Abstract

METODO PARA FABRICAR UN IMAN PERMANENTE AGLOMERADO. COMPRENDE: A) ENFRIAR A LAS PARTICULAS DE ALEACION TIERRA RARA-HIERRO-BORO CON UNA RESINA EPOXIDICA SIN CURAR EN FORMA DE POLVO SECO; B) MEZCLAR A LAS PARTICULAS ENFRIADAS CON UN CATALIZADOR DE IMIDAZOL PARA RESINA INACTIVO A LA TEMPERATURA DE MEZCLA; C) PRENSAR A LA MEZCLA EN UNA PIEZA COMPACTA QUE TENGA UN 70% DE LA DENSIDAD DE LA ALEACION; D) CALENTAR A LA PIEZA COMPACTA DURANTE TEMPERATURA Y TIEMPO SUFICIENTE, PARA FUNDIR A LA RESINA EPOXIDICA QUE RECUBRA Y LLENE LOS INTERSTICIOS ENTRE LAS PARTICULAS DE ALEACION Y ACTIVAR AL CATALIZADOR QUE CURA A LA RESINA EPOXIDICA Y E) MAGNETIZAR A LAS PARTICULAS DE ALEACION COMPACTADAS EN UN CAMPO MAGNETICO APLICADO, PARA FORMAR UN IMAN DURADERO Y RESISTENTE. LAS PARTICULAS DE ALEACION ESTAN CONSTITUIDAS POR CINTA CENTRIFUGADA EN FUSION Y TRITURADA DE ALEACION DE PRASEODIMIO-HIERRO-BORO; EL CATALIZADOR DE IMIDAZOL ES UN IMIDAZOL SUSTITUIDO EN LA POSICION 2 CON UN GRUPO ALQUILO Y LA RESINA EPOXIDICAES UN POLIGLICIDIL-ETER DE UN POLIFENOL-ALCANO QUE TIENE UNA TEMPERATURA DE TRANSICION VITREA DE 150JC.
