Abstract

LA EFICACIA DE LA CARGA ELECTROSTATICA DE UNA BOBINA DE POLIOLEFINO EN UN PROCESO PARA ENROLLAR EL PLEXIFILAMENTO DE POLIOLEFINO DE LA SOLUCION EN UN HIDROCARBURO C{SUB.4}-C{SUB.7}, FORMANDO EL PLEXIFILAMENTE EN UNA BOBINA, CARGANDO ELECTROSTATICAMENTE LA MISMA, Y DEJANDO CAER LA BOBINA COMO UNA LAMINA, SE MEJORA AL TENER PRESENTE EN EL PASO DE CARGA ELECTROSTATICA UN COMPUESTO DE MEJORA DE CARGA, QUE PUEDE SER CUALQUIERA DE UN NUMERO DE CLASES ESPECIFICAMENTE IDENTIFICADAS DE COMPUESTOS DE MEJORA DE CARGA. LOS COMPUESTOS DE MEJORA DE CARGA SE ENCUENTRAN PRESENTES EN UNA CANTIDAD DE AL MENOS 0,1 PPM, O MAS, DE LA ATMOSFERA EN ESE AMBIENTE.
