Abstract

EN UN DISPOSITIVO DE CARGA INCLUIDO EN UN APARATO FORMADOR DE IMAGEN PARA CARGAR UNA IMAGEN TRANSPORTADA UNIFORMEMENTE, UN RODILLO (2) CARGADOR TIENE UNA CAPA (5) ELASTICA Y UNA CAPA (6) SUPERFICIAL. LA CAPA (5) ELASTICA SE HACE DE UNA SUSTANCIA QUE TIENE UN MEDIO DE RESISTENCIA ELECTRICA Y QUE NO TIENE PARTICULAS CONDUCTORAS DISPERSADAS EN ELLA. LA CAPA (6) SUPERFICIAL SE HACE DE UNA SUSTANCIA NO ADHERENTE QUE TIENE UNA MAYOR PROPIEDAD DE NO ADHERENCIA QUE LA SUSTANCIA QUE CONSTITUYE LA CAPA (5) ELASTICA. LA CAPA (5) ELASTICA ESTA PRINCIPALMENTE CONSTITUIDA POR GOMA DE HEPICLOROHIDRINA Y LA CAPA SUPERFICIAL COMPRENDE UN FLUORADO QUE CONTIENE COPOLIMERO ENTRELAZADO.
