摘要：

介绍了硬垢测定法的原理与方法,测定了高相对分子质量聚丙烯酰胺和不同聚合度马-丙共聚物的阻垢性能并与垢量法的测定结果进行了比较,从分子结构和粒子间相互作用的角度讨论了阻垢过程对阻垢剂的相对分子质量要求。最后对高相对分子质量聚电解质作为阻垢剂的应用前景进行了讨论。

Abstract:

A new method evaluating the properties of SCale inhibitor，the hard SCale determination，iS introduced．rI1le scale inhibitions of polyacrylamide with high molecule weight and maleic acid-acrylic acid copolymer with diferent molecule weight are observed． The results show that the SCale inhibitors are better with higher molecule weight． which are sufficiently diferent from the results of sediment amount detection method． Th e importance of molecule weight on scale inhibition iS discussed from the viewpoint of molecular structure and inter-molecule interaction．

Key words: scale inhibition, hard scale determination, relative molecule weight, poly—electrolyte
