【 摘 要 】

In order to prepare the ceramic ultrafiltration membrane with high-performance, the modification method of nano-metal oxides was chosen. The 19 channel porous ceramic membrane and the ZrCl4 were chosen as the raw materials. The effects of ZrCl4 concentration and modification times on the pore-size, permeability and structure of ceramic membrane were studied in detalis. The result shows that the nano-ZrO2 was generated on the surface of the ceramic membrane after being modified and sintered. It can reduce the pore-size and the surface roughness of the ceramic membrane. Meawhile, this method can improve the permeability. Consequently, the ceramic ultrafiltration membrane has the pore-size of 75nm and the permeability of 1010.12L/m2•h•bar after sintering at 600°C for 2h with the optimized concentration of modify solution was 10g/L and the modified times was twice.
