细小纤维对竹浆PFI磨浆和成纸性能的影响

The Effects of Fines on Beating Performance and Paper Properties of Bamboo Pulp

本实验用扫描电镜和多媒体显微镜观察筛除细小纤维前后竹浆纤维的分丝帚化情况,分析研究竹浆中细小纤维的存在对其浆料性能和成纸性能的影响。结果观察到,在相近打浆度的条件下,筛除细小纤维后的竹浆长纤维分丝帚化比竹浆原浆的明显,成纸强度性能高。本实验从纤维形态方面来观察研究细小纤维对竹浆成纸强度的影响,是一种研究细小纤维对浆料性能影响的方法。

In this study, the fibrillation of fractionated fibers and non - fractionated fibers of bamboo pulp were ob-served by scanning electron microscopy and multi-media microscope, then the effects of fines on the pulp and paper strength properties were analysised, It was found that the fibers which were fractionated had better fibrillation and higher paper strength properties than the fibers which were not fractionated at the similar beating degree This paper showed that we can observe the morphology of fiber to study the effect of fines on the strength properties of paper, which is a way of study on the strength properties of paper.
