【摘要】 从填料自身的特性和湿部化学参数方面介绍了造纸过程中填料留着率对生产成本与环境的影响因素;对助留剂(单元助留体系、双聚合物助留体系、微粒助留体系、非离子型助留体系)的应用、填料与纤维改性技术(阳离子淀粉改性、填料的包覆改性、外表面细纤维化处理、阳离子淀粉改性纤维)和纤维细胞内加填等提高填料留着率的方法和研究进展进行了综述。研究结果表明:应用助留剂是提高填料加添应用效率最常用、最普遍的方法,而且微粒助留体系对填料的留着率优于单元助留体系和双聚合物助留体系。填料及纤维改性和纤维细胞内加填方法是现在研究的热点,虽然过程比较复杂,但取得的效果比应用助留剂的方法更好,具有一定的发展前景。更多还原

【Abstract】 In paper making process,the effects of filler characteristics and wet end parameters on filler retention for production costs and the environment are introduced.The methods and technologies that improve filler retention rate are reviewed from the aspects of retention aid application(unit retention aid system,double polymer retention aid system,particle retention aid system,non-ionic retention aid system),filler and fiber modification(cationic starch modification,packing coating modification,exterior surface fine fiber treatment,cation starch modification fiber) and lumen loading.The result is that application retention aid agent method is method of the most commonly used and the most common to enhance packing application efficiency,what is more,the effects of particle retention aid is better than unit retention aid system and double polymer retention aid system.Filler and fiber modification and lumen loading is research hot spot now,although the process is more complex but better result than applied retention aid agent methods,it has development prospect.更多还原
