Abstract

UNA FIBRA POLISULFONICA HUECA PENSADA PARA UNA MEMBRANA SELECTIVAMENTE TRANSMISIVA QUE CONTIENE UN POLIMERO HIDROFILICO ENTRECRUZADO EN UNA FORMA INDISOLUBLE EN AGUA (POR EJEMPLO POLIVINILPIRROLIDONA) Y QUE SE UTILIZA A MODO DE UN AGUA QUE CONTIENE HIDROGEL. UN METODO PARA LA PRODUCCION DE UN MODULO CON MEMBRANA QUE CONSISTE EN CENTRIFUGAR UNA FIBRA HUECA UTILIZANDO UNA SOLUCION EN ROTACION QUE CONTENGA UNA RESINA POLISULFONICA Y UN POLIMERO HIDROFILICO, HUMEDECER LA FIBRA HASTA QUE TENGA UN CONTENIDO DE HUMEDAD POR ENCIMA DEL SATURADO Y, A CONTINUACION, MANTENIENDO LA CONDICION DE HUMEDECIDA, SOMETER A LA FIBRA A LOS PROCESOS DE ENTRECRUZAMIENTO INDUCIDO LA RADIACION Y EL MOLDEO DEL MODULO, LLEVANDOSE A CABO ESTOS PROCESOS EN CUALQUIER ORDEN.
