摘要
针对钛白粉悬浮体系的分离回收 ,根据理论模型对陶瓷膜的结构 (膜平均孔径 )进行了优化设计 ,并采用粒子烧结法制备了所设计孔径的氧化铝陶瓷膜 .通过与其他陶瓷膜的过滤实验对比表明 ,模型优化设计并制备得到的陶瓷膜具有较高的过滤通量 ,孔径与通量关系计算值与实验结果有较好的一致性 。
On the basis of the developed microfiltration model, membrane pore size was optimized to filter the particle suspensions of titanium pigment. The optimized Al 2O 3 ceramic membrane was prepared by state particle sintering method and characterized by SEM and the gas bubble pressure method. The prepared membrane was superior to commercial membranes and the model calculation showed good agreement with the experimental results. The method of application-oriented ceramic membranes design was basically completed.
