LRTOI-30/10 torque rheometer’s advanced technology and unique advantages are adopted and developed by Zero Degree, which is bound to make it one of the preferred equipment for polymer laboratory equipment. It is an ideal device for studying the flow and deformation, plasticization, thermal shear stability, dynamic rheological properties and plasticization behavior of polymer materials and expressing the results in the form of torque-time and torque-temperature charts, as well as the mixing of multi-component materials, cross-linking and curing of thermosetting resins, vulcanization of elastomers, dynamic stability of materials and the influence of screw speed on system processing performance. It can be widely used in scientific research and production. The laboratory simulates the mixing and extrusion process in production to obtain a series of data to guide the research and production of formulations in reality. It can continuously, accurately and reliably measure the rheological properties of materials under conditions similar to actual processing.
Product function:
LRTOI-30/10 torque rheometer has a modular design and ready-to-use function: the host is the control center, which has the function of driving and controlling the measuring unit; the controlled auxiliary machine (such as the mixing unit and the extrusion unit) is an intelligent measuring unit for specific applications, which can transmit the measurement data to the host through the bus system. It can be equipped with various auxiliary machines to complete laboratory simulation experiments for different purposes.

Structural principle and performance characteristics:
Structural principle:
Structural composition: A main measurement and control host is independently connected with the mixer or single-screw extruder or twin-screw extruder under different needs to form two modes of mixing rheometer and extrusion rheometer, which are identified by the program. LRTOI-30/10 torque rheometer, in addition to its main parts of the host, extruder, mixer, and computer, can also be equipped with automatic weighing unit, diameter measuring unit, three-roll calender, screw extruder, film blowing machine, strip sample calendering and traction unit, and film quality test unit as needed. These units can be used to complete more testing work:
- Automatic weighing unit: can automatically complete the measurement of the relationship between the apparent viscosity of the material and the shear rate and shear stress.
- Diameter measuring unit: complete the automatic measurement of die expansion.
- Strip sample calendering and pulling unit: can make uniform strip samples for tensile and thermal extension experiments.
- Film quality test unit: can complete the test of impurity particle defects and transparency of transparent materials.
The above optional units (conventional configuration does not include the above units) can be combined with other components with the measurement and control host and computer as the core to form different experimental systems. These functions are in a leading position in China.
