Abstract

PARA PERFECCIONAR UN PROCEDIMIENTO PARA LA SEPARACION DE LAMINAS DE ALUMINIO DE LAMINAS SINTETICAS, ESPECIALMENTE DE LAMINAS DE PE, QUE PERMITA UNA RECUPERACION ECOLOGICA DEL ALUMINIO, SE PROPONE QUE LA LAMINA COMPUESTA SEA CALENTADA EN UNA SOLUCION DE AL MENOS UN 20 % DE UN ACIDO GRASO BAJO, CNH2N+1(COOH) CON N MENOR/IGUAL A 4, A ALREDEDOR DE 100 (GRADOS) C, QUE ESTE CALENTAMIENTO SEA MANTENIDO ALREDEDOR DE 10 A 20 MINUTOS, Y QUE TRAS UN ENFRIADO, LAS LAMINAS SINTETICAS SEPARADAS, SEAN SEPARADAS DE LAS LAMINAS DE ALUMINIO QUE QUEDAN ATRAS, POR LO QUE EN UN DESARROLLO DEL PROCEDIMIENTO OPTIMO, EL ENFRIADO TIENE LUGAR EN UN RECEPTACULO CERRADO, DE FORMA QUE POR EL ENFRIADO SE FORME UNA DEPRESION DE ALREDEDOR DE HASTA EL 80 % DE LA PRESION DE AIRE NATURAL.
