羟丙基甲基纤维素作为水泥添加剂研究(三)

Study of hydroxypropyl methyl cellulose as cement additive (part 3)

以三聚氰胺甲醛树脂磷酸盐（MS）为分散剂，羟丙基甲基纤维素衍生物为粘稠剂研究了它们的复合物对混凝土材料的分散性与粘稠性及其它性能的影响，并探索了其作用机理。

The effect of composile prepared with sulfonated formaldehyde-melamine copolymer asdispersing agent and hydroxynropyl methyl cellulose as viscous agent on the performance ofconcrete such as dispersion and viscous effect were studied and experiments were carried ontheir action principle on concrete.
