Abstract

SE PRESENTA UN APARATO Y UN PROCESO PARA DETERMINAR DE FORMA RAPIDA Y EXACTA LA REOLOGIA DE CORRIENTES DE POLIMERO FUNDIDO, DICHO APARATO COMPRENDE UNA EXCENTRICA (103) Y UNA PARED DE PRESION (101), UNA DE LAS CUALES ES UN MIEMBRO GIRATORIO Y LA OTRA ES UN MIEMBRO ESTACIONARIO, EL MIEMBRO GIRATORIO EMPUJA EL POLIMERO FUNDIDO AL INTERIOR DE UN HUECO EN FORMA DE CUÑA (107) ENTRE LA EXCENTRICA Y LA PARED DE PRESION, LA PRESION DEL POLIMERO DENTRO DEL HUECO SE MIDE MEDIANTE UN DISPOSITIVO DETECTOR DE LA PRESION (TR) CAPAZ DE PRODUCIR UNA SEÑAL EN RESPUESTA A DICHA PRESION EN FORMA DE INDICACION VISUAL, GRAFICO O VALOR NUMERICO ARBITRARIO, PERO PREFERIBLEMENTE DICHA SEÑAL SERA TRANSMITIDA A UN ORDENADOR PROGRAMADO PARA CALCULAR LA VISCOSIDAD APARENTE DE LA MATERIAL FUNDIDA DEL POLIMERO MEDIANTE LA APLICACION DE LA TEORIA "REYNOLD" DE LUBRICACION.
