以市售普通陶瓷板为基膜,不同盐基度的聚铝液为浸渍液,采用原位造粒法制备微孔γ-Al2O3陶瓷膜测定所制得的各种γ-Al2O3陶瓷膜的最大孔径、孔径分布曲线及最可几孔径采用扫描电镜观察膜的形貌,研究聚铝无机高分子盐基度对成膜的影响实验表明,采用高盐基度(667%以上)的聚铝浸渍液,才能制备成膜性能良好的超薄微孔陶瓷膜
Using commercially available ordinary ceramic plate as the base film, polyaluminum solution with different basicity of salt as the impregnating solution, the in-situ granulation method was used to prepare the microporous γ-Al2O3 ceramic film, and the prepared γ-Al2O3 ceramic films were measured Maximum pore size, pore size distribution curve and the most probable pore size Scanning electron microscopy was used to observe the morphology of the film. The influence of the basicity of the polyaluminum inorganic polymer on the film formation was studied. Experiments show that the high basicity (66.7% ) Of the poly aluminum impregnation solution, in order to prepare good film properties of ultra-thin microporous ceramic membrane
