Abstract
SE DESCRIBE UN PROCESO PARA MEJORAR LA RESISTENCIA DE LOS RADIADORES DE COBRE CARACTERIZADA POR EL FACTOR DE QUE ESTOS, TRAS ENSAMBLAR Y SOLDAR LOS COMPONENTES, SE SOMETEN A LAS SIGUIENTES OPERACIONES: LAVADO EN FRIO; DESENGRASE; ENJUAGUE CON AGUA FRIA; ENJUAGUE CON AGUA DESMINERALIZADA; FOSFATACION FILMOGENA DE LA SUPERFICIE, OPCIONALMENTE UTILIZANDO MEDIOS ELECTROLITICOS, CON UNA SOLUCION EN AGUA DESMINERALIZADA DE ACIDO FOSFORICO O DERIVADOS, ACIDO CROMICO O SALES DEL MISMO, UN AGENTE PARA REDUCIR EL CROMO HEXAVALENTE A CROMO TRIVALENTE Y RESINA POLIMERICA; ELIMINACION DEL EXCESO DE SOLUCION DE FOSFATACION FILMOGENA; SECADO; FIJACION DE LOS TUBOS DE RETORNO DE AGUA; APLICACION DE PINTURA EN POLVO; Y RECOCIDO DE LA PINTURA.A PROCESS IS DESCRIBED TO IMPROVE THE RESISTANCE OF COPPER RADIATORS CHARACTERIZED BY THE FACTOR THAT THESE, AFTER ASSEMBLING AND WELDING THE COMPONENTS, ARE SUBJECT TO THE FOLLOWING OPERATIONS: COLD WASHING; DEGREASE; RINSE WITH COLD WATER; RINSE WITH DEMINERALIZED WATER; PHILMOGENIC PHOSPHATATION OF THE SURFACE, OPTIONALLY USING ELECTROLYTIC MEANS, WITH A SOLUTION IN DEMINERALIZED WATER OF PHOSPHORIC ACID OR DERIVATIVES, A CHROMIC ACID OR SALES OF THE SAME; ELIMINATION OF EXCESS FILMOGEN PHOSPHAT SOLUTION; DRYING; FIXING OF WATER RETURN PIPES; POWDER PAINT APPLICATION; AND ANNEALING THE PAINT.
