摘　　要：用商品纤维素酶处理马尾松热磨机械浆 (TMP) ,在一定酶活剂量作用下 ,能使纸浆的打浆度明显降低 ,而手抄纸的强度几乎不受影响 ;通过扫描电镜 (SEM)观察纸浆表面纤维形态的变化 ,发现纤维表面的细小纤维被清除。Masson pine thermomechanical pulp was modified by cellulase with different dosages. It was found that drainage of treated pulp could be improved and the strength properties of treated pulp did not drop off. Enzymatic hydrolysis on the fine structure of treated TMP pulp was investigated by scanning electro-microscopy. The results indicated that fines and fibrillation structure on the surface of pulp fibers reduced after enzymatic treatment.
