1.working principles is different
Capillary rheometer is a device for measuring shear stress rate under high stress. It is used to measure the relationship between shear stress and shear rate of polymer melt in capillary tube, directly observe the shape of extruder, study the elasticity and instability of melt by changing the aspect ratio, and measure the state change of polymer, etc.
Torque rheometer is measured material will join in the mixing chamber, different material by speed, steering instead of the force imposed by the two rotor and was continuously mixing between the rotor and room wall shear, rotor rib has also been material reaction, torque rheometer in the reaction torque sensor measured, through the computer software, it is concluded that the torque rheological map changes over time.
2.The test data and function are different
Capillary rheometer is used to measure the relationship between shear stress and shear rate of polymer melt in capillary tube, directly observe the shape of extruder, study the elasticity and instability of melt by changing the aspect ratio, and measure the change of polymer state. It can perform apparent/true viscosity curve test and extrusion swelling behavior measurement and analysis
Torque rheometer is through the records of material in the process of mixing on the rotor torque and temperature change with time, the continuous, accurate and reliable determination of the rheological properties of materials, such as the mixture of multicomponent materials, crosslinking curing thermosetting resins, elastomer curing, the dynamic stability of the material and the screw rotation speed affect the performance of system processing, etc
3.Different structure
The single screw extruded capillary rheometer is designed with modular structure, which can be achieved by different combinations function. This set of small equipment is composed of a single screw extrusion unit, a capillary mold and an online automatic weighing unit.
The single screw extrusion unit is controlled by the frame, motor, transmission assembly, extrusion assembly, operation screen and electrical control system etc composition
The torque rheometer system usually consists of a main drive unit, an additional component
Analysis sensor, computer system, mixer, single screw extruder,twin screw extruder, a variety of die and other auxiliary equipment.
