| 摘 要： | 研究了木聚糖酶预浸渍对光叶楮木片P-RC APMP制浆性能的影响。结果表明：在H2O2和NaOH用量均为3．0％的条件下，游离度在380mL左右时，酶法P-RC APMP（木聚糖酶用量为12U／g）纸浆和常规法P—RC APMP相比，抗张指数、耐破指数分别提高了27．4％、7．2％，且PC值减少了近20．6％。可用于配抄高档白纸板和白卡类纸板产品，在生产同档次纸板产品时，用酶法P—RC APMP纸浆配抄可以节省商品漂白木浆的用量。 |

| Abstract: | The effects of Xylanase pre-impregnation on P-RC APMP pulping performance from Broussonetia papyrifera wood chips were investigated. Results show that under the conditions of H202 and NaOH to the amount of 3.0%, freeness level of 380 mL, tensile and burst strength of the former （with a dosage of xylanase of 12U/g o.d. chip） are increased by 27.4% and 7.2% respectively, comparing with those of the latter, and PC value of the former is decreased by 20.6%. In conclusion, both processes could be used to produce advanced white paper board and white card paper board. When this method is used to produce product of the same grade, P-RC APMP pulps from Broussonetia papyrifera can save the amount of market bleached wood pulp. |
