研究了不同的商品酶处理(纤维素酶、聚木糖酶或其混合物)对漂白硫酸盐浆的影响,评估了酶对3种桉木浆中还原糖释放和纤维长度变化的影响。研究结果发现,尽管实验中酶的用量非常大,但用单一酶制剂处理的浆料,纤维长度几乎没有变化,而使用纤维素酶与聚木糖酶的混合物处理浆料,其纤维长度、细小纤维含量和还原糖释放量都发生了显著变化,而且,所有的酶应用后都可导致导管细胞碎裂。此外,评价了在各种打浆条件下酶处理浆料的物理性能和化学性能,并与未经酶处理的浆料进行了对比。酶处理后,为提高纸浆性能所需的能量可节约17%,但浆料质量略有下降。
The effect of different commercial enzyme treatments (cellulase, xylanase or mixtures thereof) on bleached kraft pulp was evaluated and the effect of enzymes on the release of reducing sugars and the change in fiber length in three eucalyptus pulp was evaluated. The results showed that, although the amount of enzyme used in the experiment was very large, slurries treated with a single enzyme preparation had almost no change in fiber length, whereas slurries were treated with a mixture of cellulase and xylanase whose fiber length, Fiber content and reducing sugar release have undergone significant changes, and, after all the enzymes can lead to catheter fragmentation. In addition, the physical and chemical properties of the enzyme-treated slurry under various beating conditions were evaluated and compared with those of the untreated slurry. After enzymatic treatment, the energy required to increase the pulp performance can be saved by 17%, but the quality of the slurry decreases slightly.
