Title:
METHOD FOR THE CONTINUOUS PRODUCTION OF TUBULAR MEMBRANES
Document Type and Number:
WIPO Patent Application WO2004035183
Kind Code:
A3
Abstract:
Disclosed is a method for continuously producing tubular composite or compound membranes comprising a porous substructure (support layer) which essentially provides the membrane with mechanical resistance, and a layer that is applied thereupon, is made of a material having a different chemical property, and substantially provides the membrane with separating properties (separation layer). According to the inventive method, a corresponding flat composite membrane is shaped into a tube in the longitudinal direction or in a spiraling manner, the separation layer facing inward, whereupon said tube is welded or bonded edge to edge or in an overlapping manner, a strip of a solidifying sealing material is applied to the edge seam or the interior overlapping area from inside, and the sealing material is solidified.
