针对石家庄医药化工厂严重结垢型水质及工况条件,通过静态阻垢试验和腐蚀试验,对原有配方进行了改进,研制出新型多功能低膦阻垢分散剂TS - 2 71,该药剂中加入了新研制的膦磺羧酸多元共聚物,由于药剂中含羧基、醛基、磺酸基、膦酸基等特效基团,对分散水中的CaCO₃ 、Ca₃ (PO₄)₂ 、CaSO₄及Fe(OH)₃ 、Zn(OH)₂ 等效果良好,与其他水处理剂混溶性较好,并能与锌盐很好复配,达到优良的缓蚀性能。该药剂经过 3a的实际应用,证明其具有优良的阻垢性能,特别对CaCO₃ 垢有特效。

Aiming at the quality of the most serious scaling-typed water and working conditioins in Shijiazhuang Medical Chemistry Plant, the multifunctional and low phosphonic scale inhibitor TS -271 is chosen through stat- ic and corrosion tests.Oligomers-containing phosphonic acid, sulphonic acid and carboxylic acid which have ac- tive functional radicals of carboxy,aldehyde,sulpho,phospho, etc.are added to the scale inhibitor.It can effec- tively control the depositions of scale such asCaCO3, Ca3(PO4)2,CaSO4and Fe(OH)3,Zn(OH)2in water.It is a good corrosion inhibitor as well,when it is accompanied well with other agents particularly with zinc.The tests and applications show that TS -271 has excellent scale inhibition performance for scaling-typed water.
