摘要
得到了一系列有机液体在粉末上的接触角的数值和表面活性剂在这些粉末上表现的性质,并做了定性和定量分析。实验原理建立在把渗透的液体进入玻璃管内粉末形成的多孔塞基础上,将Washburn方程用于毛细管内液体的流动用于计算液体和粉末之间接触角大小。结果显示了有机液体分子在石墨、铝粉上表面吸附的细节,并讨论其在科研和生产实践中的应用。
The contact angle of a series of organic liquids and the properties of surfactants on powders were studied. Both of qualitative analysis and quantitative analysis were also done. Experiment principle was based on the porous plug when penetrative liquids went into the powders. The contact angle between the liquid and the powder was calculated by applying Washburn equation into the flow of the liquid in capillary. The results of the experiments showed the adsorption of the organic liquids on the surface of graphite and aluminum and the applications of it in scientific research and manufacture were also discussed.
