Properties:
This product is nitrogenous organic polyphosphonic acid, which is a part of cathodic corrosion inhibitor, its property is 3~5 times better than that of inorganic polyphosphate. It can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal resistance. It shows excellent scale inhibition property under temperature 200gs? it 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. Edtmps shows better antiscale effects to calcium sulfate and barium sulfate.
Specification: meet criterion of hg/t 3538-2003

Properties: EDTMPS is brown yellow transparent liquid. It has good chemical stability and has excellent scale inhibition effect for calcium carbonate and calcium sulfate under 200 degrees. At the same time, it has good dispersion and corrosion inhibition performance. Usage: As the scale inhibitor in circulation chilled water and boiler water and is also used as a complexing agent or water softener in other industrial water.
HPAA is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safety in use, no toxicity, no pollution. HPAA can improve zinc solubility. Its corrosion inhibition ability is 5-8 times better than that of HEDP and EDTMP. When built with low molecular polymers, its corrosion inhibition effect is even better. HPAA is mainly used as cathode corrosion inhibitor in oilfield refill water system in fields such as steel & iron, petrochemcal, power plant and medical industries. When built with zinc salt, the effect is even better.
EDTMPA is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion inhibitor. Its corrosion inhibition is 35 times better than that of inorganic polyphosphate. It 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 200C. It 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.
