摘　　要：纤蛇纹石微粒具有高的正电性,且随着pH值降低,正电性逐渐增加;其阳离子微粒单独作为造纸助留剂使用,助留效果差,抗剪切性能也差;它与APAM配合使用,具有良好的助留效果、良好的抗剪切性能和在酸碱性纸料中的适应性,且其价格比传统的微粒体系具有明显优势。因此,该助留助滤体系具有发展潜力。Chrysotile microparticle was highly cationic, and its Zeta potential increased as the pH value decreased, When only chrysotile microparticle was used as retention aid. the retention effect was poor. and the floccus was easy to be destroyed when it was sheared. When chrysotile microparticle and APAM retention aid system was used. there had excellent retention effect, and this retention system was influenced little by pH value and the speed of shearing.
