Abstract

SEPARACION DEL ACIDO DE BAÑOS CATODICOS PARA RECUBRIMIENTO POR INMERSION, EN LA CUAL SE RECUBREN SUSTRATOS CONDUCTORES DE ELECTRICIDAD CON RESINAS CATIONICAS EN FORMA DE DISPERSION ACUOSA, DE MANERA QUE AL MENOS UNA PARTE DEL BAÑO DE RECUBRIMIENTO POR INMERSION SE SOMETE A UNA ULTRAFILTRACION, Y LA MEMBRANA DE ULTRAFILTRACION RETENGA LA RESINA CATIONICA FORMANDOSE UN ULTRAFILTRADO QUE CONTIENE AGUA, DISOLVENTE, SUSTANCIAS DE BAJO PESO MOLECULAR E IONES. AL MENOS UNA PARTE DEL ULTRAFILTRADO SE DEVUELVE AL BAÑO DE INMERSION, Y PREVIAMENTE, AL MENOS UNA PARTE DEL ULTRAFILTRADO SE SOMETE A UNA ELECTRODIALISIS ESPECIAL.
