从混凝土减水剂的微观特征看减水剂的合成

从混凝土减水剂的活性官能团、分子结构和分子量三个方面分析了减水剂的微观特征及在合成中存在的问题,认为：开展聚磺酸-聚羧酸系高性能减水剂的研究是应该深入而有价值的;减水剂的梳状结构使减水剂具有非常好的分散性能,这是减水剂合成的重要方向;关于减水剂分子量的研究还存在一些问题,还需要深入进行探讨.

Discuss on the plasticisers synthesis based on the microscopic features of concrete plasticisers

In this paper,the microscopic features of concrete plasticisers and the problems of the plasticisers synthesis are analyzed based on three aspects of plasticisers, i. e. active groups, molecular structure and molecular weight. Researches find that it is worth deeply and valuable to study the poly acid-poly carboxylic high performance water-reducing agent; it is an important direction of plasticisers with comb structure, because the plasticisers with comb structure have very good dispersion performance; there are some problems about the study of molecular weight of plasticisers and need to be discussed.
