Abstract

LA INVENCION PREVE PARA EL ACLARADO DE SUPERFICIES DE ALUMINIO O DE ALEACIONES DE ALUMINIO CON CAPAS DE CONVERSION OBTENIDAS CON SOLUCIONES A BASE DE IONES DE TITANIO, CIRCONIO Y/O HAFNIO, EL USO DE SOLUCIONES ACUOSAS QUE CONTIENEN ALUMINIO, CIRCONIO Y FLUORUROS Y QUE TIENEN UN PH MENOR O IGUAL QUE 5. SE ACLARA, PREFERENTEMENTE, CON SOLUCIONES QUE TIENEN UNA CONCENTRACION TOTAL DE AL + ZR + F ENTRE 0,1 Y 8,0 G/L, ESPECIALMENTE DE 0,2 Y 5,0 G/L, Y UNA RELACION MOLECULAR AL: ZR: F DE (0,15 A 8,0): 1: (5 A 52), ESPECIALMENTE DE (0,15 A 2,0): 1: (5 A 16), Y ESPECIALMENTE PROVECHOSA DE (0,15 A 0,67): 1: (5 A 7). LA APLICACION DE LAS SOLUCIONES DE ACLARADO QUE HAN DE TENER UNA TEMPERATURA DE 20 A 80 C, PREFERENTEMENTE DE 20 A 50 C, SE LLEVA A CABO DURANTE 1 A 30 SEGUNDOS. ESTE PROCEDIMIENTO SIRVE SOBRE TODO PARA EL PRETRATAMIENTO DE SUPERFICIES PREVISTAS PARA UN POSTERIOR LACADO, RECUBRIMIENTO DE LAMINADOS O DE REVESTIMIENTOS ADHESIVOS.
