Abstract
SE ATACAN QUIMICAMENTE SUSTRATOS DE MULTIPLES CAPAS QUE CONTIENEN COBRE Y SE ELIMINAN REFUERZOS O COLAS, FORMADOS EN LOS ORIFICIOS PASANTES CHAPADOS EN ESTOS SUSTRATOS, SIMULTANEAMENTE, POR TRATAMIENTO CON UNA COMPOSICION ACUOSA QUE INCLUYE APROXIMADAMENTE EL 25% DE ACIDO NITRICO. LA MISMA COMPOSICION ACUOSA SE PUEDE USAR PARA ELIMINAR COLAS FORMADAS DURANTE EL TRATAMIENTO DE DICHOS SUSTRATOS CON OTROS AGENTES DE ATAQUE QUIMICO.
