Factors Affecting the Test Data of best Mooney Vicometer
Best Mooney Vicometer test data becomes less accurate due to various experimental factors, including:
1. Rubber mixing process and rubber parking time
The processes of plasticizing, mixing and thinning of rubber have a great influence on the test data of best Mooney Vicometer, that is, it is related to the preparation method of the sample. Therefore, when making comparison samples, the preparation of the samples should be carried out under the same method and process; the parking conditions and time of the rubber compound have a certain influence on the results of the viscosity test. , so as to avoid the tendency of the rubber to scorch during the parking process.
2. Preheating time
The preheating time directly affects the initial Mooney value of the rubber compound, which in turn affects the test data of best Mooney Vicometer. The preheating time should be strictly controlled.
3. The amount of glue
Since the volume of the cavity is fixed, the amount of glue loaded will affect the rotation of the rotor in the cavity. If the sample does not fill the cavity, the reproducibility of the test data will be affected, and the Mooney value measured by best Mooney Vicometer will be inaccurate.
4. Test temperature
The fluctuation of the test temperature will cause the fluctuation of the viscosity of the rubber compound, which will lead to the change of the torque value and the fluctuation of the Mooney curve, which will bring about the test error. Therefore, the test temperature range should be strictly controlled within the specified range to ensure the accuracy of the test data.
5. The degree of old and new rotors
After long-term use of the rotor, the surface pattern of the rotor will be worn and slipped, which will affect the test results of best Mooney Vicometer and should be replaced in time.
