对比果胶酶和木聚糖酶不同处理流程的速生杨APMP制浆工艺。研究发现,经果胶酶和木聚糖酶联合处理的APMP制浆工艺取得较好效果,与未经任何酶处理的浆相比,经两种酶联合处理的浆,细小纤维含量和纤维束含量下降明显。成纸白度和不透明度有所提高,光散射系数降低。在强度性能方面,裂断长、耐破指数和撕裂指数分别提高7.64%、9.96%和10.71%。果胶酶单独处理对提升光学性能效果较为明显,木聚糖酶单独处理对提升强度性能效果较为明显。
Comparison of pectinase and xylanase different processing flow of poplar APMP pulping process. The results showed that the combination of pectinase and xylanase APMP pulping technology achieved good results, compared with the pulp without any enzyme treatment, the two enzymes combined treatment of pulp, fines content and fiber bundles Significant decline in content. Whiteness and opacity of the paper have increased, the light scattering coefficient decreased. In terms of the strength properties, long breakage, burst index and tear index increased by 7.64%, 9.96% and 10.71% respectively. Pectinase alone to improve the optical properties of the effect is more obvious, xylanase alone to improve the performance of the strength of the effect is more obvious.
