Lab Testing Equipment Torque Rheometer
It has played an important role in the research of plastic processing performance, rheological properties, mixing experiments and formulation design of raw materials and additives.
Description
Products Description
Add the material to be tested into the mixing chamber, and the material is subjected to the force exerted by the two rotors with different rotation speeds and opposite directions. The torque module measures this reaction force through the torque sensor, and the torque is obtained through computer software processing. Rheological profile over time. The equipment can simultaneously measure the torque (temperature)-time curve during the material mixing process, and detect the differences and characteristics of the microstructure, macroscopic shape, and processing performance of the material through the subtle changes in the curve.

Products case
- Problems with the modulus of elasticity of rubber materials: Rubber is a common torque-rheological material. The modulus of elasticity of rubber materials derived experimentally or computationally usually decreases as the torsional rate increases.
- Rheological properties of polymer solutions and slurries: Polymer solutions and slurries often exhibit torque rheology. For example, some polymer solutions change from a liquid form to a gel when subjected to shear, which is a manifestation of torque rheology.
- Applications in the food and pharmaceutical fields: torque rheology is widely used in the food and pharmaceutical fields. For example, in food processing, by studying the torque rheological properties of materials, the taste and texture of products can be improved. In pharmaceutical formulations, torque rheology studies can help optimize the stability, flow and release characteristics of drugs.
