Pentasodium Salt of Ethylene Diamine Tetra (Methylene Phosphonic Acid) USES

EDTMP•Na5 is a neutral product. It is nitrogenous organic polyphosphonic acid, which is a part of cathodic corrosion inhibitor. EDTMP•Na5 can be dissolved in water. It is non-toxic and pollution-free to environment. It has good chemical stability and heat resistance. EDTMP•Na5 still has good scale inhibition effect under temperature 200℃. It can dissociate into 8 positive and negative ions. Thus it can chelate with multiple metal ions to form a plurality of monomeric structural of macromolecule reticular complex. The complex can be dissolved in water to destroy the normal crystallization of calcium scale. EDTMP•Na5 has better scale inhibition effects to calcium sulfate and barium sulfate.

EDTMP•Na5 can be used as scale and corrosion inhibitor for circulating water and boiler water system, chelating agent in non-cyanide electroplating, water-softening agent in dyeing industry, etc.

The solid of EDTMP•Na5 is slight moisture absorption. It is easy to transport and use in cold conditions.
