Abstract
EL INVENTO SE REFIERE A UN PROCESO PARA LA MEZCLA DE UN COMPUESTO POLIMERO USANDO UN MEZCLADOR INTERNO QUE TIENE DOS ROTORES (18,20) MONTADOS EN UNA CAMARA (12), UN PISTON (28), MEDIANTE EL CUAL SE PUEDE APLICAR PRESION AL MATERIAL EN LA CAMARA (12) Y UN CONTROL DE TEMPERATURA PARA EL MEZCLADOR. LOS MATERIALES SE INTRODUCEN EN LA CAMARA (12) Y, AL MENOS, TRES VARIABLES DE MEZCLADO, TALES COMO TEMPERATURA, TIEMPO Y ENERGIA, QUE INDICAN LA CALIDAD DEL MEZCLADO SE MONITORIZAN Y VARIABLES DE CONTROL, TALES COMO LA VELOCIDAD DEL ROTOR Y/O LA PRESION DEL PISTON AJUSTADAS DEPENDIENTEMENTE DE LAS VARIABLES DE MEZCLADO MONITORIZADAS PARA ALCANZAR LOS RESULTADOS DEFINIDOS PREVIAMENTE. EL CONTROL SE INICIA CUANDO EL PISTON HA ALCANZADO UNA POSICION PREDETERMINADA Y CUANDO POR LO MENOS UNA CONDICION PRESELECCIONADA, TAL COMO EL TIEMPO, LA TEMPERATURA O LA ENERGIA, SE HA ALCANZADO. EL MEZCLADOR INCLUYE UN COMPUTADOR (44) QUE EFECTUA EL CONTROL Y DISPONE LAS RELACIONES DERIVADAS ENTRE LAS VARIABLES DECONTROL Y DE MEZCLA MEDIANTE LAS CUALES SE CONTROLA EL PROCESO.
