摘　　要：用PFI磨对漂白化学竹浆进行磨浆,与阔叶木浆和针叶木浆对比,分析竹浆纤维各组分含量变化。研究筛分所得原生细小纤维的种类及在磨浆过程中的变化,探究二次细小纤维的来源,及对浆料和成纸性能的影响。结果发现,筛除浆料中的二次细小纤维之后,成纸的强度性能大大降低,但松厚度有所提高。Kraft bamboo pulp was refined by PH beater, the changes of different component of bamboo pulp were analyzed, The species and changes during refining of native fines were researched. The origin of secondary fines and the affect on pulp and paper properties were explored. We found that after the secondary fine was screened the strength properties of paper would be affected greatly, however the bulk value was improved.
