulfate scale.
EDTMP· Na5 is used as a corrosion and scale inhibitor for circulating water and boiler water, a complexing agent for cyanide-free electroplating, a water softener for printing and dyeing industry, and a cooling water treatment for power plants.
