Abstract

PROCEDIMIENTO PARA LA PREPARACION DE PARTICULAS PORTADORAS REVESTIDAS, UTILES EN MEZCLAS REVELADORAS ELECTROSTATOGRAFICAS PARA EL REVELADO DE IMAGENES ELECTROTASTICAS LATENTES. COMPRENDE LAS SIGUIENTES ETAPAS: PRIMERA, MEZCLAR EN SECO PARTICULAS DE NUCLEO PORTADORAS, SELECCIONADAS DEL GRUPO FORMADO POR HIERRO, ACERO, FERRITA, MAGNETITA, NIQUEL Y MEZCLAS DE LOS MISMOS, QUE TIENEN UN DIAMETRO PROMEDIO COMPRENDIDO ENTRE 30 Y 1.000 MICRAS, CON UN 0,05 A 3 POR 100 EN PESO, BASADO EN EL PESO DE LAS PARTICULAS PORTADORAS REVESTIDAS, DE PARTICULAS DE RESINA TERMOPLASTICA CUYAS DIMENSIONES ESTAN COMPRENDIDAS ENTRE 0,1 Y 30 MICRAS; SEGUNDA, AGITAR LA MEZCLA SECA FORMADA HASTA QUE LAS PARTICULAS DE RESINA TERMOPLASTICA SE ADHIERAN A LAS PARTICULAS DEL NUCLEO PORTADOR POR IMPACTACION MECANICA O ATRACCION ELECTROSTATICA; TERCERA, CALENTAR LA MEZCLA A UNA TEMPERATURA COMPRENDIDA ENTRE 160 Y 343G, DURANTE UN TIEMPO QUE VARIA ENTRE 120 Y 20 MINUTOS, DE TAL MANERA QUE LAS PARTICULAS DE RESINA TERMOPLASTICASE FUNDAN Y SE FUSIONEN A LAS PARTICULAS DEL NUCLEO PORTADOR; CUARTA, ENFRIAR LAS PARTICULAS PORTADORAS REVESTIDAS, Y, POR ULTIMO, CLASIFICARLAS AL TAMAÑO DE PARTICULA DESEADO. SE USAN MEZCLADAS CON PARTICULAS MATIZADORAS FINAMENTE DIVIDIDOS EN LA PREPARACION DE MEZCLAS REVELADORAS ELECTROSTATOGRAFICAS.
