Abstract
Un particulado removedor de oxígeno bien disperso compuesto en una matriz polimérica. La formula del removedor de oxígeno consta de polvo de hierro con tamanos medio de particular entre 1-25 mm y revestido previamente con por lo menos uno o más compuestos en polvo activantes y acidificantes, generalmente en forma de sales solidas orgánicas e inorgánicas de metales alcalinos y metales de tierra alcalina, tales como cloruro de sodio y bisulfato de sodio. El particulado de hierro previamente revestido se dispersa en una resina polimérica utilizando un método convencional de procesamiento de fusion tal como la extrusion de doble tornillo. El compuesto removedor de oxígeno se mezcla con pellets poliméricos en estado solido con anterioridad a la fusion. Los pellets de resina polimérica y el polvo de hierro revestido se tratan preferentemente con un surfactante en estado seco para ayudar a la dispersion del polvo de hierro/sal con los pellets de resina. Los compuestos extruidos de la fusion se peleltizan y se mantienen en estado seco para evitar la activacion prematura.A well dispersed particulate oxygen remover composed in a polymer matrix. The oxygen remover formula consists of iron powder with average sizes of particular between 1-25 mm and previously coated with at least one or more activating and acidifying powder compounds, generally in the form of solid organic and inorganic alkali metal salts. and alkaline earth metals, such as sodium chloride and sodium bisulfate. The previously coated iron particulate is dispersed in a polymeric resin using a conventional method of fusion processing such as double screw extrusion. The oxygen remover compound is mixed with polymeric pellets in solid state prior to fusion. The polymeric resin pellets and the coated iron powder are preferably treated with a dry surfactant to aid in the dispersion of the iron / salt powder with the resin pellets. The extruded compounds of the fusion are pelleted and kept dry to prevent premature activation.
