| 摘要 |
A hollow fiber membrane module and its method of manufacture are disclosed wherein the module is fabricated utilizing superior hollow fiber materials, namely high molecular weight (i.e. molecular weight > 500,000 Daltons) polymers. In a preferred embodiment, the hollow fibers are fabricated from ultrahigh molecular weight polyethylene (UPE). An array of UPE hollow fiber membranes is contacted with an extrusion of molten thermoplastic polymer at a contact temperature which is higher than the UPE membrane polymer. This high temperature application of sealing polymer does not collapse or otherwise deform the lumen of the hollow fiber, while assuring that the polymer can thus be applied with sufficiently low viscosity to provide adequate penetration around the individual fibers of the array to form an integral seal thereabout.
