新型多功能低膦阻垢分散剂在结垢型水中的研究和应用

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-271，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。

Researches on and application of multifunctional and low phosphonic scale inhibitor to scaling-typed water

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 static and corrosion tests. Oligomers containing phosphonic acid,sulphonic acid and carboxylic acid which have active functional radicals of carboxy,aldehyde,sulpho,phospho, etc . are added to the scale inhibitor. It can effectively control the depositions of scale such as CaCO 3, Ca 3(PO 4) 2,CaSO 4 and Fe(OH) 3,Zn(OH) 2 in 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.
