Moving Die Rheometer (MDR)

The Moving Die Rheometer has a minimum torque reading of 0.001Nm, which is highly helpful for providing precise measurements of the torque applied to the rubber sample during testing. This high level of sensitivity allows the rheometer to detect even the smallest changes in the material's stiffness, especially during the early stages of vulcanization when the rubber is soft and less resistant to deformation.

Accurate minimum torque readings are crucial for understanding the initial viscosity of unvulcanized rubber and for tracking how it cures under heat and pressure. This precision ensures that manufacturers and researchers can closely monitor the curing process, making it easier to optimize rubber formulations and ensure consistent product quality. The 0.001Nm sensitivity enables the rheometer to capture detailed data on a wide range of rubber compounds.

The Moving Die Rheometer offers swing angles of ±0.5°C, ±1°C, and ±2°C, with the standard matching angle being 1 degree. These swing angles refer to the range within which the oscillating die moves during testing, applying varying levels of shear strain to the rubber sample. The ability to choose between different swing angles allows for greater flexibility in testing, as it enables the rheometer to simulate different real-world strain conditions that rubber compounds may encounter.

This flexibility is important for accurately evaluating the material's behavior under different strain levels so that the curing process is assessed comprehensively. By offering multiple swing angles, the Moving Die Rheometer provides detailed insights into how different rubber formulations respond to mechanical stress. This allows for better optimization of the material’s properties for specific applications.

The Moving Die Rheometer operates with a swing angle of 100 revolutions per minute (r/min), or 1.66Hz. This swing angle refers to the frequency at which the die oscillates during the testing process, applying shear strain to the rubber sample. The oscillation is crucial for measuring the torque response of rubber as it undergoes vulcanization, which helps determine the material's stiffness (shear modulus) and curing characteristics.

The frequency of 100 r/min (1.66Hz) guarantees that the strain is applied consistently and accurately throughout the test, allowing for precise measurements of the rubber's behavior during the vulcanization process. This consistent swing angle is essential for ensuring repeatable and reliable data, which is critical for quality control and material development in the rubber industry. The specific swing angle settings allow for flexibility in adapting the test conditions to match different rubber formulations.

The Moving Die Rheometer requires an air pressure of 65 psi (4.6 bar) to operate effectively, though it does not include an air compressor. This air pressure is necessary to maintain the sealed test environment within the rheometer during testing so that the rubber sample is subjected to the correct pressure conditions throughout the vulcanization process.

Proper air pressure is crucial for obtaining accurate and consistent test results, as deviations in pressure could affect the mechanical properties of the rubber being tested. Maintaining stable air pressure allows the instrument to simulate real-world conditions more effectively, providing reliable data for quality control, research, and product development in the rubber industry. Users will need an external air compressor to supply the required pressure.

The Moving Die Rheometer is designed to accept rubber specimens with dimensions of 5 cm. This standard specimen size guarantees that the sample fits securely within the sealed test cavity, allowing the machine to perform accurate and consistent testing. Proper specimen dimensions are essential for maintaining uniform pressure and temperature during the test, which directly impacts the quality of the torque and curing data collected.

Using the correct specimen size is important for achieving reliable results, as it guarantees that the rubber material is subjected to the same conditions throughout the testing process. Consistent specimen dimensions help eliminate variability in testing, making the results more reproducible and comparable between different tests or production batches. This is critical for both research and quality control applications in the rubber industry.
