2. Overall Structure and General Principles
The ZJL series torque rheometer consists of three core components: measurement and control host, mixer, and single/twin-screw extruder. Adopting a flexible modular design, the measurement and control host can work independently with the mixer or extruder, realizing multiple rheological performance tests with one machine and featuring high practicability and adaptability.
2.1 Measurement & Control Host + Mixer (Formula R&D Testing)
This combination is mainly used for formula debugging and performance analysis of polymer materials, especially for the auxiliary agent ratio research of PVC and other modified materials. It can accurately detect key rheological parameters of materials with different proportions of additives, including maximum/minimum torque value, filler peak, melting point, thermal stability time and cross-linking time. Based on the changing rules of data, researchers can directly judge the rationality of additive ratios, quickly optimize product formulas and greatly improve the efficiency of new material R&D.
2.2 Measurement & Control Host + Extruder (Production Process Simulation)
This combination focuses on the process simulation of thermoplastic materials, which can restore the actual production conditions such as temperature, screw speed and shear rate. By adjusting different processing temperatures and screw speeds, it detects the changes of shear stress and shear viscosity of materials under different shear rates, generates accurate rheological curves and truly simulates industrial production scenarios. Relying on measured data, it can accurately optimize production process parameters, avoid processing defects and provide scientific and reliable technical guidance for large-scale production.
