摘　　要：研究了聚木糖酶预处理的影响因素。聚木糖酶预处理可改进Ｈ２Ｏ２漂白。添加表面活性剂和去除纸浆中重金属离子可改进聚木糖酶的作用效果。桉木硫酸盐浆经（ＱＸ）－Ｏ１－Ｉ－Ｏ２－Ｐ１－Ｐ２漂序，可漂至８８．８３ＳＢＤ的高白度，粘度为５６４ｍｌ／ｇ。聚木糖酶预处理可减少Ｈ２Ｏ２消耗。The influential factors of xylanase pretreatment were studied.The xylanase pretreatment could improve hydrogen peroxide bleaching.The addition of surfactant and the removal of heavy metal ions were of beneficial to xylanase treatment. The brightness and viscosity of bleached eucalyptus KP was 88.83%SBD and 564ml/g respectively,through the bleaching sequence (QX)-O 1-I-O 2-P 1-P 2.The xylanase pretreatment could reduce the consumption of hydrogen peroxide.
