Multi-layer co-fired aluminum oxide ceramic plate support body as well as preparation method and application thereof
The invention relates to the technical field of porous ceramic material preparation, in particular to a multi-layer co-fired alumina ceramic plate support and a preparation method thereof. According to the method, the bottom layer, the transition layer and the top layer of the ceramic membrane supporting body are sequentially pressed under the gradient pressure condition through the compression molding technology, finally the needed supporting body can be obtained through drying and one-time co-firing, the process is simple, and operation is easy. The porosity and the pore size of different layers are effectively adjusted by controlling the material composition of the membrane layer and adjusting the gradient change of the particle size of each layer of aggregate, the pore size of the prepared ceramic flat plate support body is gradually increased from the top layer to the bottom layer, the filtering resistance can be reduced, and the filtering flux can be increased. According to the prepared flat ceramic membrane, the interface bonding strength of different membrane layers is improved, the technical performance problems of unmatched co-firing shrinkage, large product buckling deformation, low water flux and the like of a multi-layer membrane are solved, and the flat ceramic membrane has the comprehensive performance of being short in production process, low in preparation cost, high in membrane separation precision and the like and is suitable for large-scale production and application.
本发明涉及多孔陶瓷材料制备技术领域，具体涉及一种多层共烧氧化铝陶瓷平板支撑体及其制备方法。该方法通过模压成型技术在梯度压力条件下依次压制获得陶瓷膜支撑体的底层、过渡层、顶层，最后经干燥、一次共烧即可获得所需支撑体，工艺简单，容易操作。通过控制膜层材料组成和调节各层骨料粒径的梯度变化，有效调节了不同层的孔隙率和孔隙尺寸，制备的陶瓷平板支撑体的孔隙尺寸由顶层至底层逐渐增大，能够降低过滤阻力，增加过滤通量。本发明制备的平板陶瓷膜改善了不同膜层界面结合强度，解决了多层膜共烧收缩不匹配、产品翘曲变形大、水通量低等技术性能问题，具有生产流程短，制备成本低，膜分离精度高等综合性能，适合规模化生产及应用。
