摘 要

这些年来，水资源的匮乏、水污染治理成了全球性的难题，如何合理有效的利用水资源以及水资源的循环已经成为社会发展至关重要的问题。聚丙烯酸（PAA）作为一种优秀的水溶性阻垢分散剂，广泛的应用于水处理领域中。本课题主要研究合成不同PH下的PAA，用静态阻垢法测其效果。结果表明对于阻不同的物质的垢应选取适合的PH值。

关键词： 聚丙烯酸 阻垢 分散

ABSTRACT

Over the years, water scarcity and water pollution control has become a global problem, how rational and efficient use of water resources and water cycle of social development has become a critical issue. Polyacrylic acid (PAA) as an excellent water-soluble scale inhibitor and dispersant, widely used in water treatment field. The main research topics PAA synthesis under different PH, measuring the effect of static scale method. The results showed that the resistance of different scale materials should be selected for the PH value.

Keywords Polyacrylic acid ，Scale Inhibition， Dispersion
