Abstract

PARA EL TRATAMIENTO DE CHAPAS DE ACERO CINCADAS ELECTROQUIMICAMENTE POR UNA SOLA CARA SE PONE EN CONTACTO LA CARA NO CINCADA CON UN LIQUIDO ACUOSO DE DECAPADO. EL LIQUIDO ACUOSO DE DECAPADO CONTIENE UN ACIDO HIDROXICARBONICO Y UN COMPUESTO PEROXO. EN EL PROCEDIMIENTO SE DESPRENDE LOS OXIDOS RESISTENTES A LA ACCION DEL EXTERIOR OBTENIENDOSE CHAPAS DE ACERO NO CRUZADAS CON BANDAS DE COLOR AMARILLO O MARRON QUE DAN LUGAR A CHAPAS FINAS CINCADAS ELECTROLITICAMENTE EN UNA SOLA CARA CON EL TRATAMIENTO DEL BAÑO DE DECAPADO. LAS SUPERFICIES METALICAS NO CINCADAS SE PUEDEN PASIVAR SIMULTANAMENTE CON LAS OTRAS CARAS.
