Abstract
SE PROPORCIONA UNA MEZCLA MAGNETICA FLEXIBLE QUE ESTA HECHA DE PARTICULAS MAGNETICAS DE FERRITA DE ALTA ENERGIA EN UN AGLUTINANTE POLIMERICO FLEXIBLE RESISTENTE A LAS ALTAS TEMPERATURAS Y OLEORRESISTENTE. EL SISTEMA AGLUTINANTE ES PREFERENTEMENTE UN CAUCHO NITRILICO (HSN) ALTAMENTE SATURADO, O UNA ALEACION POLIMERICA DEL MISMO DONDE UN HSN ES EL POLIMERO PRINCIPAL CONTENIENDO POLIMEROS DE ALEACION, O ADITIVOS QUE SON COMPATIBLES CON EL PROCESAMIENTO, CURADO POSTERIOR DE HACES ELECTRONICOS Y COMPORTAMIENTO FINAL DEL PRODUCTO. EL AGLUTINANTE DEL SISTEMA ESTA ALTAMENTE CARGADO, GENERALMENTE DE 55 A 65 PORCENTAJE EN VOLUMEN, CON PARTICULAS DE FERRITA DE GRAN ENERGIA, ES DECIR, PARTICULAS DE FERRITA DE BARIO O ESTRONCIO, QUE PUEDEN DAR ORIGEN A IMANES ENLAZADOS, CON UN PRODUCTO MAXIMO DE ENERGIA DE, AL MENOS, 1''0 MEGAGAUSOS-OERSTEDIOS, UNA REMANENCIA MAGNETICA, BR, DE AL MENOS 2000 GAUSSIOS, UNA FUERZA COERCITIVA, HC, DE AL MENOS 1800 OERSTEDIOS, Y UNA COERCITIVIDAD INTRINSECA, HCI, DE AL MENOS2000 OERSTEDIOS. EL PROCEDIMIENTO PARA LA PRODUCCION DE ESTE SISTEMA IMPLICA LA MEZCLA DEL SISTEMA AGLUTINANTE Y PARTICULAS DE FERRITA, ORIENTANDOSE LAS PARTICULAS DE FERRITA EN UNA DIRECCION PREFERENTE DURANTE EL PROCESAMIENTO, FORMANDOSE DESPUES EN UNA GEOMETRIA FINAL ANTES DEL CURADO MEDIANTE RADIACION DE HACES ELECTRONICOS DE ALTO VOLTAJE, PREFERENTEMENTE EN EXCESO DE 3.000.000 DE ELECTRONVOLTIOS. EL CURADO DE HACES ELECTRONICOS EN ESTADO SOLIDO FIJA PROPIEDADES MAGNETICAS, ESTABILIDAD DIMENSIONAL, RESISTENCIAS PARCIALES AL ACEITE, DISOLVENTES Y PRODUCTOS QUIMICOS, INCLUSO CUANDO SE EXPONEN A AMBIENTES POSTERIORES DE TEMPERATURAS HOSTILES DE 125 C O SUPERIORES. CUALQUIERA, SALVO LAS PARTES GEOMETRICAS O DISPOSICION PRODUCIDAS EN EL PROCEDIMIENTO CON ANTERIORIDAD AL CURADO POR RADIACION, PUEDE RECICLARSE PROCESANDO VARIAS VECES SIN TEMOR A CURA PREMATURA.
