Abstract

SE PREPARAN MAMBRANAS DE MATERIALES COMPUESTOS DEPOSITANDO UNA CAPA DE SEPARACION SOBRE UNA CAPA SOPORTE ASIMETRICA. LA CAPA DE SEPARACION TIENE UNA SELECTIVIDAD IGUAL A O MAYOR QUE LA DEL MATERIAL DE LA CAPA SOPORTE ASIMETRICA PARA UNA SEPARACION DE GAS DESEADA. LA CAPA SOPORTE PREFERENTEMENTE SE PREPARA EN FORMA NO ASIMETRICA, Y SE EXPONE A UNA TEMPERATURA ELEVADA PROXIMA A LA TEMPERATURA DE TRANSICION VITREA DEL MATERIAL DE LA CAPA SOPORTE, EN CONDICIONES DE NO HINCHAMIENTO QUE MODIFIQUEN SU ESTRUCTURA PARA CREAR ASIMETRIA DE LA MISMA, ANTES O DESPUES DE LA DEPOSICION DE LA CAPA DE SEPARACION Y PARA AUMENTAR SU RESISTENCIA A LA COMPACTACION Y A LA PRESION DE DESMORONAMIENTO. TALES PROPIEDADES SE CONSIGUEN ADECUADAMENTE DE MODO REPETIBLE MEJORANDO LA UNIFORMIDAD Y PRECISION DE LA CAPA SOPORTE TRATADA Y DE LAS MEMBRANAS DE MATERIALES COMPUESTOS OBTENIDAS A PARTIR DE AQUEL, PARA USAR EN OPERACIONES DE SEPARACION DE GAS.
