EDTMP introduction: In lacks the anti- filthy medicinal preparation gentle etching reagentin the boiler aqueous system to be able to have massive scale and thecorrosion, but creates the thermal efficiency to reduce the wasteenergy, moreover also possibly can cause the steam to divulge, because scale seriously causes every year the accident surpasses the accidenttotal *0%; scale will form in the cooling system can reduce the flowchannel cross-sectional area, will increase the water cycleresistance, will hinder the normal heat change along with the scale unceasingly will add thick, will create equipment seriouscooling not good to bring a succession of evil consequence, willeffectively seek one kind effectively anti- to be filthy corrosion inhibitor becomes the urgent matter. EDTMP is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion ***** corrosion inhibition 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 tolerance. It shows excellent scale inhibition ability under temperature **0�. 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 shows better antiscale effects to calcium sulfate and barium sulfate. EDTMP application scope and application method: EDTMP 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~*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.
