摘　　要：本文研究了聚乙烯亚胺(PEI)对白泥预处理后一些基本性能变化和用于加填时对施胶性能的影响。研究表明,通过不同pH值的PEI和机械处理白泥后,在粒径<10μm时,白泥的体积分数增大了9.37%-56.82%,而在10-30μm和>30μm的粒径范围内,白泥的体积分数都在减小。同时,预处理白泥加填后体系的Zeta电位值比未经处理白泥加填后体系的Zeta电位值小,体系变得不稳定。而预处理前后的白泥用于纸张加填时,经过预处理过程的白泥加填后施胶度比空白组PEI0的施胶度降低了56.60%-103.59%。This stu and its impact on s dy is focused on the difference of some basic properties after white mud pretreatment with PEI izing as filler. The result of the research reveals that the volume fraction of white mud after pre - treatment with different pH PEI and mechanical force increases about 9.37%--56.82% when particle size is less than 10μm. While particle size is more than 30μm and between 10 and 30μm,the volume fraction of white mud decreases . At the same time,Zeta potential of the system using pretreated white mud as filler is smaller than that of the system using unpretreated one . In addition, the sizing degree of adding white mud with pretreatment has a 56.60% - 103.59% reduction compared to blank group PE10.
