Publish Time: 2025-02-07

In modern materials science and plastics processing industry, torque rheometer plays a vital role as an efficient and precise experimental equipment. It is not only an all-round analyst for studying plastic rheological properties, but also an important tool for promoting innovation and optimization of plastics processing technology.

Torque rheometer is an experimental instrument specially used to study material flow, plasticization, thermal stability and shear stability. Its core is to continuously, accurately and reliably measure the rheological properties of materials by simulating the actual processing process. This process involves the mixing of multi-component materials, the cross-linking and curing of thermosetting resins, the vulcanization of elastomers, and the dynamic stability of materials. The torque rheometer detects the processing rheological properties of polymer materials by measuring the torque and temperature change characteristics of the system under the kneading action of a pair of rotors rotating in opposite directions.

The working principle of torque rheometer is based on its precise measurement and control system and functional units. The measurement and control host provides a basic working environment, completes data acquisition and recording, and provides power and control for each functional unit. Functional units, such as twin-rotor mixers, single-screw extruders, and parallel twin-screw extruders, are connected to the measurement and control host in the form of building blocks to achieve specific experimental, measurement, and analysis functions. With the support of corresponding software, these functional units can flexibly respond to various complex experimental needs.

In the plastics industry, torque rheometer is particularly widely used. It can not only measure and simulate the processing rheological properties of plastics and optimize processing parameters, but also evaluate the processing performance of materials and predict possible problems in actual production. For example, in the processing of polyvinyl chloride (PVC), torque rheometer can measure the rheological curve of PVC dry blends to understand the influence of each component in the formula on the processing performance of the material. This is of great significance for optimizing the formulation design of PVC, improving processing efficiency, and reducing production costs.

In addition, torque rheometer also plays an irreplaceable role in the research and development of new plastic products. By simulating real processing technology and environment, torque rheometer can study the rheological behavior of polymer materials and provide strong experimental support for the final development of new products, guidance of production, and quality control. In the research of processing technology and formulation of materials such as thermoplastics, thermosetting plastics, rubber, and elastomers, the application of torque rheometer is indispensable.

It is worth mentioning that torque rheometer also has the characteristics of high automation and intelligence. Modern torque rheometer has integrated advanced computer measurement and control technology, and data acquisition, control, and experimental data processing are all completed by corresponding software. This not only makes the instrument operation more convenient and the control more precise, but also greatly improves the efficiency and accuracy of experimental data processing. At the same time, torque rheometer also supports remote operation and control, allowing experimenters to observe the entire detection process at different locations, further improving the flexibility and convenience of the experiment.

In summary, as an all-round analyst of plastic rheological properties, torque rheometer plays a vital role in materials science and plastic processing industry. It not only provides strong experimental support for the innovation and optimization of plastic processing technology, but also provides reliable guarantee for the research and development of new plastic products and the control of production quality.
