| Compared with traditional polymer separation membrane materials, ceramic membrane materials with a large number of asymmetric through micro pore structures are widely used in the fields of liquid-solid separation, gas-solid separation, water treatment, energy conservation and environmental protection because of their high separation efficiency, strong chemical corrosion resistance and high temperature resistance. Aiming at the development of ceramic membrane materials, the material system of ceramic membrane was introduced minutely and the advantages and disadvantages of different preparation methods were compared in this paper. Moreover, the paper has summarized the types and application fields of ceramic membrane materials currently, as well as analyzed the research status and existing problems of ceramic membrane both domestic and international. Suggestions were put forward from market demand, industrial scale and performance improvement, which has certain guiding significance for the development of ceramic membrane industry. |
