Abstract

EN UN PROCEDIMIENTO PARA LA ELABORACION DE POLIMEROS GRANULADOS O POLVOSOS CON ADITIVOS EN POLVO EN UNA MAQUINA PARA FUNDICION INYECTADA, QUE DISPONE DE UN SINFIN CON UNA ZONA DE ENTRADA CON UN DIAMETRO CONSTANTE DEL SINFIN, UNA ZONA INTERMEDIA CON UN TRAMO DE HERMETIZACION Y UNA FORMACION DE ELEMENTOS DE MEZCLADO. SE HA PREVISTO UNA ELABORACION ESPECIALMENTE ECONOMICA CON PIEZAS DE FUNDICION DE GRAN CALIDAD, PARA QUE EL POLIMERO Y LOS ADITIVOS EN POLVO PUEDAN INTRODUCIRSE A LA ZONA DE ENTRADA SIN PREVIO TRATAMIENTO Y PARA QUE EL POLIMERO CON LOS ADITIVOS PUEDA MEZCLARSE POR LO MENOS DOS VECES MEDIANTE LAS FORMACIONES DE ELEMENTOS DE MEZCLADO, SIENDO LA LONGITUD DE TRABAJO DEL SINFIN POR LO MENOS 19 VECES MAS GRANDE QUE EL DIAMETRO DEL SINFIN.
