Research Progress on Application of Nano-Materials in Papermaking Retention Systems

纳米材料由于其特殊的表面效应、量子尺寸效应等,在某些领域中具有较高的利用价值。近年来,造纸工作者正在致力于把纳米技术引入到制浆造纸的技术领域,取得了显著的效果。本文介绍纳米二氧化硅、纳米碳酸钙、纳米二氧化钛、纳米氢氧化镁铝和一些有机纳米材料在造纸助留系统中的应用情况,综述了目前国内外在此领域中的研究最新进展,指出了纳米材料应用于造纸助留剂的发展方向。

The nano-materials are high-value in many areas due to its special surface effect, quantum size effect and etc. In recent years, researchers were trying to introduce the nanotechnology into pulping and papermaking, and had got remarkable achievements. This paper introduces the application of nano-SiO2, nano-CaCO3, nano TiO2, nano magaldrate and nano organic materials in papermaking retention systems, and analyzes their performance advantages and shortcomings. The latest research in this field at home and abroad are reviewed, and the development of nano-materials used in papermakin~ retention systems is pointed out.
