Microporous hollow fiber membranes from perfluorinated thermoplastic polymers

   
   

High flux porous hollow fiber membranes are produced from perfluorinated thermoplastic polymers by extruding heated solution of the polymer having a lower critical solution temperature directly into a cooling bath to form the porous membrane by liquid-liquid phase separation. Extrusion can be conducted either vertically or horizontally.

Werden poröse hohle Fasermembranen des hohen Flusses aus perfluorinated thermoplastischen Polymer-Plastiken durch verdrängende geheizte Lösung des Polymer-Plastiks produziert, das eine niedrigere kritische Lösung Temperatur direkt in ein abkühlendes Bad, um die poröse Membrane zu bilden durch Flüssigkeit-Flüssigkeit Phase Trennung hat. Strangpresßling kann vertikal oder horizontal geleitet werden entweder.
