对纸浆纤维阳离子化的研究进展进行了总结和评述。主要介绍和比较了纸浆纤维阳离子化的3种方法:直接阳离子化法,预聚物耦合法和阳离子高聚物接枝法。讨论了阳离子纤维的助留机理。阳离子纤维和可溶性阳离子聚合物配合使用有助于提高细小纤维和填料的留着率。
The research progress of pulp fiber cationization is summarized and reviewed. Three methods of cationization of pulp fiber are introduced and compared: direct cationization method, prepolymer coupling method and cationic polymer grafting method. The retention mechanism of cationic fibers is discussed. The combination of cationic fibers and soluble cationic polymers helps to increase retention of fines and fillers.
