The Mooney Vicometer manufacturer tells you that Mooney viscosity reflects the quality of rubber processing performance and molecular weight and wide distribution range.

The Mooney Vicometer manufacturer tells you that Mooney viscosity reflects the quality of rubber processing performance and molecular weight and wide distribution range. With high viscosity, the rubber is not easy to mix uniformly and extrusion processing, its molecular weight is high, the distribution range is wide, and the relative hardness is relatively high. Higher strength and relatively more powder can be filled. The low viscosity of rubber and easy sticking rollers have a narrow low molecular weight distribution range. If the Mooney viscosity is too low, the tensile strength of the cured product will be low.

The Mooney Vicometer has different effects
1. In the case of the same formula, when the Mooney value is high, the physical properties are better, and when the Mooney value is low, the physical properties are poor.
2. When the ingredients are well dispersed, the Mooney value will decrease. If the dispersion is not good, the abrasion resistance is poor; the Mooney value is high, which has a reinforcing effect on tension and tearing.
3. The Mooney value is used to control processability. Good processability, can ensure that the rubber material flows into every corner of the injection mold, and the vulcanization of various colored rubber materials is easier to control, which can reduce waste.
4. The Mooney Vicometer manufacturer tells you that when the Mooney value is low and the elongation is high, the wear resistance is better.
5. The opposite is true when the Mooney value is low. For example, in the shoe sole formula, the formula with low Ni value tends to "run off" easily.
The Mooney Vicometer manufacturer tells you that the excellent function of the humanized design is that you can modify the measurement time during the test. If it is more than ten minutes, it will be measured 1 to 2 minutes earlier. If it is a small rotor, the measurement has been completed. If it is a large rotor, the measurement is also completed. At this time, there is no need to do it again. Press "Send as" and the experiment will stop immediately. When the data is displayed in advance, draw the complete Mooney curve, calculate all the data, and add The data curve is stored in the database. The Mooney Vicometer manufacturer tells you that if the test is not measured for a long time for several tens of minutes, the experiment will automatically move down several points and several points, and it is also possible to manually modify the measurement time until it is measured. If it is not measured for several hundred minutes, this measurement will be automatically ended. This feature undoubtedly greatly facilitates the user and saves valuable time and rubber.
Mooney Vicometer is used to determine the viscosity and vulcanization index of rubber compounds. When the sample is at a certain temperature and pressure, the rotor applies a certain shearing force to the sample with a certain rotating torque, and the instrument measures the anti-shearing torque of the rubber. It is an indispensable instrument in the reclaimed rubber, rubber, wire and cable industries.
