文章通过不同掺量萘系(UNF-5)和聚羧酸系(COPOCA202)超塑化剂的水泥颗粒表面电位试验和此两种超塑化剂饱和掺量以及未掺超塑化剂时水泥颗粒表面电位随时间变化试验,认为:超塑化剂的掺入使水泥颗粒电性统一,掺UNF-5带负电,掺COPOCA202则带正电,并随时间的延长其绝对值均逐渐降低;这种电性统一是新拌水泥浆体分散的重要来源;COPOCA202系比UNF-5对表面电位改变能力小。

本文通过超塑化剂在水泥颗粒表面的吸附试验、动电试验以及流变试验,研究了超塑化剂在水泥颗粒表面上的吸附特征、掺超塑化剂后的动电性质以及其对新拌水泥浆体结构的破坏特性,发现超塑化剂在水泥颗粒表面上的吸附可能是不均匀的,聚羧酸系超塑化剂(COPOCA202)对表面电位改变能力较萘系(UNF-5)的低,COPOCA202对絮凝结构的破坏能力较UNF-5大,并且即掺如COPOCA202浆体中还存在有絮凝结构,从而推断新拌水泥浆体中各个絮凝结构强度不均一。

补充资料：表面活性位
分子式：
CAS号：
性质：吸附剂和催化剂表面能量分布随区域不同而波动，波动显著时能量最低处为吸附中心。吸附中心一般即为催化反应的活性中心，亦称表面活性位。只发生在活性中心上的吸附为定位吸附。
