摘要:探讨了聚乙烯胺填料改性剂对文化用纸生产的影响。结果表明,聚乙烯胺填料改性剂既能够提高填料留着率,又能够提高纸张的抗张强度、改善纸张的匀度,同时还可以降低聚丙烯酰胺（PAM）的用量和针叶木浆的配比,对降低生产成本有很好的作用。

Abstract:This paper discussed the effect of application of the polyvinylamine modified filler on the production of writing and printing papers. The results revealed that the modified filler improves the properties of the paper, which include retention rate, paper strength and formation. At the mean time, it can reduce the consumption of PAM and NBSK pulp, and it is benefit of cutting production cost.
