为了改善杨木高得率浆的配抄性能,扩大其应用范围,研究探讨了纤维素酶预处理对杨木碱性过氧化氢机械浆( APMP浆)配抄性能的影响。结果表明,与未经过酶预处理的杨木APMP浆相比,酶处理后 APMP 浆打浆能耗最大可降低19%,纤维吸水润胀程度增加,保水值增加12.6%；与不同比例针叶木漂白硫酸盐浆( BKP浆)配抄后,纸张的裂断长、耐破指数和撕裂指数均有所提高,最大可分别提高6.1%,44.6%和30.3%,纸张的松厚度、白度和不透明度稍有降低。纤维质量分析仪(FQA)、扫描电镜(SEM)和X射线衍射(XRD)分析结果显示,酶处理后纤维平均长度增加7.0个百分点,细小纤维组分减少10.0%,纤维卷曲指数降低22.4%,结晶度提高0.7%。可见,纤维素酶预处理可以改善杨木APMP浆的配抄性能,提高纸浆纤维质量,所配抄的纸张的物理强度性能指标有显著提高。

Cellulase pretreatment was utilized to treat the poplar alkaline peroxide mechanical pulp ( APMP) in present study to improve its papermaking performance and expand the application. The results showed that the beating energy consumption of the pretreated APMP decreased by 19% maximum and water retention value increased by 12. 6%, compared to the virgin APMP. Meanwhile, the breaking length, bursting index and tearing index of the papersheets, which were furnished by pretreated APMP and blended with different ratio of softwood bleached kraft pulp (BKP), increased maximum by 6. 1 %,44. 6 % and 30. 3%respectively. However, the bulk, brightness and the opacity were decreased slightly. The fiber quality analysis( FQA) , scanning electron microscope(SEM) and X-ray diffraction(XRD) were employed to characterize. The analysis results indicated that the fiber length increased by 7. 0%, the fines content decreased by 10. 0%, and the curl index decreased by 22. 4% compared with the pretreated APMP with the virgin APMP. Beside, a 0. 7% increase of the crystallinity was observed. Cellulose pretreatment can improve the fiber quality of poplar APMP. The resulted in a better physical strength property.
