| 摘 要： | 研究了Al2O3陶瓷底膜的表征方法。首先，根据毛细管作用原理、润湿现象及Laplace方程，采用异丙醇作为润湿剂，求出底膜的孔径、干膜流量和湿膜流量，用这些数据，导出孔径分布函数，并作出孔径分布函数与孔径关系图，其次，采用GB1966-80的方法，测定了Al2O3陶瓷底膜的孔隙率。

| Abstract: | Several methods of characterizing of alumina ceramic membrane were investigated in this paper. First, According to principle of capillary action and wetting phenomenon and Laplace equation, used iso-Propyl alcohol as wetting agent , pore size of alumina ceramic membrane, dry membrane discharge and wet membrane discharge could be solved. Using these data, the pore size distribution function could be solved. And, the chart of the relation between pore size distribution and pore size was drawn. Second, the porosity was determined, used the method of GB 1966-80. |
