| 摘 要： | 研究了沙柳P-RC APMP进行酶处理后浆料性能的变化.结果表明,与空白样相比,聚木糖酶处理、漆酶/介体处理和漆酶/聚木糖酶处理对浆料光学性能的影响各不相同,浆料裂断长分别降低了9.5％、0.8％和6.7％,耐破指数分别降低了11.0％、4.1％和13.8％,撕裂指数分别提高了8.3％、8.0％和1.3％；扫描电镜观察发现,聚木糖酶处理后浆料纤维表面细纤维化程度变大,漆酶/介体处理后浆料纤维表面比较光滑,并出现部分表皮大块脱落的现象,与前述纤维相比,漆酶/聚木糖酶处理后的纤维分丝帚化程度最高；X射线衍射分析发现,酶处理后浆料纤维素的结晶度均下降,分别降低了6.0％、5.9％和2.4％.

| Abstract: | The effect of enzyme pretreatment on the properties of Salix Psammophila P-RC APMP was studied.The effects on optical properties of the pulp from pretreated Salix Psammophila by xylanase,laccase medium and laccase /xylanase were all different,the breaking length of the pulp reduced by 9.5%,0.8% and 6.7%,and the bursting index reduced by 11.0%,4.1% and 13.8%,the tearing index improved by 8.3%,8.0% and 1.3% respectively compared with the pulp from unpretreated new material.X-ray diffractometer analysis indicated that the crystallinity of the cellulose reduced after enzyme pretreatment. |
