Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium (Edtmps) By Zaozhuang Dongtao Chemical Technology Co., Ltd.

These Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium (EDTMPS) is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion inhibitor. Its corrosion inhibition is 3~5 times better than that of inorganic polyphosphate. Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium (EDTMPS) is miscible with water, innocuous and none pollution to environment, has good chemical stability and temperature tolerance. It shows excellent scale inhibition ability under temperature 200oC. Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium (EDTMPS) can dissociate into 8 positive-negative ions, thus can chelate with many metal ions to form polymer reticulation complex, to destroy the normal crystallization of calcium scale. EDTMPS shows better antiscale effects to calcium sulfate and barium.
