Abstract

METODO Y DISPOSICION PARA MEJORAR LA DISPERSION DE PARTICULAS MAGNETICAS EN UN LIQUIDO CONSTITUIDO POR RESINA Y DISOLVENTE PARA FORMAR UNA COMPOSICION DE REVESTIMIENTO, COMPRENDIENDO EL METODO SOMETER LA COMPOSICION DE REVESTIMIENTO A UN CAMPO MAGNETICO DE PARAMETROS OPTIMOS CON RELACION A LA FRECUENCIA, INTENSIDAD DE CAMPO Y DURACION, DE TAL MODO QUE SE OBTENGA UNA DISTRIBUCION HOMOGENEA DE LAS PARTICULAS MAGNETICAS EN EL LIQUIDO. LA DISPOSICION COMPRENDE DOS ELECTROIMANES (1, 2) QUE FORMAN UN ANGULO ENTRE SI Y QUE ESTAN DISPUESTOS ALREDEDOR DE UN TUBO (3) QUE LLEVA LA COMPOSICION DE REVESTIMIENTO. EL INVENTO ES APLICABLE A LA PRODUCCION DE SOPORTES DE GRABACION MAGNETICOS, TALES COMO DISCOS Y CINTAS MAGNETICAS.
