摘　　要：木聚糖酶用于漂白针叶木浆打浆前进行预处理,对打浆能耗,纤维特性,成纸性能及湿部电荷的影响进行了研究。结果表明:木聚糖酶预处理后能够降低打浆能耗,改善纸浆性能,增加纤维表面的润湿性能和纸浆Zeta电位绝对值有所下降。The influences of pretreatment of bleached softwood pulp with xylanase before beating on beating energy consumption, fiber morphology, paper properties and electric charge in the wet end invesgated in this paper. The results show that pretreatment with xylanase before beating can reduce beating energy comsumption, improve pulp properties, raise fiber surface wettability and the absolute value of Zeta potential.
