摘　　要：对羧甲基羟乙基瓜尔胶(CMHEG)在阔叶木漂白化学机械浆中的增强性能、助留助滤性能和纸张白度进行了研究。实验结果表明:当CMHEG用量为0.6%时,纸张获得较好的增强效果,相比原纸抗张指数提高21.3%,耐破指数提高38.1%,撕裂指数提高22.2%。该用量下,CMHEG对纸料的助留助滤有一定改善,而对纸张白度影响较小,其取代度对纸张的增强和助留助滤性能产生一定影响。Carboxymethyl hydroxyethyl guar gum（ CMHEG） using in the hardwood bleached chemimechamical pulp to increase strength,retention,drainage and brightness was studied. The experimental results show that when CNHEG dosage was 0. 6%,the paper get enhancement effect： tensile index increased by 21. 3%,burst index increased by 38. 1%,tear index increased by 22. 2% compared with the base paper. CMHEG has a certain improvement of paper＇s retention and drainage,but less influence on paper brightness. The substitution degree has an impact on enhancement,retention and drainage of paper.
