摘要
研究了阳离子淀粉(CS)与海藻酸钠(SA)二元增强体系对混合阔叶材KP浆所抄纸张的增强效果。结果表明:(1)单一加入阴离子助剂SA对纸张物理强度影响不大。(2)CS/SA二元增强体系对纸张物理强度提高的最大值均优于单一加入CS时对纸张增强效果的最大值。(3)CS/SA二元增强体系对纸张的耐折度影响最为明显。(4)浆料初始pH值约为7.0时,CS/SA二元体系对纸张物理强度的增强效果要优于酸性抄纸和碱性抄纸。
The effect of a binary paper strengthening system of cationic starch（CS） and sodium alginate（SA） is studied.The results are as fol-lows.（1） Adding a single anionic additive（SA） has little effect on the strength of paper.（2） The maximum of CS/SA binary paper strengthening system on the physical strength of paper is better than a single addition of CS.（3） The effect of the CS/SA binary system on paper folding endurance is most apparent.（4） When pulp’s pH is around 7.0,the effect of CS/SA bi-nary system on paper strength is better than the acidity papermaking and the alkaline papermaking.
