碱木素作为纸板施胶增强剂的研究

本文研究了碱木素作为纸板施胶、增强剂对纸板物理性能的影响。结果表明：碱木素的加入有一个合适的用量，它能使纸板的施胶度、平滑度、耐破度和抗张强度有所增加，对撕裂度影响较小，但使白度、透气度、耐折度下降。

Study of Using Soda Lignin as Sizing and Reinforcing Agents

The effeets of using soda lignin as sizing and reinforcing agents on the physical properties of paperboard have been investigatad.The results indicate that the dosage of soda lignin should be suitable,the addition of soda lignin results in the improvement of sizing,smoothness,burst and tensile strength of paperboard,slight decrease of brightness,porosity and folding strength.It has small effect on the tear strength.
