Abstract

UN TONER MAGNETICO ESTA FORMADO POR UNA RESINA AGLUTINANTE Y PARTICULAS MAGNETICAS DE OXIDO DE HIERRO QUE CONTIENEN SILICIO. EL TONER MAGNETICO TIENE UN TAMAÑO DE LAS PARTICULAS CON PESO MEDIO DE COMO MAXIMO 13,5 (MU)M Y EL TONER TIENE UNA DISTRIBUCION DEL TAMAÑO DE LAS PARTICULAS TAL, QUE LAS PARTICULAS DEL MISMO QUE TIENEN UN TAMAÑO DE POR LO MENOS 12,7 (MU)M ESTAN CONTENIDAS EN UNA CANTIDAD DE A LO SUMO EL 50 % EN PESO. LAS PARTICULAS MAGNETICAS DE OXIDO DE HIERRO TIENEN UN CONTENIDO DE SILICIO DESDE 0,4 HASTA 2,0 % EN PESO BASADO EN HIERRO Y LAS PARTICULAS MAGNETICAS DE OXIDO DE HIERRO TIENEN UNA RELACION ATOMICA FE/SI DE 1,2 CAUSA DEL USO DE TALES PARTICULAS MAGNETICAS DE OXIDO DE HIERRO QUE TIENEN UN CONTENIDO DE SI GLOBAL Y SUPERFICIAL ESPECIFICAMENTE CONTROLADO, EL TONER MAGNETICO PUEDE PRODUCIR RENDIMIENTOS ESTABLES INCLUSO DESPUES DE PERMANECER EN UN AMBIENTE CON ELEVADA HUMEDAD.
