| 摘 要： | 分析了漂白针叶木化学浆、针叶木机械浆、再生浆和漂白芦苇化学浆的总电荷、表面电荷量。讨论了它们对反应性聚丙烯酰胺纸张增强性能和助滤性能的影响。研究结果表明，浆的表面电荷越大，N－氯代聚丙烯酰胺呈现最大的纸湿增强效果和助滤效果所需的定着助剂PDADMAC的量也愈大。

| Abstract: | The total charges and surface charges of kraft softwood bleached pulp, softwood mechanical pulp, waste pulp and reed chemical pulp were determined. Effects of the charge distribution in the pulps on functions of N chloropolyacrylamide were investigated. The results showed that the larger the surface charge densities were, the larger amounts of PDADMAC were needed to made N chloropolyacrylamide exhibit the largest improvement of paper wet strength and draining. |
