摘　　要： 用纸浆纤维筛分仪、FQA-纤维特性分析仪和扫描电子显微镜对不同预处理条件的麦草碱法化学机械浆的纤维特性进行了研究。结果表明,麦草碱法化学机械浆含有较多的P102/R203和P203组分,是其具有较高机械强度的原因,而木聚糖酶预处理可以进一步增加这部分纤维的含量,更有利于纤维的解离和提高纤维的柔软度,改善纸浆的物理性能。 wheat straw soda-mechanical pulp, hot water pretreatment-soda mechanical pulp of wheat straw, xylanase pretreatment-soda mechanical pulp of wheat straw and hot water ＋ xylanase pretreatment-soda mechanical pulp of wheat straw were studied by a BaueroMcNett fractionater, a fiber quality analyzer and a scanning electron microscope. The results showed that R2O3 ,P2O3 fractionation of wheat straw soda-mechanical pulp accounted for more than 50% and the S2 layer of the fiber was fibrillated in some degree, it is the reason of higher physical strength of the wheat straw Sodamechanical pulp. Pretreatment with hot water and xylanase prior to soda treatment improves fiber property and increases physical strength of soda-mechanical pulp.
