According to reports, scientists have discovered a strange "synthetic liquid" by using an extensional rheometer.
According to reports, in this research, scientists have adopted a brand-new method to discover and understand the fluidity of this concentrated liquid. Previously, they used a dynamic shear rheometer, but this detection method did not fully reflect the application of the liquid in the actual industrial production process. So, the scientists turned to another tool-the extensional rheometer. The research results were subsequently published in British journals.
Determination
There are several types of instruments for measuring the shear viscosity and fluidity of polymers: falling ball type, rotating type (including various modified Mooney viscometers), oscillating type (torsional vibration rheometer and disc oscillation rheometer) , Mixing model [plastic meter] and capillary extrusion type (capillary rheometer and processing performance tester), etc. The above-mentioned various test instruments and measuring methods have their own advantages, disadvantages and scope of application, which can complement each other.
