Laboratory torque rheometer |
LAB TORQUE RHEOMETER |
■ Explanation This machine is used to study the thermal stability, shear stability, flow and curing behavior of thermoplastic materials. It can continuously, accurately and reliably measure the rheological properties of materials under near real processing conditions. Typical experiments that can be completed include measuring the crosslinking characteristics of XLPE materials, measuring the fusion characteristics and thermal stability of PVC materials, and measuring the viscosity and shear rate of materials. |
oneScope of application
1. Quality control and raw material testing 2. Product development and formula optimization 3. Processing performance research and process optimization
4. Rheological properties testing of blends 5. Crosslinking (curing) properties testing of thermosetting materials 6. Teaching and research applications
II Composition and Function
1. Host: Receive and send data signals to control temperature and mechanical transmission, real-time measurement of pressure time, temperature time, torque time and other curve reportsTell me.
2. Mixing unit: divided into two types: 60ml and 300ml. The former mainly completes the rheological measurement and characterization of materials, while the latter completes the mixing and plasticization of materials,Can be used as a research formula for mixed materials. Equipped with rotors with three types of shear capabilities. Make the material between the rotor and the chamber walladvanceMixing and shearing forces with the same rotational speed but opposite directions.
3. Extrusion unit: Evaluate the processing performance of materials by simulating actual processing equipment. It can also be used in conjunction with capillary molds to measure the true viscosity of plastic melting at different shear rates, objectively characterizing the flowability of the material.
4. Other parts: optional traction, rolling, blown film, automatic measurement and weighing can be used to complete material modification, impurity measurement, tensile rheological research, etc., thereby achieving measurement throughout the entire production process from raw materials to finished product molding.
