EDTMPS(Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium)

Description

EDTMPS (Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium)
CAS No. ********1
Similar to Dequest: ***0

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. EDTMPS can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal tolerance. EDTMPS shows excellent scale inhibition ability under temperature **0centigrade. 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 sulfate.

Usage of EDTMPS:
EDTMPS can be used as corrosion inhibitor in circulating cool water system and boiler water. EDTMPS is a chelating agent in non-cyanogen electroplating industry and a water-softening agent in printing & dyeing industry. When used alone, 2~*0mg/L is preferred. When built with HPMA by ratio ETDMP: HPMA=1: 3, it can be used for low pressure boiler. It can also be built with BTA, PAAS and zinc salt.

Package and Storage of EDTMPS:
Normally In **0kg net Plastic Drum, IBC drum can also be used as required. Storage for ten months in room shady and dry place.
