摘　　要：对两性瓜尔胶接枝共聚物(LGG-g-PAM)在蔗渣漂白硫酸盐浆中的增强性能进行了研究。实验表明:LGG-g-PAM7对浆料具有很好的增强效果,0.8%的用量即可满足需要。体系适宜pH范围是7￣10,且反应时间6￣8min较为合适。扫描电镜分析结果显示,加入LGG-g-PAM后,纸页匀度较好,而断纸主要以纤维断裂为主,说明其增强效果明显。This article dealed with the application of grafting copolymer of amphoteric guar gum（LGG-g-PAM） as strengthening agent of bleached bagasse kraft pulp. The results showed that the strength of pulp was improved when added LGG-g-PAM7,it could obtain good effect at charge of LGG-g-PAM 0.8%.The appropriate pH value was 7-10, reaction time was 6-8min.SEM showed that the formation of paper sheets treated with LGG-g-PAM was good and the fiber rupture mainly was in the condition of rupture, as shown that it could improve the strength of paper sheets significantly.
