Abstract

La presente invención se refiere a un proceso para limpiar las superficies de contenedores de aluminio para eliminar las partículas finas de aluminio y los contaminantes orgánicos residuales sobre sus superficies, que comprende los pasos de poner la superficie del contenedor de aluminio en contacto con una solución limpiadora alcalina, acuosa, durante un periodo de tiempo suficiente para eliminar esencialmente la totalidad de las partículas de aluminio finas y los contaminantes orgánicos sobre su superficie y, después, poner la superficie del contenedor de aluminio limpia en contacto con por lo menos una solución de enjuague a base de agua acidulada, con un pH inferior a aproximadamente 2.5, para neutralizar y eliminar cualquier limpiador alcalino residual sobre la misma y cualquier película de óxido sobre la superficie, que se forme durante el paso de limpieza alcalina.The present invention relates to a process for cleaning the surfaces of aluminum containers to remove fine aluminum particles and residual organic contaminants on their surfaces, comprising the steps of bringing the surface of the aluminum container into contact with a cleaning solution. alkaline, aqueous, for a period of time sufficient to remove essentially all of the fine aluminum particles and organic contaminants on its surface, and then to bring the surface of the clean aluminum container into contact with at least one rinse solution based on acidulated water, with a pH lower than approximately 2.5, to neutralize and eliminate any residual alkaline cleaner on it and any oxide film on the surface that forms during the alkaline cleaning step.
