Abstract

La presente descripción incluye un método para determinar una resistencia a la fusión que incluye extruir uno o varios polímeros para formar la película polimérica. pasar la película polimérica al menos parcialmente alrededor de un rodillo de medición acoplado con un dispositivo de medición de fuerza, al menos parcialmente alrededor de un rodillo de enfriamiento corriente abajo del rodillo de medición, y a través de un pellizco definido entre dos rodillos de presión. y medir una fuerza ejercida sobre el rodillo de medición por la película polimérica usando el dispositivo de medición de fuerza. La película polimérica está al menos parcialmente fundida cuando entra en contacto el rodillo de medición. Un sistema incluye un extrusor, un rodillo de medición acoplado con una o varias celdas de carga, un rodillo de enfriamiento acoplado con un motor de accionamiento, al menos dos rodillos de presión corriente abajo del rodillo de enfriamiento y un rodillo de recogida corriente abajo de los rodillos de presión. Las celdas de carga miden una fuerza ejercida por la película polimérica fundida sobre el rodillo de medición.
