Properties of edtmps
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 can be fully dissolved in 液態(tài)水, innocuous and none pollution to environment, has good chemical stability and thermal tolerance. It shows excellent scale inhibition ability under 溫度 200℃. 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 sulfate.
Specification
Usage
EDTMPS can be used as corrosion inhibitor in circulating cool 液態(tài)水 system and boiler water. It is a chelating agent in non-氰氣 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 壓強(qiáng) boiler. It can also be built with BTA, PAAS and zinc salt.
Package and Storage
Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for ten months in room shady and dry place.

一、產(chǎn)品性能
本品是含氮有機(jī)多元膦酸，屬陰極型緩蝕劑，與無機(jī)化合物聚磷酸鹽相比，緩蝕率高3~5倍。能與水混溶，無毒無污染，化學(xué)穩(wěn)定性及耐溫性好，在200℃下仍有良好的阻垢效果。在水溶液中能離解成8個(gè)正負(fù)離子，因而可以多個(gè)金屬離子合，形成多個(gè)單體結(jié)構(gòu)大分子網(wǎng)狀配位化合物，松散地分散于水中，使鈣垢正常結(jié)晶被破壞。EDTMPS對(duì)硫酸鈣、硫酸垢的阻垢效果好。二、質(zhì)量指標(biāo) HG/T 3538-2003
二、技術(shù)指標(biāo)
三、應(yīng)用范圍與使用方法
EDTMPS用于循環(huán)水和鍋爐水的緩蝕阻垢劑、無電鍍的絡(luò)合劑、紡織印染行業(yè)螯合劑和氧漂穩(wěn)定劑。在循環(huán)冷卻水中單獨(dú)投加時(shí)，一般劑量2~10mg/L。與HPMA按1:3比例復(fù)配后，可用于低壓鍋爐爐內(nèi)水處理。EDTMPS也可與BTA、PAAS、鋅鹽等復(fù)配使用。
四、包裝與貯存
EDTMPS塑料桶包裝, 每桶25kg或根據(jù)用戶需要確定。貯于室內(nèi)陰涼處，貯存期十個(gè)月。
五 安全防護(hù)
EDTMPS為弱堿性，操作時(shí)注意勞動(dòng)保護(hù)，應(yīng)避免與皮膚、眼睛等接觸，接觸后應(yīng)立即用大量清水沖洗。
