摘　　要：采用固态粒子烧结法和浸拉提渍工艺研制出α-Al2O3平板式陶瓷微滤膜,探讨涂膜液中固含量对膜孔径及纯水通量的影响,并研究涂层工艺及烧成制度对膜形成的作用。同时对微滤膜的孔径大小及分布,膜孔隙率、纯水通量及抗弯强度等性能进行表征。实验结果表明,制备出平均孔径为0.7μm的平板陶瓷膜,其具有表面性质连续完整、孔径分布窄以及机械强度大的特点。α-Al2O3 flat ceramic micro-filtration membrane was prepared by solid state sintering and dip-coating method. The influence of solid content in the coating liquid of membrane to pore size and pure water flux was explored, and the effect of the coating process and sintering system on the membrane formation was analyzed. Characterizations of the micro-membrane such as the pore size and pore size distribution,membrane porosity,pure water flux and flexural behavior were studied. The results indicated that membrane with porosity beyond 30%,average pore size 0.7μm, continuous complete surface properties,narrow pore distribution and high mechanical strength was prepared.
