摘　　要：研究了不同条件下混合办公废纸纤维素酶脱墨浆的纤维长度、细小纤维含量、纤维长度的分布情况以及纤维平均聚合度变化.结果表明:用单纯的纤维素内切酶脱墨几乎不会导致纤维平均长度下降,而内切酶与外切酶的协同作用会使纤维长度有较大降低;纤维素酶对纤维素聚合度变化的影响很小.Under different conditions, the fiber length, fines, distribution of fiber length and polymerization degree of cellulose were studied. The results showed that endoglucanases treatment alone did not result in the reduce average length. However, the synergetic effect of the endoglucanases and cellobiolhydralases could largely reduce fiber length. Cellulases only have small effects on the change of polymerization degree of cellulose.
