乙二胺四甲叉膦酸钠 EDTMPS

乙二胺四甲叉膦酸钠&nbsp;&nbsp;EDTMPS<br />&nbsp;&nbsp;Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium<br />【CAS】&nbsp; &nbsp; 1429-50-1<br />别名：乙二胺四亚甲基膦酸钠&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;Dequest 2040<br />分子式&nbsp; &nbsp;&nbsp;&nbsp;C6H12O12N2P4Na8&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; 相对分子质量：612.13<br />一、EDTMPS产品性能<br />EDTMPS是含氮有机多元膦酸，属阴极型缓蚀剂，与无机聚磷酸盐相比，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。EDTMPS在水溶液中能离解成8个正负离子，因而可以与多个金属离子螯合，形成多个单体结构大分子网状络合物，松散地分散于水中，使钙垢正常结晶被破坏。EDTMPS对硫酸钙、硫酸钡垢的阻垢效果好。<br />二、EDTMPS质量指标&nbsp; &nbsp;符合HG/T 3538-2003<br />项&nbsp; &nbsp;&nbsp; &nbsp;目&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;指&nbsp; &nbsp;&nbsp;&nbsp;标<br />外&nbsp; &nbsp;&nbsp; &nbsp;观&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;黄棕色透明液体<br />活性组分 (以EDTMPS计)%&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;≥30.0<br />有机膦（以PO43- 计）%&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;≥10.0<br />亚磷酸（以PO33-计）%&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;≤5.0<br />磷酸（以PO43-计）%&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;≤1.0<br />PH值（1%水溶液）&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;9.5～10.5<br />密度20℃(g/cm3)&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;≥1.25 <br />氯化物（以Cl-计）%&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; ≤3.0<br />三、EDTMPS应用范围与使用方法<br />EDTMPS用于循环水和锅炉水的缓蚀阻垢剂、无氰电镀的络合剂、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。EDTMPS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。 <br />四、EDTMPS包装与贮存<br />EDTMPS用塑料桶包装, 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。<br /><br /><br /><br /><table cellspacing="0" width="417" align="center" class="t_table"><tr><td width="202"><font size="3"><font color="#000000"><font face="宋体 ">联 系 人：姚娅<br /></font></font></font></td><td width="215"><a href="http://www.chinadada.com/" target="_blank"><font face="宋体 "><font size="3"><font color="#000000"></font></font></font></a></td></tr><tr><td colspan="2"><font face="宋体 "><font size="3"><font color="#000000">电<br />话：0632－5113088，3460157，3460158，5113066</font></font></font></td></tr><tr><td colspan="2"><font face="宋体 "><font size="3"><font color="#000000">公司主页：<a href="http://www.th-water-treatment.com" target="_blank">www.th-water-treatment.com</a></font></font></font></td></tr><tr><td colspan="2"><font size="3"><font color="#000000"><font face="宋体 "><br />www.th-chem.com</font></font></font></td></tr><tr><td><font size="3"><font color="#000000"><font face="宋体 "><br />www.thchem.cn</font></font></font></td><td><a href="http://www.cg180.com/" target="_blank"><font face="宋体 "><font size="3"><font color="#000000"></font></font></font></a></td></tr><tr><td><font size="3"><font color="#000000"><font face="宋体 "><br />www.thchem.com</font></font></font></td><td><a href="http://www.clii.com.cn/" target="_blank"><font face="宋体 "><font size="3"><font color="#000000"></font></font></font></a></td></tr><tr><td colspan="2"><font size="3"><font color="#000000"><font face="宋体 "><br />www.taihe-water.com</font></font></font></td></tr><tr><td colspan="2"><font size="3"><font color="#000000"><font face="宋体 "><br />www.thwater.net</font></font></font></td></tr></table><br /><br />[<i> 本帖最后由 sdthscl 于 2007-7-27 09:08 编辑 </i>]
