细菌纤维素在草浆纸中应用的探讨

Application of Bacterial Cellulose in Nonwood Base Paper

利用电子显微镜观察了细菌纤维素的微观结构 ,其为典型的空间网络结构。利用显微镜观测纤维素湿膜打浆分散成单根纤维的横断面形态 ,末端呈锯齿型 ,其有利于纤维的分丝帚化。在浆料中加入细菌纤维素能够有效地提高填料的一次留着率。在苇浆中加入 1 0 % (g/g)的细菌纤维素可提高裂断长 2 2 % ,耐破指数 8% ,撕裂指数 5 %。

The network structure of bacterial cellulose was observed obviously by the electronic microscope. The wet pellicle of bacterial cellulose was separated into single fibers by beating and the top of the single fibers was in favor of fibrillation. Adding bacterial cellulose into the pulp can increase the first retention. By addition of 10% bacterial cellulose into reed pulp, breaking length of paper could increase by 22%, burst index by 8%, tear index by 5%.
