1,Properties:EDTMP Na5is a neutral product,EDTMP Na5is a multi-nitrogen-containing organic phosphates, a cathodic type inhibitor. 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^oC. 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. EDTMP.Na₅ shows better antiscale effects to calcium sulfate and barium.EDTMP·Na₅ is used for circulating water and boiler water scale and corrosion inhibitor, non-cyanide electroplating of complexing agent, softening agent in dyeing industry, power plant cooling water treatment.Solid products ofEDTMP.Na5 have slightly moisture absorption , are convenient for transportation and usingin cold conditions.

2,Specification:

3,Application range&using method:EDTMPS can be used as corrosion inhibitor in circulating cool water system and boiler water. It is a chelating agent in non-cyanogen electroplating industry and a water-softening agent in printing & dyeing 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 built with BTA, PAAS and zinc salt.Organic phosphonic acid
