Mixed Shear Torque Rheometer
The intensive mixer unit of the torque rheometer mainly consists of imported servo motors, high-precision dynamic torque sensors, gearboxes, kneading chambers, temperature modules, measurement modules, computers, and control software. The enclosed mixer is akin to a miniature kneading machine, composed of a removable "∞" shaped mixing chamber and a pair of rotors rotating in opposite directions at different speeds. Within the mixing chamber, the rotors rotate in opposite directions, applying shearing force to the material, forcing it to be mixed within the chamber; the different speeds of the two rotors result in dispersive mixing in the gap between them.

The enclosed mixer is akin to a miniature rubber mill, consisting of a removable "∞"-shaped mixing chamber and a pair of rotors that rotate in opposite directions at different speeds. Inside the mixing chamber, the rotors rotate in opposite directions, applying shearing to the materials, forcing them to be mixed within the chamber; due to the differing speeds of the rotors, a dispersing mixing occurs in the gaps between them.

The unit boasts an overall aesthetic appearance, with the main sheet metal featuring a white and blue color scheme, which can also be customized according to customer requirements. The stainless steel parts are made of SUS304 stainless steel.

Computer software is capable of data collection, storage, calculation, analysis, and output, and can print test reports according to user requirements.
