摘要
本文从微粒助留的角度对合理锂皂土与改性膨润土进行了比较与探讨,与湿法改性膨润土及干法改性膨润土相比,在阳离子聚丙烯酰胺单组分助留体系的基础上,合成锂皂土能够在加入量较小的条件下对纸料组分起到更为有效的微粒助留作用。
Microparticulate retention effect of synthetic Li-based bentonite and modified bentonite wasinvestigated and compared in this paper, with the result showing that, compared with modified bentoniteproduced by wet-modification method and dry-modification method, Li-based bentonite was more effectiveand efficent in furnish retention improvement when combined with cationic polyacrylamide.
