Mooney Viscometer DMV2025 manufacturer takes you to understand the working principle of Mooney Viscometer
The Mooney Viscometer DMV2025 manufacturer tells you that the Mooney Viscometer is an instrument used to determine the Mooney viscosity of raw rubber or rubber compound. It provides three measurement data, one is the measurement of Mooney viscosity, and the other is the measurement of stress relaxation characteristics. The third is the determination of scorch time.
The Mooney Viscometer DMV2025 manufacturer tells you that the Mooney Viscometer is a standard rotor. It adopts imported intelligent digital temperature control instrument, which is easy to adjust and set and has a wide temperature control range. The manufacturer of Mooney Viscometer DMV2025 tells you that the microcomputer adopts imported chips, which has high reliability, and all data can be automatically graphed, calculated and printed. At a constant speed (generally 2 rpm), rotate in the sample in the closed chamber. The shear resistance experienced by the rotor rotation is related to the viscosity change of the sample during the vulcanization process. It can be displayed on the dial with Mooney as the unit by the force measuring device, and the value can be read at the same time interval to make Mooney vulcanization. In the curve, when the Mooney number first drops and then rises, the time when it rises 5 units from the lowest point is called the Mooney scorch time, and the time when the Mooney scorch point rises by 30 units is called the Mooney vulcanization time.
The Mooney Viscometer DMV2025 manufacturer tells you that the Mooney Viscometer reflects the processing performance of rubber, the level of molecular weight and the wide range of distribution. The compound with high Mooney viscosity is not easy to be mixed uniformly and extruded. Its molecular weight is high and the distribution range is wide. The manufacturer of Mooney Viscometer DMV2025 tells you that the low Mooney viscosity rubber is easy to stick to the roller, and its molecular weight is low and the distribution range is narrow. If the Mooney viscosity is too low, the tensile strength of the cured product will be low. The time curve of the Mooney viscometer can also see the performance of the rubber vulcanization process.
