Abstract

ES DESCRITO AQUI UN METODO PARA PRODUCIR UNA PLANCHA DE ACERO RESISTENTE DE CORROSION, CUBIERTA DE RESINA CON PROPIEDADES CONVENIENTES PARA CUBRIR DE ELECTRODEPOSICION; EL METODO INCLUYE LOS PASOS DE, ANTERIOR AL TRATAMIENTO DE CROMADO Y CUBRIR DE RESINA, SUMERGIR LA PLANCHA DE ACERO ELECTROPLASTEADA DE CINC O ALEACION DE CINC EN UN BAÑO ACIDO QUE CONTIENE AL MENOS UN MIEMBRO SELECCIONADO DEL GRUPO QUE CONSTA DE ACIDO SULFURICO, ACIDO CLORICO, ACIDO FOSFORICO, ACIDO BORICO Y ACIDO NITRICO Y SUS SALES, Y TENIENDO UN VALOR PH MAS PEQUEÑO QUE 6, INCLUSIVE, PARA QUITAR UNA CAPA SUPERFICIAL DE LA ELECTOPLASTIA EN DICHA PLANCHA DE ACERO, POR LO CUAL ACTIVAR LA SUPERFICIE CHAPADA EN TAL FORMA PARA MEJORAR LA CALIDAD DEL SIGUIENTE TRATAMIENTO DE CROMADO. VENTAJOSAMENTE, EL METODO ADEMAS INCLUYE EL PASO DE ABRAZAR LA SUPERFICIE ELECTROPLATEADA CON UNA ESCOBILLA O RODILLO QUE CONTIENE GRANOS ABRASIVOS FINOS DE 200 O UN NUMERO MAS ALTO PARA QUITAR DICHA CAPA SUPERFICIAL SIMULTANEAMENTE CON, O SEPARADAMENTE DE LA INMERSION EN EL BAÑO ACIDO.
