Abstract

LA PRIMERA ETAPA DE ESTE PROCEDIMIENTO CONSISTE EN PONER EN CONTACTO LAS SUPERFICIES CON UNA SOLUCION QUE TIENE UN CONTENIDO DE AL MENOS DOS IONES METALICOS DISTINTOS Y POLIVALENTES Y DE FORMADORES DE COMPLEJOS EN UNA CANTIDAD QUE PERMITE QUE LOS IONES METALICOS POLIVALENTES SE MANTENGAN EN SOLUCION Y QUE POSEE UN PH MAYOR O IGUAL QUE 11. LA ETAPA SIGUIENTE CONSISTE EN UN ACLARADO POSTERIOR CON UNA SOLUCION QUE CONTIENE ALUMINIO, CIRCONIO Y FLUORUROS Y QUE TIENE UN PH MENOR QUE 5. LAS MODALIDADES PREFERENTES DE ESTE PROCEDIMIENTO CONSISTEN EN MANTENER LA CONCENTRACION TOTAL DE AL + ZR + F EN UN VALOR ENTRE 0,1 Y 8,0 G/L, PREFERENTEMENTE ENTRE 0,2 Y 5,0 G/L, Y EN FIJAR LA RELACION MOLECULAR AL: ZR: F EN (0,15 A 8,0): 1: (5 A 52) Y/O EN (0,15 A 0,67): 1: (5 A 7). LA DURACION DEL TRATAMIENTO Y LA TEMPERATURA SON, RESPECTIVAMENTE, DE 1 A 120 SEGUNDOS DE 20 A 50 C. ESTE PROCEDIMIENTO SE APLICA PROVECHOSAMENTE COMO PRETRATAMIENTO PARA UN POSTERIOR LACADO, RECUBRIMIENTO CON LAMINADOS O REVESTIMIENTOS ADHESIVOS.
