METHOD FOR MANUFACTURING SHEET-LIKE SEPARATION MEMBRANE |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a sheet-like separation membrane which is capable of manufacturing the sheet-like separation membrane having uniform separation properties at a high speed. <P>SOLUTION: The method for manufacturing a sheet-like separation membrane forming a microporous layer on a porous substrate includes: a step of membrane production solution coating step of coating the membrane production solution wherein a polymer is dissolved in a solvent medium on the porous substrate; a congealed liquid coating step of coating a congealed liquid on a coagulated microporous layer on which the membrane production solution is coated, by a liquid membrane drop method; and a solvent removing step of removing the solvent from the coagulated microporous layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
