Product Description

1. Properties and Uses
EDTMP-Na5 is a neutral product, EDTMP-Na5 is a nitrogen-containing organic polyphosphonate, a cathodic corrosion inhibitor. It is miscible with water, non-toxic and non-polluting, with good chemical stability and temperature resistance, and still has good scale inhibition effect at 200ºC. It can dissociate into 8 positive and negative ions in aqueous solution, so it can chelate with many metal ions, form many monomer structure macromolecular network complexes, loosely dispersed in the water, so that the normal crystallisation of calcium scale is destroyed.EDTMP sodium salt has a good scale inhibition effect on calcium sulphate and barium sulphate scale.
EDTMP-Na5 is used as corrosion and scale inhibitor for circulating water and boiler water, complexing agent for cyanide-free electroplating, water softener for printing and dyeing industry, and cooling water treatment for power plant.
The solid product of EDTMP-Na5 has slight moisture absorption, which is convenient for transport and use in cold conditions.
