| 摘 要： | 为了研究溶剂中溶解气体和憎水颗粒表面纳米气泡对固-液溶胶性质的影响,采用深度脱气的方法对溶剂和分散质粒子进行处理,从而制备获得溶胶样品.对制备的溶胶样品进行了丁达尔效应和电导率的测定.丁达尔效应的测定结果表明:同一种胶体,经深度脱气的样品和未经深度脱气的样品相比较,前者具有更好的光散射现象.电导率的测试结果显示:经过深度脱气的溶胶样品的电导率,比未深度脱气的样品的电导率平均增加30%～80%.

| Abstract: | In this paper,the solid/liquid sol samples were prepared which solvent and dispersed particles treated with the deeply degassing method.Tyndall effect and the determination of conductivity had application in the measurement for the samples.The results of Tyndall effect showed that these samples prepared by the deeply degassing method had better light scattering phenomenon than no de-degassed samples.The test results of conductivity indicated that,the conductivity of sol samples which treated with the deeply... |
