Abstract:

Dendrimers are highly branched and three-dimensional macromolecules. Although industrial applications are relatively recent, dendrimers are common macromolecule in nature. Because of their unique geometric and chemical characteristics, dendrimers have demonstrated advantages in RO water treatment applications. Compared to straight-chain homopolymers, dendrimer-based antiscalant can more effectively control inorganic scale, colloids and organic material in ROfeedwaters. Its unique performance characteristics provide users with more complete control over RO systemfeedwaters, reducingmembrane fouling tendencies and minimizingmembrane cleaning requirements.

Key words: dendrimer, reverse osmosis, antiscalant

摘要：

树枝状聚合物是一种高度分叉的具有三维立体构造的高分子，虽然在自然界里树枝状聚合物很常见，但其工业应用却是刚刚开始。作者首先介绍了由于其独特的几何构造和化学特征，树枝状聚合物在反渗透水处理中所表现出的巨大的工业应用优势，进而重点介绍了相比于直链型聚合物，基于树枝状聚合物的阻垢剂可以更加高效地控制反渗透原水中的无机盐垢、胶体和有机物。最后得出结论，树枝状聚合物的独特性能可以提供给用户更加全面的反渗透系统给水控制，降低膜的污染倾向并减少膜的清洗需求。
