使用Youtell三种酶(A、B和C)和Novozym N476,在不同用量条件下处理全漂针叶木浆,分别测出酶处理纸浆的打浆曲线,纵向比较酶处理节约PFI打浆能耗的情况,横向比较至一定打浆度时所需酶的用量及PFI转数。初步分析了使用Youtell酶辅助打浆对纤维形态的影响。结果显示,在低酶用量下(小于2.5 IU·g~(-1)),三种打浆酶均能明显节约打浆能耗(约40%),较容易获得高打浆度的纸浆,同时酶促打浆对打浆度的提升存在极限值。纤维形态方面,相对于打浆酶A和B,打浆酶C更容易切断纤维。与Novozym N476相比,Youtell打浆酶在目标打浆度为低打浆度时存在优势。
Using Youtell three enzymes (A, B and C) and Novozym N476, the whole bleached softwood pulp was treated under different dosage conditions, the beating curve of the enzymatically treated pulp was measured, and the energy consumption of the PFI beating was compared longitudinally compared with the enzyme treatment, Laterally compared to a certain level of enzyme required when the amount of enzyme and PFI rotation. Preliminary analysis of the use of Youtell enzyme beating on the fiber morphology. The results showed that all three kinds of beating enzymes could significantly reduce the energy consumption of beating (about 40%) at low enzyme dosage (less than 2.5 IU · g -1), and it was easier to obtain high beating pulp while enzymatic Beating on the beating degree of upgrading there is a limit. In terms of fiber morphology, betelzyme C cuts the fibers more easily than dopes A and B. Compared with Novozym N476, Youtell beating enzyme has advantages when the target beating degree is low beating degree.
