采用膜与载体共烧结的方法制备了一种超渗透、高选择性的双层氧化铝微滤膜。硅溶胶作为支架的助烧结剂还可以促进支架与膜之间的粘附。本文介绍了压带铸造技术，形成预膜，直接转移涂覆在绿色支撑体上。研究了最佳共烧结条件以及有机剂含量和膜厚度对膜性能的影响。在1300℃共烧结2h后，优化后的陶瓷膜平均孔径为249 nm，渗透率为5040 Lm−2h-1bar-1，对平均粒径为237 nm的碳墨的去除率为96.2%。本研究为高效、低成本制备高性能陶瓷膜提供了一种新方法。
A dual-layer alumina microfiltration membrane with super permeability and high selectivity was prepared by co-sintering the membrane and the support. Silica sol as sintering aid for the supports can also promote adhesion between supports and membranes. Tape-casting technique was introduced here to form the pre-membranes which were directly transfer-coated on the green support bodies. The optimum co-sintering conditions and the effects of organic agent content and membrane thickness on the membrane performance were comprehensively investigated. The optimized ceramic membrane had an average pore size of 249 nm and a water permeance of 5040 Lm−2h-1bar-1after co-sintering at 1300 °C for 2 h, which also exhibited a rejection rate of 96.2% for the carbon ink with an average particle size of 237 nm. This work provides a new method for efficient and low-cost preparation of high-performance ceramic membranes.
