Capillary Rheometer Test Operation

Extrusion capillary rheometer is a device used to measure shear stress rate under high stress. It can measure the fluidity and curing speed of thermosetting materials, draw stress-strain curves and plasticization curves of thermoplastic materials, and measure the temperature of softening point, melting point, and flow point. It can measure the viscosity and viscosity-flow activation of polymer melts, and study the process conditions of melt spinning.
It is used to measure the relationship between shear stress and shear rate of polymer melts in capillaries, directly observe the appearance of extrudates, study the elasticity and instability of melts by changing the aspect ratio, and measure the state changes of polymers. The study of polymer rheological properties can not only provide the best process conditions for processing and provide data for plastic machinery design parameters, but also obtain useful data on structural and molecular parameters in terms of material selection and raw material modification. There are more simulation processing modes and a wider shear rate range.
