SEPARATION MEMBRANE MANUFACTURING METHOD |
摘要 |
Provided is a separation membrane manufacturing method capable of easily manufacturing a dense separation membrane. The separation membrane manufacturing method comprises a membrane forming step of forming a separation membrane precursor 3 containing a separation membrane precursor solution on the surface of cells formed in a porous monolith substrate 1; and a drying step of performing ventilation drying by passing hot air 15 through the cells 2 having the separation membrane precursor 3 in the monolith substrate 1 to dry the separation membrane precursor 3. During the ventilation drying in the drying step, the temperature of the monolith substrate 1 having the separation membrane precursor 3 is raised to 90°C within 15 minutes from the start of the passing of the hot air 15 at such a rate of temperature rise that an average rate of temperature rise is 7°C/min or more from the start of the passing of the hot air until the temperature reaches 90°C. |
