Abstract

DEBIDO A SU CAPACIDAD DE RESISTENCIA TERMICA Y QUIMICA Y AL SER INOFENSIVA EN EL CONTACTO CON ALIMENTOS Y MATERIAS FARMACEUTICAS SE REPRESENTAN PREFERENTEMENTE UN MATERIAL DE FILTRACION PARA MEMBRANAS A BASE DE POLISULFONAS AROMATICAS. PERO ESTAS SON HIDROFOBAS Y ELLAS PUEDEN SER HIDROFILADAS ANTES DE SU EMPLEO. HASTA AHORA METODOS DE HIDROFILACION NO BASTAN, PARA OBTENER Y MANTENER LA HIDROFILIDAD DE LA MEMBRANA Y TAMBIEN VARIAS ESTERILIZACIONES. CON EL NUEVO PROCEDIMIENTO DEBER PROCURARSE A LA MEMBRANA CON UNA HIDROFILIA PERMANENTE EN CONDICIONES DE ESTERILIZACION. EN UNA ETAPA DE TRATAMIENTO POSTERIOR LA MEMBRANA A BASE DE SULFONA AROMATICA ANTES O DESPUES DEL SECADO SE CONDUCE A UN BAÑO DE IMPREGNACION DE POLIVINILOPIRROLIDONA, UN COPOLIMERO DE VINILOPIRROLIDONA Y UNO O VARIOS MONOMEROS HIDROFOBOS Y PEROXIDISULFATO, DESPUES SE CALIENTA ENTRE 70 Y 150 C Y DE NUEVO SE ENFRIA. ASI LA MEMBRANA TRATADA PERMANECE TAMBIEN DESPUES DE LA ESTERILIZACION HUMEDECIBLE ESPONTANEAMENTE CON AGUA. LA MEMBRANA HIDROFILA PERMANENTE A BASE DE POLISULFONA AROMATICA Y PROCEDIMIENTO PARA SU PRODUCCION.
