PMAH-AM-MA的阻垢性能研究

Study on the Scale-inhibiting Performance of PMAH-AM-MA

以水为溶剂 ,马来酸酐、丙烯酰胺、丙烯酸甲酯为单体 ,过氧化二苯甲酰为引发剂 ,合成了水溶性的聚合物聚马来酸酐 -丙烯酰胺 -丙烯酸甲酯 ,并对该聚合物的阻垢分散性能进行了研究 .试验结果表明 ,PMAM是一种高效多功能阻垢剂 .其阻碳酸钙垢的效果达 86 .79% ;阻磷酸钙垢的效果达 94 .2 7% ;阻硫酸钙垢的效果达 74 .4 0 % 。

PMAH-AM-MA was synthesized with Maleic anhydride,meantime taking Acrylamide and Methyl acrylate as monomers, water as solvent and BPO as initiator. The performance of PMAM was studied,and the results show that PMAM is a soluble and very effective and multifunctional scale inhibitor. Inhibiting scale ratios of PMAM to CaCO 3 ,Ca 3(PO 4) 2 and CaSO 4 are 86.79%, 94.27% and 90.08%,respectively.It is also very effective in stabilizing Zn and dispersing Fe 2O 3.
