Abstract

PROCEDIMIENTO PARA PROTEGER SUPERFICIES DE ACERO DE LA ACCION OXIDANTE DE LA ATMOSFERA MEDIANTE LA FORMACION DE UNA CAPA PROTECTORA DE FOSFATO QUELATADA INTERMEDIA O EXTERNA. CONSISTE EN TRATAR LA SUPERFICIE A PROTEGER CON UNA SOLUCION ACUOSA QUE COMPRENDE DE 15 AL 30 POR 100 EN PESO DE GLUCOSIDOS DE ACIDO PIROGALICO Y/O DE ACIDO ELAGICO; DEL 1,1 AL 2 POR 100 EN PESO DE FOSFATOS DE METALES DE TRANSICION BIVALENTES; DEL 0,5 AL 1 POR 100 EN PESO DE FORMALDEHIDO, Y DEL 18 AL 32 POR 100 DE DISOLVENTES ORGANICOS HIDROXILADOS MISCIBLES CON AGUA. LOS GLUCOSIDOS DE ACIDO PIROGALICO Y/O DE ACIDO ELAGICO FORMAN UN QUELATO INSOLUBLE CON LOS IONES DE HIERRO QUE SE PRODUCEN AL TRATAR LA SUPERFICIE CON UNA CONCENTRACION DEL 2 AL 3 POR 100 EN PESO DE ACIDO FOSFORICO, MIENTRAS SE VERIFICA EL ATAQUE DE DICHA SUPERFICIE POR LA PRESENCIA DE UN 7 AL 12 POR 100 DE NITRATOS DE METALES BIVALENTES. LOS FOSFATOS DE METALES DE TRANSICION BIVALENTES GENERAN, EN CONTACTO CON LA SUPERFICE DEL METAL, ACIDO FOSFORICO.
