Abstract

UN DESARROLLADOR MAGNETICO PARA DESARROLLAR IMAGENES ELECTROSTATICAS SE CONSTITUYE POR PARTICULAS DE COLORANTE MAGNETICO, CONTENIENDO CADA UNA UNA RESINA ADHESIVA QUE TIENE UNA VISCOSIDAD FUNDIDA DE COMO MAXIMO 5,0X(10)6 POISES A 150 ATERIAL MAGNETICO. EL MATERIAL MAGNETICO ESTA MEZCLADO CON UNA PROPORCION (C) [% DE PESO] DE FINAS PARTICULAS INORGANICAS BASADAS SOBRE EL MATERIAL MAGNETICO PARA TRANSPORTAR 0,2 PESO DE LAS FINAS PARTICULAS INORGANICAS ASEGURADAS A LA SUPERFICIE DEL MATERIAL MAGNETICO. EL MATERIAL MAGNETICO TIENE UN AREA (A) DE SUPERFICIE [M (AL CUADRADO) /G] ANTES DE ASEGURARSE A LAS FINAS PARTICULAS INORGANICAS Y SE PROPORCIONA CON UN INCREMENTO EN AREA (B) DE SUPERFICIE POR ASEGURARSE A LAS FINAS PARTICULAS INORGANICAS; EN DONDE LOS PARAMETROS A, B Y C SATISFACEN LA SIGUIENTE FORMULA (1) Y (2): 0,1 (MENOR O IGUAL) B/A (MENOR O IGUAL) 0,8 (1) B< 30 X C (2). COMO UN RESULTADO, EL DESARROLLADOR MAGNETICO ESTA PROVISTO CON UNA FIJABILIDAD MEJORADA A BAJA TEMPERATURA SIN OCASIONAR PROBLEMAS QUE ACOMPAÑAN EL USO DE UNA RESINA ADHESIVA QUE SE ABLANDA A BAJA TEMPERATURA, TALES COMO DETERIORO DE CARACTERISTICAS ANTI-MACULADO, CARACTERISTICAS DE ALMACENAMIENTO, CARACTERISTICAS DE DESARROLLO.
