摘要
本文研究了阳离子淀粉对麦草浆手抄片的增强作用,并和淀粉磷酸酯、双元系统的增强作用进行了比较,增强顺序为:双元系统>阳离子淀粉>淀粉磷酸酯。最佳添加量,对双元系统两种淀粉各为1.0%(对绝干浆),对阳离子淀粉为2%,对淀粉磷酸酯为2.5%,此外,对矾土对纸张强度的影响也作了研究。
The strength-improving effect and mechanism of cationic starch added to the paper made of straw pulp are investigated.The results as follow:the strength- -improving order is dual system>cationic starch>starch phoshate,the best usages are dual system(cationic starch:starch phosphate=1:1),cationic starch:2%,starch phosphate:2.5%. We have also studied that Alum can improve paper strength.
