STUDY OF CARBOXYL METHYL STARCH ON PAPER STRENGTH

A novel starch derivative--carboxyl methyl starch (CMS) was investigated in this paper. Through a series of experiments, the results showed that CMS has considerable effect on paper strength as internal additive, and the better technology conditions are as follows: pH=7.0, CMS dosage is 1.0% (on o.d. pulp), mixing time is 45min and drying temperature is 105℃.

不同取代度羧甲基淀粉钠纸张增强性能的研究

介绍了一种用于造纸工业的淀粉衍生物———羧甲基淀粉钠(CMS)。主要研究了不同取代度的CMS对纸张的增强作用,研究表明:不同取代度的CMS对纸张增强效果不同,取代度为0.91的CMS对纸张的增强效果最好。

羧甲基淀粉钠纸张增强性能的初步研究

初步研究了pH值、羧甲基淀粉钠(CMS)的取代度对CMS纸张增强性能的影响。结果表明,在pH值为7时,CMS对纸张的综合增强效果最好;CMS的取代度对CMS的纸张增强效果有很大影响,高取代度CMS和低取代度CMS对纸张的增强效果比较好,而中取代度的CMS对纸张的增强效果不如高取代度和低取代度的CMS,其中以取代度为0.91的CMS对纸张的增强效果最好。
