本文通过对云景思茅松硫酸盐浆进行打浆和抄纸实验,考察了纤维形态在打浆过程中的变化规律;研究了不同打浆方式、打浆度对成纸动态力学性能的影响。结果表明:PFI打浆有利于提高思茅松纤维成纸的抗张强度和耐破强度;Valley打浆对纸页动态力学性能的影响要明显优于PFI打浆;思茅松纤维有利于提高纸页的动态弹性模量和损耗因子。 In this paper, the kiwifruit pine kraft pulp beating and papermaking experiments were carried out to investigate the change of fiber morphology during the beating process. The effects of different beating methods and beating degree on the dynamic mechanical properties of paper were studied. The results showed that: PFI beating is conducive to improve the tensile strength and bursting strength of paper; the effect of Valley beating on the dynamic mechanical properties of paper is better than that of PFI beating; Modulus and loss factor.
