Properties:
EDTMP•Na5 is nitrogenous organic polyphosphonic acid, which is a part of cathodic corrosion inhibitor. It can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal tolerance. It has good scale inhibition property under temperature 200℃.
EDTMP•Na5 can dissociate into 8 positive-negative ions, thus can chelate with more than two metal ions to form more than two polymer reticulation complex, the complex can be quickly dissolved in water to destroy the normal crystallization of calcium scale. It shows better scale inhibition effects to calcium sulfate and barium sulfate.
