PROCESS FOR MANUFACTURING A HOLLOW FIBRE MEMBRANE |
摘要 |
<p>The present invention relates to a process for manufacturing a hollow fibre membrane having a supporting layer and a separating layer, said process comprising: (a) extruding a spinning composition comprising a first polymer and a solvent for the first polymer through an inner annular orifice of a hollow-fibre die; (b) co-extruding a composition comprising an organic nucleophilic reagent and a mixtures of a solvent and a non-solvent for the first polymer, wherein the composition is either extruded through a central annular orifice of the hollow-fibre die or through an outer annular orifice of a hollow-fibre die; and (c) passing the hollow-fibre through a coagulation bath. The hollow fibre membrane according to the present invention can be used in gas separation processes, vapour separation processes and liquid filtration processes.</p> |
