本文讨论了水处理剂—马来酐—醋酸乙烯—丙烯酰胺三元共聚物铵盐的合成方法,对合成的产品进行了分子量测定和红外光谱的鉴定以及阻垢和缓蚀性能方面的试验。试验结果表明,本方法制备的三元共聚物铵盐除具有优良的阻垢性能外还具有一定的缓蚀作用,所得产品可作为阻垢兼缓蚀剂使用。文中还列举了本合成方法的一些优点。引言低分子量聚羧酸类化合物例如丙烯酸、马来酐等均聚物及其共聚物是冷却水处理中
In this paper, the synthetic methods of the water treatment agent - maleic anhydride - vinyl acetate - acrylamide ternary ammonium salt were discussed. The synthesized products were tested by molecular weight and infrared spectra and the scale inhibition and corrosion inhibition. The test results show that the ternary copolymer ammonium salt prepared by the method has certain corrosion inhibition effect in addition to excellent scale inhibition performance, and the obtained product can be used as scale inhibition and corrosion inhibitor. The article also lists some of the advantages of this synthesis method. INTRODUCTION Homopolymers of low molecular weight polycarboxylic acids such as acrylic acid, maleic anhydride and the like and their copolymers are water-cooled
