Abstract
MEMBRANA DE INTERCAMBIO CATIONICO PARA CELDAS ELECTROLITICAS CON ELECTRODOS FORAMINOSOS. LA MEMBRANA ESTA CONSTITUIDA POR UN POLIMERO INTERCAMBIADOR DE CATIONES, TAL COMO UN POLIMERO FLUOCARBONADO, AL CUAL SE LE EFECTUA UN TRATAMIENTO DE EMBASTECIMIENTO MEDIANTE CHORRO DE ARENA CON PARTICULAS DE ARENA O DE CUARZO, MORDENTADO POR BOMBARDEO IONICO CATODICO, GRABADO EN RELIEVE, PRENSADO EN LA SUPERFICIE DE LA MEMBRANA O LIJADO. DE ESTA FORMA AL MENOS UNA SUPERFICIE DE LA MEMBRANA, QUE ESTA EN CONTACTO, PERO SIN UNIR, CON EL ELECTRODO DE LA CELDA, TIENE UNA MORFOLOGIA EMBASTECIDA O POROSA, EN DONDE LA DISTANCIA ENTRE LAS CRESTAS ES DE 0,5 A 50 MICROMETROS Y LA PROFUNDIDAD DE LAS IRREGULARIDADES SUPERFICIALES ES DE 0,5 A 25 MICROMETROS, Y PROPORCIONA UN AREA SUPERFICIAL AL MENOS 25% MAYOR QUE EL AREA SUPERFICIAL TOTAL DE LA MEMBRANA.
