Moving Die Rotor Rheometer Working Principle
The rubber sample is placed in a nearly completely closed cavity and maintained at the test temperature. The cavity has two upper and lower parts, wherein the lower part reciprocates with a slight linear motion (oscillation), and the sample is sheared by oscillation. The reaction torque (force) of the sample to the cavity is determined, and the magnitude of the torque (force) depends on the shear modulus of the rubber.
After the start of the vulcanization test, the shear modulus of the sample increases, and the computer displays and records the torque (force) in real time. When the torque (force) rises to a stable value or a maximum value or even returns to the state, a torque is obtained. The relationship between force and time, that is, the vulcanization curve (Fig. 1), the shape of the curve is related to the temperature of the test and the characteristics of the compound.
