Patent

CA 2306028

A composite hollow fiber membrane having a composite structure comprising a thin homogeneous film sandwiched between porous support layers, wherein the ratio of the oxygen permeability to the nitrogen permeability of the film is 1.1 or higher and the change of that ratio through immersion in a chemical in accordance with JIS K 7114 is within ~10 %, and which does not leak the chemical at all even when degassed.

L'invention concerne un module composite à fibres creuses présentant une structure composite comprenant un film mince homogène intercalé entre des couches de support poreuses. Le rapport entre la perméabilité à l'oxygène et la perméabilité à l'azote du film est égal ou supérieur à 1.1 et la modification de ce rapport lors de l'immersion dans un produit chimique conformément à JIS K 7114 est comprise dans une marge de +/-10 %. Cette membrane empêche toute fuite du produit chimique même après dégazage.
