Mooney Viscometer DMV2025 manufacturer takes you to understand briefly what is Mooney Viscometer
The Mooney Viscometer DMV2025 manufacturer tells you that the Mooney Viscometer is an instrument used to measure 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 high-precision sensors, control systems, rotating systems, temperature control systems, data transmission methods, display methods, rotors, measurement and control methods are the main technical indicators of Mooney viscometers.
The Mooney Viscometer DMV2025 manufacturer tells you that the Mooney Viscometer consists of a rotating spindle and a heated mold. The substance surrounds the spindle and overflows from the spindle, and the Mooney viscosity is calculated based on the torque on the spindle. The Mooney Viscometer DMV2025 manufacturer tells you that the working principle of the Mooney Viscometer is to measure the torque required to rotate a disc in a cylindrical chamber containing the rubber compound to be vulcanized. The number proportional to the torque value is used as the viscosity index (Mooney viscosity), expressed in arbitrary Mooney units. The rubber mixture is introduced under pressure into a test chamber composed of two halves. The manufacturer of Mooney Viscometer DMV2025 tells you that inside the test room, the disc is rotated by a motor. In order to avoid rubber slipping during the determination process, the chamber wall and rotor surface must be treated with horizontal graining. The Mooney Viscometer DMV2025 manufacturer tells you that the conversion of torque into viscosity units is performed by a calibrated leaf spring anchored on the shaft of the turntable. The deformation of the shaft is transferred to the indicating scale. Choose the elasticity of the spring so that a torque of 84 daN.cm corresponds to 100 viscosity units. The chamber is electrically heated, and the temperature is kept constant within 0.5 degrees Celsius.
