| 摘要 |
The present invention refers to an on-line rotational/oscillatory rheometrical device inserted in the barrel of an extruder ( 1 ), composed of the main body ( 2 ), a cleaning ring ( 5 ) and a lower support ( 6 ), kept at a constant temperature, and a set of plates, upper ( 3 ) and lower ( 4 ) with an adjustable separation, with the upper one being animated with a rotating or oscillating movement, via a coupling to a rotation/measuring head of a commercial controlled-stress rheometer. The rotation of the ensemble allows a sample of material to be collected from the interior of the extruder and its subsequent Theological characterisation in the device.
