Abstract

TRANSPORTADOR MAGNETICO PARA SER UTILIZADO EN EL REVELADO ELECTROFOTOGRAFICO QUE TOMA LA FORMA DE PARTICULAS DE NUCLEO DE FERRITA, CADA UNA DE ELLAS CON UNA CAPA PROTECTORA RESINOSA. LAS PARTICULAS CON NUCLEO DE FERRITA TIENEN UNA DISTRIBUCION DE TAMAÑO DE PARTICULAS LIMITADA Y ESTAN CUBIERTAS POR UNA COMPOSICION RESINOSA BASADA EN UN COPOLIMERO QUE ESTA FORMADO ESENCIALMENTE DE METACRILATO DE ETILO, 15 A 25% POR PESO DE ESTIRENO, HASTA UN 2% POR PESO DE METACRILATO DE DODECILO, Y HASTA UN 2% POR PESO DE ACRILTO DE 2-HIDROXIETILO. LAS PARTICULAS TRANSPORTADORAS MAGNETICAS TIENEN UNA RESISTENCIA DE 8.5X10 ELEVADO 7 A 2.2X10 ELEVADO 9 (OMEGA). ESTE TRANSPORTADOR TIENE UNA DISTRIBUCION REPENTINA DE CARGA ELECTRICA Y UNA ELEVACION RAPIDA DE FUNCIONAMIENTO CAMBIANTE. LA CAPA PROTECTORA ES LO SUFICIENTEMENTE ESPESA COMO PARA IMPARTIR DURABILIDAD AL TRANSPORTADOR.
