Abstract
PROCEDIMIENTO PARA ELIMINAR EL RECUBRIMIENTO ORGANICO DE LA CHATARRA DE ALEACION DE ALUMINIO. CONSISTENTE EN LA DEPOSICION DE SALES FUNDENTES SOBRE LA SUPERFICIE DE LA CHATARRA ANTES DE ELIMINAR EL RECUBRIMIENTO POR COMBUSTION. SE UTILIZA UNA DISOLUCION ACUOSA, QUE CONTIENE AL MENOS 4 POR 100 DE MEZCLA FUNDENTE, CONSTITUIDA POR SALES DE HALOGENUROS DE METAL, PREFERIBLEMENTE ENTRE 40-60 POR 100 DE KCL Y 60-40 POR 100 DE NACL, CON ADICION DE NAF Y-O KF EN UNA CANTIDAD TOTAL DE HASTA 3 POR 100. LA APLICACION DE LA DISOLUCION SE EFECTUA PULVERIZANDO LA CHATARRA EN FORMA DE FRAGMENTOS SEPARADOS, QUE SE SOMETEN, DESPUES DE SECADOS, A COMBUSTION EFECTUADA A UNA TEMPERATURA ENTRE 400 A 500 GRADOS CENTIGRADOS.
