摘要:主要分析了盘磨机种类及打浆酶预处理对漂白针叶木浆(NBKP)和漂白阔叶木浆(LBKP)打浆能耗的影响。结果表明,对于NBKP和LBKP浆,在达到相同的打浆效果时，使用柱形磨打浆均比使用双盘磨打浆的单位打浆总能耗低；打浆酶和柱形磨相结合处理NBKP浆后,其单位打浆总能耗比只使用柱形磨的大幅降低。

Abstract:Application of enzymes in the pulp and paper industry has grown rapidly since the mid-1980s. Refining or beating of chemical pulp is one of the most important operations when preparing papermaking fibers for papers or paperboards production. Effect of enzyme pre-treatment before refining and the type of refiner on refining energy consumption of bleached softwood kraft pulp (NBKP) and bleached hardwood kraft pulp (LBKP) was analyzed in this work. Results revealed that the specific refining energy consumption of LBKP and NBKP with using cylindrical refiner was lower than that of using disc-type refiners. There was great difference of refining energy consumption with or without enzyme pre-treatment when cylindrical refiner was used to treat commercial NBKP.
