Embodiment Construction
[0017] In order to understand the technical solution of the present invention more clearly, the present invention will be further described below with reference to the accompanying drawings.
[0018] Such as Figure 1 to Figure 4 As shown in the figure, a single-cylinder capillary rheometer includes a cylinder 2. The front end of the cylinder 2 is provided with a plunger 1, the rear end is provided with a movable nut 6, and an electric heater 2 is arranged around the cylinder. The long capillary die 9, the supporting member 8 and the zero-length capillary die / short capillary die 7, the upper end of the plunger 1 is connected with a servo motor, and also includes a first pressure sensor 4 and a second pressure sensor 5. The first pressure sensor 4 is close to the upper end of the long capillary die, and the second pressure sensor is close to the supporting member 8. The long capillary die 9 and the zero-length capillary die / short capillary die 7 are in series, A supporting member...
