摘要
本文对作为纸张增强荆的羧甲基淀粉钠(CMS)的增强机理进行了初步研究。结果表明,CMS对纸张有明显的增强作用,且随取代度的升高有增强趋势;CMS溶液中的氯化物含量越高,对增强效果起到积极作用越大:CMS对细小纤维具有一定的助留作用,且随着取代度的增加有增强的趋势;CMS的粒子表面电荷越高,羧甲基淀粉钠的增强效果越好。
The strengthening principle of carboxyl methyl starch which is used as a strengthening auxiliary of paper is studied in this paper. The conclusions are got as follows： CMS can notably strengthen the paper＇s strength, and the strength function improves as the replacing degree improves; The higher content of chloride in the solution of CMS play a positive role to the strengthening result; CMS can increase the retention of micro fibers, and the function improves as the replace degree improves; When the surface electric charge in the solid particle gets higher, the better strengthening result can get.
