Working principle of Mooney viscosity testing machine
The Mooney viscosity tester works by measuring viscosity based on the torque generated by a rotor as it rotates in a rubber sample. The specific steps are as follows:
1.Sample preparation: Put the rubber sample to be tested into the mold cavity of the testing machine and preheat it to the set temperature.
2.Rotor rotation: Start the testing machine, the rotor rotates at a constant speed, and the rubber sample generates torque on the rotor due to viscous resistance.
3.Torque measurement: The sensor measures the torque in real time and converts it into Mooney viscosity value.
4.Data processing: The testing machine automatically records and analyzes data and generates a Mooney viscosity curve.
