| 摘 要： | 以α-Al2O3为骨料,羧甲基纤维素作为成孔剂,高岭土、TiO2作为高温粘结剂和烧结助剂,采用干压成型工艺和固态粒子烧结法制备出了圆板型多孔α-Al2O3陶瓷膜支撑体(=50 mm,厚度为2 mm)。研究了成孔剂用量、高温粘结剂和烧结助剂的用量、烧结温度因素对支撑体性能的影响。结果表明,制得的支撑体孔隙率在34%以上,孔径在2.23～6.75μm,耐酸碱度在98%以上,机械强度高。

| Abstract: | Circular plate-shaped porous ceramic membrane support(diameter of 50 mm,thickness of 2 mm),with alumina as aggregate,carboxymethylcellulose as pore-fomring agent,kaolin and titanium dioxide as high temperature binder and sintering additive,was prepared by dry-pressing and solid sintering.The effects of the amount of pore-fomring agent,high temperature binder,sintering additive and sintering temperature on the properties of support were studied.The results indicate that support with porosity beyond 34%,pore size between 2.23 and 6.75 μm,acid/ alkali resistance beyond 98% and high mechanical strength was prepared. |
