苇浆二次纤维强度性能改善的研究

The Study of Improving the Properties of Recycled Reed Pulp

用半纤维素酶、纤维素酶以及物理、化学方法分别处理苇浆二次纤维，均使其成纸物理强度得到不同程度的提高，并探讨了这些处理方法的作用机理和最佳条件。

Tensile,burst and folding strength decreased when reed pulp were recycled.Biological,physical and chemical methods were used to treat recycled reed pulp for improving these strength properties in this studies.The results showed treating the recycled reed pulp with cellulase or hemicellulase improved its swelling properties so upgraded paper strength properties effectively. The enzyme dosage,treatment time,refining consistency,anionic polyacryamide resin aids,etc.are investigated.
