摘　　要：本文探讨了用PulpzymeHC木聚糖酶对CEH漂程中浆料进行预处理,结果表明可以明显改善落叶松KP浆的漂白性能,纸浆白度可提高6% (SBD)以上或在相同白度下减少用氯量18. 75%;用酶处理替换碱处理的CXH漂程及用酶进行漂白后处理CEHX和CEH/X漂程,可提高纸浆白度3% (SBD)左右。The pretreatment of larch kraft pulp with Pulpzyme HC xylanase before CEH sequences was studied. The result indicates that the bleachability of larch kraft pulp can be improved. The brightness of bleached pulp increase 6%(ISO) at the same available chlorine charge or the available chlorine charge decreases from 8% to 6.5% at the same brightness. The brightness of bleached pulp can increase 3%(ISO) with CXH sequence instead of CEH sequence at the same C and H stage conditions.
