1, Properties

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.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 200℃.It can disociate into 8 positive-negative ions,thus can chelate with many metal icons to form polymer reticulation complex,to destroy the normal crystallization of calcium scale.EDTMPS shows better antiscale effects to calcium sulfate and barium.

2, Specification: confirm to HG/T 3538-2003

3, Application range &using method

EDTMPS can be used as corrosion inhibitor in circulating cool water sustem and boiler water.It is a chelating agent in noncyanogen electroplating industry and a water-softening agent in printing& dyeling industry.When used alone,2-10mg/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 buit with BTA,PAAS and zinc salt.

4, Package and Storage:

Normally EDTMPS packed with 25 kg net plastic Drun, or packed as customer,s required.Storage for ten months in room shady and dry place.
