以阳离子淀粉(CS)和羧甲基纤维素(CMC)为纸张的二元增强系统,研究了其对纸张的增强程度。研究结果表明,单独添加占绝干纤维质量2. 2%的阳离子淀粉时,纸样抗拉指数提高了6. 4% ;单独添加占绝干纤维质量4. 4%的羧甲基纤维素时,纸样抗拉指数提高了2. 6%;当阳离子淀粉和羧甲基纤维素复配使用时,且添加总量为2. 2%,配比为10 :0. 8 时,纸样抗拉指数增幅达到15%以上。

Cationic Starch (CS) and Carboxymethyl Cellulose (CMC) were taken as binary strengthening system of paper. The strengthening degree of the binary strengthening system was studied. The result showed that the tensile index of paper improves 6. 4% when using about 2. 2% on dry weight of the cellulose CS alone; when using 4. 4% CMC alone, the tensile index of paper improves 2. 6%; when the ratio of CS :CMC is 10 :0. 8 and the total adding amount is about 2. 2% on dry weight of the cellulose, the improvement of the paper's tensile index reaches over 15%.
