文摘

The zeolite membrane is obtained by non-hydrothermal combined dip-coating method. The non-crystal geopolymer gel transformed into NaA zeolite after cured at 60 °C. The vacuum inhalation repair method improved the separation factor of membrane. The repair method is suitable for membranes with mesopore or macropore defects.
