Preparation method of large-flux ceramic membrane
The invention relates to a preparation method of a ceramic membrane, in particular to a preparation method of a large-flux ceramic membrane. The preparation method comprises the following steps: (1) preparing a support body, namely mixing aluminum oxide powder, titanium oxide powder, zirconium oxide powder and auxiliary materials according to a certain ratio, mixing, kneading, forming and drying the mixture, and finally sintering the mixture at high temperature to form the support body, wherein the flow channels in the support body are arranged in a manner of combining regular hexagonal flow channels and long hexagonal flow channels; 2) preparing a transition layer, namely mixing zirconium oxide powder, titanium oxide powder, aluminum oxide powder and auxiliary materials, and stirring, coating, drying and sintering the mixture at high temperature to form the transition layer; and 3) preparation of a filter membrane layer: mixing zirconium oxide powder, aluminum oxide powder and auxiliary materials, and performing stirring, coating, drying and high-temperature sintering to obtain the filter membrane layer with the filter precision of 20-200 nanometers. The ceramic membrane preparedby the method has the characteristics of high flux, high bending strength, strong pollution resistance and acid and alkali corrosion resistance.
本发明涉及陶瓷膜的制备方法，具体涉及一种大通量陶瓷膜的制备方法。包括以下步骤：1)制备支撑体，将氧化铝粉体、氧化钛粉体、氧化锆粉体和辅料按照一定比例混合，经过混料、捏合、成型、干燥、最后经高温烧结形成支撑体，支撑体的流道排列方式采用正六边形流道和长六边形流道相结合的形式；2)制备过渡层，将氧化锆粉体、氧化钛粉体、氧化铝粉体和辅料混合，经搅拌、涂膜、干燥和高温烧结形成过渡层；3)过滤膜层制备，将氧化锆粉体、氧化铝粉体和辅料混合，经搅拌、涂膜、干燥和高温烧结，得到过滤精度20‑200纳米的过滤膜层。采用本发明方法制备的陶瓷膜具有通量大、弯曲强度高、抗污染性强、耐酸碱腐蚀的特点。
