METHOD FOR PRODUCING AN INTEGRAL- ASYMMETRIC HOLLOW -FIBRE POLYMER MEMBRANE CONSISTING OF AN AMPHIPHILIC BLOCK COPOLYMER THE ,HOLLOW- FIBRE MEMBRANE OBTAINED AND THE USE THEREOF |
摘要 |
<p>The invention relates to a method using a dry/wet spinning method for producing a self- supporting integral asymmetric hollow -fibre polymer membrane (16) having an isoporous outer skin, a porous inner skin and a sponge- like inner structure. The invention further relates to an integral asymmetric hollow- fibre polymer membrane (16) , a filtration module and a use. The method according to the invention comprises the following method steps: production of a polymer solution having at least one solvent , in which at least one amphiphilic block copolymer having at least two different polymer blocks is dissolved; pressing the polymer solution through a spinneret (2) formed as a hollow- core nozzle or multiple hollow core nozzle to form a hollow fibre (12) , in the centre of which a liquid column is spun, which consists of a precipitant having reduced precipitation activity; and after passing through a precipitation section (13) in an atmosphere , immersing the spun hollow- fibre (12) in a precipitation bath (14) to form the hollow fibre polymer membrane (16).</p> |
