Abstract

Dispositivo para el desgasificado de materiales sintéticos, en especial de soluciones de policarbonato de peso molecular elevado, con una extrusora de doble árbol, que presenta árboles que giran en el mismo sentido, engranados entre sí, caracterizado porque la extrusora presenta una proporción longitud/diámetro menor/igual a 40, estando realizados los árboles en dos pasos en la zona de desgasificado de la extrusora, y en tres pasos en su zona de establecimiento de presión.
