摘要:介绍了瓜尔胶、阳离子淀粉(CS)和羧甲基纤维素(CMC)的特性,比较了非离子瓜尔胶、阳离子瓜尔胶、阴离子瓜尔胶的性能,实验了浆内添加瓜尔胶、采用CS和CMC部分替代非离子瓜尔胶对纸张强度和填料留着率的影响。结果表明,在薄页纸浆内添加非离子瓜尔胶具有增强和助留效果,采用CS和CMC部分替代非离子瓜尔胶,也能提高纸张的强度性能和填料留着率。

Abstract:This paper described the characteristics of guar gum, cationic starch and carboxyalkyl cellulose, compared the performances of non-ionic guar gum, cationic guar gum and anion guar gum, and studied the application of guar gum and mixed application of non-ionic guar gum, cationic starch and carboxyalkyl cellulose.The results indicated that adding non-ionic guar gum in tissue pulp could enhance retention and tensile.Mixed application of non-ionic guar gum, cationic starch and carboxyalkyl cellulose could also improve strength of the paper and raise the retention of filler.
