摘　　要：采用低打浆度的麻浆纤维作为原材料,分别加入三种不同的分散剂,优选出最适合麻浆纤维的分散剂,且探究了分散剂的加入量对麻浆纤维分散性以及纸张性能的影响。研究结果表明:优选出R200分散剂在麻浆中的分散效果最好,随着其加入量的增加,纸张的匀度指数、抗张强度、断裂伸长率这三个指标提升效果明显;通过孔径分析和扫描电镜检测可知,纸张中纤维与纤维之间的搭接更加均匀,纤维之间形成20μm以上的较大孔径几率降低。Low-beating degree hemp pulp fibers were used as raw materials,and three different dispersants were added to select the most suitable dispersant for hemp pulp fibers.The effect of the amount of dispersant added on the dispersibility of hemp pulp fibers and paper properties was investigated.The research results are as follows:R200 dispersant proved to have the best dispersion effect in hemp pulp.With the increase of its addition amount,the three performance improvement effects of the paper,including uniformity index,tensile strength,and elongation at break,are significant.Through pore size and scanning electron microscopy analysis,it was found that the overlap between fibers in the paper is more uniform,and the probability of forming larger pore sizes of over 20μm between fibers is reduced.
