Abstract

PROCEDIMIENTO DE OBTENCION DE UNA MEMBRANA. CONSISTE EN PREPARAR UNA SOLUCION DE UNA POLIMIDA O UNA MEZCLA DE LAS MISMAS EN ACIDO FORMICO, LA CUAL SE ALIMENTA CON APROXIMADAMENTE 1 A 7% DE POLIETILENGLICO; DICHA MEZCLA SE CALIENTA A UNOS 18<025>C Y SE VIERTE SOBRE UN SOPORTE SIENDO CONDUCIDA A TRAVES DE UN BAÑO DE PRECIPITACION Y LAVADO MOVIDO EN CONTRACORRIENTE A LA HOJA DE SOPORTE. LA MEMBRANA COAGULADA Y LAVADA ES SEPARADA DE LA HOJA DE SOPORTE DESPUES DE ABANDONAR EL BAÑO, DESPUES DE LO CUAL SE SECA; ANTES DE DICHO SECADO, LA MEMBRANA ES ESTIRADA AL MENOS EN UNA DIRECCION EN LA RELACION DE APROXIMADAMENTE 1:1,5 A 1:2,5; EL ESTIRADO TIENE LUGAR MEDIANTE UNA BARRA DE TRACCION CALENTADA UNIFORMEMENTE A 130-140<025>C.
