(ES) COMPOSICIÓN Y PROCEDIMIENTO DE OBTENCIÓN DE TABLETAS DE Mn
(FR) COMPOSITION ET PROCÉDÉ D'OBTENTION DE PASTILLES DE MN
Abstract
(EN) The invention relates to a composition for manufacturing Mn tablets, characterized in that it includes: (a) between 70% and 99.5% by weight of Mn powder; (b) a first powder binder chosen from at least one organic polymer that is insoluble in water and at least one organic polymer that is soluble in water, or a mixture of the two, wherein said first binder is not a wax. The invention likewise relates to a method for producing said composition and to the use thereof as Mn tablets in the casting of metals.
(ES) Composición y procedimiento de obtención de tabletas de Mn La presente invención se refiere a una composición para la fabricación de tabletas de Mn caracterizada por que comprende: (a) polvo de Mn en un porcentaje comprendido entre un 70% y un 99.5%en peso de la composición; (b) un primer aglomerante en polvo seleccionado entre al menos un polímero orgánico insoluble en agua y al menos un polímero orgánico soluble en agua, o una mezcla de ambos, donde dicho primer aglomerante no es una cera. Es asimismo objeto de la invención un procedimiento para la obtención de dicha composición y su uso como tabletas de Mn en la colada de metales.
(FR) L'invention concerne une composition et un procédé d'obtention de pastilles de Mn. La présente invention concerne une composition pour la fabrication de pastilles de Mn caractérisée en ce qu'elle comprend: (a) une poudre de Mn selon un pourcentage compris entre 70% et 99% en poids de la composition; (b) un premier agglomérant en poudre sélectionné parmi au moins un polymère organique insoluble dans l'eau et au moins un polymère organique soluble dans l'eau, ou un mélange des deux, ledit premier agglomérant n'étant pas une cire. L'invention concerne également un procédé pour l'obtention de ladite composition et son utilisation comme pastilles de Mn dans la coulée de métaux.
