Abstract
2.1.DADO QUE LAS MEMBRANAS DE FILTRACION SIMETRICAS MUESTRAN SOLAMENTE UNA CAPACIDAD DE CARGA DE SUCIEDAD RELATIVAMENTE REDUCIDA, EN LAS APLICACIONES DE FILTRO SE UTILIZAN POR ELLO TIEMPOS DE PARADA MAS GRANDES CON PREFERENCIA EN LAS MEMBRANAS DE MICROFILTRACION ASIMETRICAS. ESTAS ESTAN CONFIGURADAS O BIEN DE FORMA INTEGRAL, CON UNA CAPA DE SEPARACION RELATIVAMENTE DELGADA, O BIEN COMO MEMBRANAS DE COMPOSITE. LAS MEMBRANAS INTEGRALES, ASIMETRICAS SON PLEGADAS EN EL MONTAJE EN LAS APLICACIONES DE MONTADO, SOPORTANDO EN SUS BORDES DE ROTURA INCLUSO DAÑOS, CON LO CUAL SE MODIFICA SU POROSIDAD. EN MEMBRANAS DE COMPOSITE SE INVIERTE CON ELLO EN LA ESTERILIZACION LA DISPOSICION DE CAPAS DE MEMBRANA DE EXTERIORES DE FORMA SENCILLA. ESTA DESVENTAJA DEBE SER EVITADA TAMBIEN EN LA NUEVA MEMBRANA. 2.2.DE ACUERDO CON LA INVENCION SE ELABORA LA NUEVA MEMBRANA DE TAL MODO, QUE EN UN PROCEDIMIENTO DE INVERSION DE FASE SE DISPONE DE MULTIPLES CAPAS CON VISCOSIDAD QUE SE REDUCE HACIA LAS CAPAS SUPERIORES PARA LA SOLUCION DE COLADA RESPECTIVAMENTE A PARTIR DE LA SEPARACION DE FASE EN EL PROCESO DE FLUIDO DE FUSION DE CAPAS DISPUESTAS UNA SOBRE OTRAS. CON ELLO SE OBTIENE UNA MEMBRANA DE FILTRACION INTEGRAL, ESTRATIFICADA, MICROPOROSA, CON UNA ESTRUCTURA DE POROS SIMETRICOS HOMOGENEOS PARA LAS CAPAS DE FILTRADO TERMINAL Y UNA ESTRUCTURA DE PORO ABIERTO PARA LAS CAPAS DE FILTRADO PREVIO QUE SE ENCUENTRAN POR DEBAJO DE ELLAS. 2.3.LAS NUEVAS MEMBRANAS SE UTILIZAN TAMBIEN CON DIAMETROS DE PORO PEQUEÑO PARA SU MONTAJE EN APLICACIONES DE FILTRO, SIN CONFIGURACION DE DAÑOS EN LOS BORDES DE ROTURAS CUANDO SE PLIEGAN Y MUESTRAN UNA INCLINACION DE BLOQUEO REDUCIDA CON ALTA CUOTA DE PRODUCCION DE FILTRADO.
