A brief introduction to Mooney Viscometer
Mooney Vicometer is a standard rotor, using imported intelligent digital temperature control instrument, easy to adjust and set, and wide temperature control range. The microcomputer adopts imported chips with high reliability, and all data can be automatically graphed, calculated and printed. Rotate in the sample in the closed chamber at a constant speed. The Mooney Vicometer manufacturer tells you that the shear resistance of 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. Mooney vulcanization curve can be made.
Mooney Vicometer principle When high frequency vibration is induced in a liquid, the vibration generated is inversely proportional to the mechanical resistance (ie viscosity) of the liquid. According to this principle, the instrument sends an ultrasonic signal of constant vibration speed through the ultrasonic generator in the sensor to act on the measured medium. The Mooney Vicometer manufacturer tells you to use the following equation to express the relationship between the parameters, and the microprocessor in the transmitter Refer to the stored data to calculate the viscosity or relative viscosity value at a certain temperature.
Mooney Vicometer reflects the quality of rubber processing performance, 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. Low Mooney viscosity rubber is easy to stick to the roller, its molecular weight is low, and its distribution range is narrow. If the Mooney viscosity is too low, the tensile strength of the cured product will be low. Mooney Vicometer time curve can also see the rubber vulcanization process performance.
