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 液态水, innocuous and none pollution to environment, has good chemical stability and thermal tolerance. It shows excellent scale inhibition ability under 温度 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 液态水 system and boiler water. It is a chelating agent in non-氰气 electroplating industry and a water-softening agent in printing \u0026 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 压强 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、产品性能
本品是含氮有机多元膦酸，属阴极型缓蚀剂，与无机化合物聚磷酸盐相比，缓蚀率高3~5倍。能与水混溶，无毒无污染，化学稳定性及耐温性好，在200℃下仍有良好的阻垢效果。在水溶液中能离解成8个正负离子，因而可以多个金属离子合，形成多个单体结构大分子网状配位化合物，松散地分散于水中，使钙垢正常结晶被破坏。EDTMPS对硫酸钙、硫酸垢的阻垢效果好。二、质量指标 HG/T 3538-2003
二、技术指标
三、应用范围与使用方法
EDTMPS用于循环水和锅炉水的缓蚀阻垢剂、无电镀的络合剂、纺织印染行业螯合剂和氧漂稳定剂。在循环冷却水中单独投加时，一般剂量2~10mg/L。与HPMA按1:3比例复配后，可用于低压锅炉炉内水处理。EDTMPS也可与BTA、PAAS、锌盐等复配使用。
四、包装与贮存
EDTMPS塑料桶包装, 每桶25kg或根据用户需要确定。贮于室内阴凉处，贮存期十个月。
五 安全防护
EDTMPS为弱碱性，操作时注意劳动保护，应避免与皮肤、眼睛等接触，接触后应立即用大量清水冲洗。
