The capillary rheometer consists of precision screw extrusion system, capillary die or narrow slit die, and weighing unit. There are optional dies with different caliber and aspect ratio, extrusion by screw allows the polymer to pass through the capillary at a constant flow rate, by testing the pressure drop created between the two specific pressure points, under these conditions, the shear stress and shear rate of the polymer melt with Newtonian rheological properties were calculated through the software.
The filtration pressure value tester consists of precision screw extrusion system and special melt pump. The melt pressure sensor is installed in front of the pump and a pressure-screw-speed control loop is formed. Screen changer can be disassembled and assembled easily and quickly for easy replacement of the screen, the perforated plate support multi-layer screen. The test curves and reports of FPV filtration pressure value can be generated by testing and recording the pressure changes during polymer extrusion with melt pressure sensor through dedicated software.
Main Test & Control Module is a control console with the function of driving and controlling measurement units. This modular structure has good expandability and adaptability, and can be equipped with various functional modules. Controlled auxiliary machines such as torque and extrusion units are intelligent, application-specific measurement units that transmit measurement data to the host.
The torque module is connected with Main Test & Control Module to constitute a torque rheometer, which is used to analyze the plasticization and rheological properties of polymer materials, helping users to carry out inspection and processing design of raw materials.
This capillary extrusion module is connected with Main Test & Control Module, together with the capillary die and the weighing unit to constitute a capillary rheometer. By testing the pressure drop created between the two specific pressure points, under these conditions, the shear stress and shear rate of the polymer melt with Newtonian rheological properties were calculated through the software.
