| 摘 要： | 选取六偏磷酸钠(SHMP)、十二烷基苯磺酸钠(SDBS)及KCl作分散剂,并采用超声分散方法,制备纳米SiO2悬浮液,对纳米SiO2的水中分散性能进行研究。测试分散体系中纳米SiO2粒子的粒径及分布、Zeta电位及透光率,探讨了不同分散剂对纳米SiO2分散性能的影响。结果表明:不同分散剂对纳米SiO2的粒径都有明显影响,但粒径分布宽度差别较大;同在分散粒径较小的条件下,分别添加3种分散剂的悬浮液体系具有不同的稳定性,其中含SDBS的分散体系因静电和空间位阻的作用而表现出良好的分散稳定性。

| Abstract: | Through ultrasonic treatment,the suspension of SiO2 nano-powder in water is prepared by utilizing sodium hexametaphosphate(SHMP),sodium dodecylbenzenesulfonate(SDBS) and KCl as the dispersants respectively.The effect of different dispersants on the suspension stability is investigated by means of testing the particle size of nano-SiO2,the Zeta potential and photic transmittance of the suspension.The results show that all the dispersants have a significant effect on the particle size of nano-SiO2,however,the... |
