Abstract
PROCEDIMIENTO PARA PREPARAR UNA MEMBRANA DE POLIAMIDA.COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE PREPARA UNA SOLUCION DE COLADA QUE INCLUYE UN SISTEMA DE RESINA DE COLADA CONSTITUIDO POR UNA RESINA DE POLIAMIDA INSOLUBLE EN ALCOHOL Y UN POLIMERO QUE MODIFICA LA SUPERFICIE DE LA MEMBRANA, Y UN SISTEMA DISOLVENTE EN EL QUE DICHO SISTEMA DE RESINA DE COLADA ES SOLUBLE; SEGUNDA, SE INDUCE LA FORMACION DE NUCLEOS DE DICHA SOLUCION DE COLADA MEDIANTE LA ADICION CONTROLADA DE UN NO DISOLVENTE DE DICHO SISTEMA DE RESINA DE COLADA; TERCERA, SE EXTIENDEDICHA COMPOSICION DE COLADA SOBRE UN SUSTRATO PARA FORMAR UNA PELICULA SOBRE DICHO SUSTRATO; CUARTA, SE PONE EN CONTACTO Y SE DILUYE LA PELICULA DE DICHA COMPOSICION DE COLADA CON UN SISTEMA LIQUIDO NO DISOLVENTE DE DICHO SISTEMA DE RESINA DE COLADA; Y POR ULTIMO, SE LAVA DICHA MEMBRANA PARA SEPARAR EL DISOLVENTE Y A CONTINUACION SE SECA.
