摘　　要： 对阳离子聚丙烯酰胺(CPAM)/改性膨润土和CPAM/胶体SiO2两种微粒体系对漂白麦草浆的助留助滤作用进行了探讨,确定了改性膨润土、胶体SiO2的最佳用量,对两种体系的助留助滤效果进行了对比,并结合纸浆的Zeta电位和扫描电镜初步探讨了复式助留助滤的机理。 In this paper, cationic polyacrylamide/modified bentonite and cationic polyacrylamide/colloidal SiO2 were used as retention anddrainage aids for bleached wheat straw pulp and their function on filler retention and drainability of pulp was studied. The optimal dosagesof cationic polyacrylamide, modified bentonite and colloidal SiO2 was determined and a comparison between the two systems was carriedout, too. The mechanism of retention and drainage was discussed through the measurement of Zeta potential and scanning electron microscopy.
