摘　　要：对阳离子淀粉在高速新闻纸机上用来提高新闻纸表面强度进行研究。结果表明:添加阳离子淀粉能明显改善新闻纸的表面强度和抗张强度;纸张的撕裂度随着阳离子淀粉用量的增加呈现先上升后下降的趋势;阳离子淀粉能显著提高浆料的滤水性能以及保留率。The research was developed on improvement of newsprint＇ s surface strength by means of cationic starch in high speed paper machines.The result shows that addition of cationic starch dramatically increases newsprint＇s IGT and tensile strength.As the dosage of cationic starch increases,tear strength is firstly raised,then reduced later.Moreover,cationic starch can obviously improve pulp retention and drainage.
