Abstract
Unas partículas para capturar oxígeno bien dispersas combinadas en una matriz de polímero. La formulación del material para capturar oxígeno comprende polvo de hierro con un tamaño medio particular de entre 1-25 um y pre-recubierto con al menos uno o más de los compuestos en polvo para activación y acidificación, generalmente en forma de sólidos orgánicos y sales inorgánicas de metales alcalinos y alcalinotérreos tales como cloruro de sodio y bisulfato de sodio. Las partículas de hierro pre-recubiertas se dispersan en una resma de polímero utilizando un método de fusión convencional como la extrusión doble tornillo. El compuesto de material para capturar oxígeno se mezcla con gránulos de polímero en estado sólido antes de la fusión. Los gránulos de resma de polímero y el polvo de hierro recubierto son preferiblemente tratados con un agente surfactante en estado seco para ayudar a dispersar el polvo de hierro/sal con los gránulos de resma. Los compuestos extruidos por fusión se granulan y mantienen en estado seco para evitar la activación prematura.Particles to capture well dispersed oxygen combined in a polymer matrix. The formulation of the material for capturing oxygen comprises iron powder with a particular average size between 1-25 um and pre-coated with at least one or more of the powdered compounds for activation and acidification, generally in the form of organic solids and salts inorganic alkali and alkaline earth metals such as sodium chloride and sodium bisulfate. Pre-coated iron particles are dispersed in a polymer ream using a conventional fusion method such as double screw extrusion. The compound of oxygen capture material is mixed with solid-state polymer granules before melting. The polymer ream granules and the coated iron powder are preferably treated with a dry surfactant to help disperse the iron / salt powder with the ream granules. The melt extruded compounds are granulated and kept dry to prevent premature activation.
