摘要

Abstract

A process based on the suspended particle technique was used to deposit Al2O3 micro-filtration membranes on α-Al2O3 support

α-Al2O3 supports with four different pore sizes were analyzed.The effects of surface roughness

pore size of support and matching condition between support pore size and suspension particle size on the integrity of micro-filtration membranes were discussed.The results showed that an integral crack-free membrane could be made with smooth support surface and fine matching between suspension particle size and support pore size.The test data showed that the limiting ratio between support pore size and suspension particle size was 10.When the ratio was more than 10

the membrane thus made would have surface cracks

wide distribution of pore size and small porosity.When the ratio was less than 10

the membrane thus made would have crack free surface

narrow of distribution of pore size and large porosity.
