| 摘 要： | 研究了阳离子硅镁石微粒的性能和其作为助留剂的助留效果。研究发现,硅镁石微粒具有纳米级的粒径和较高的正电性,其正电性随着pH值的增加逐渐降低;随着研磨时间的延长,硅镁石微粒的粒径逐渐降低,但其正电性也随着明显降低。硅镁石阳离子微粒单独作为助留剂使用时,具有一定的助留效果,但其用量大,且抗剪切性能差。硅镁石微粒与阴离子聚丙烯酰胺(APAM)组成的双元助留体系具有良好的助留效果,其中,未研磨的硅镁石微粒/APAM组成的体系具有良好的抗剪切性能和pH值适应性。因此,未研磨的硅镁石微粒与APAM组成的助留体系是一种理想的助留体系。

| Abstract: | The characteristic of nanometer cationic humite micro-particle and its effect as a retention and drainage aid were studied in this paper. The results showed that the nanometer cationic humite micro-particle has high cationic Zeta potential. Its cationic Zeta potential increases while pH value dropps, and decreases while grinding time increases. The retention of the fillers and fines improves in certain degree when a large amount of nanometer cationic humite is added alone which is sensitive to shear. When n... |
