| 摘 要： | 采用PFI磨浆机对杨木APMP浆进行打浆,分别研究打浆对纤维形态及质量、成纸性能的影响。利用光学显微镜及纤维质量分析仪(FAQ)观测纤维形态变化,分析了纤维的长度、卷曲、扭结等形态参数及细小纤维含量的变化。对高低游离度浆料进行配抄,与二段磨后浆料即成品浆料的成纸性能进行比较。选出性能较好的一组配比浆料,在该配比下进行白卡纸层合。结果表明:随着磨浆程度的提高,纤维长度下降,纤维卷曲指数与扭结指数先增加后下降,细小纤维含量增加。中浓磨浆后纤维的切断少,纤维压溃变得比较显著,纤维分丝、帚化优越,表现出了较好的纤维间结合能力。通过高低游离度配比的浆料成纸松厚度比成品浆成纸松厚度有所提高,仅对抗张指数和内结合强度方面的影响不太相同。而层合后成纸物理强度除抗张强度外普遍提高。

| Abstract: | The aspen APMP was beated using PFI refiner,and the effects of beating on fiber morphology and quality,papermaking performance were studied.The changes in fiber morphology,analysis of fiber length,curl,kink and other morphological parameters and changes in fines content were observed through optical microscope and fiber quality analyzer(FQA).The high-low freeness pulps were mixed to the same level of the secondary refining pulp,then the papermaking performance of the mixed pulp was compared to that of the s... |
