Introduction: This machine is suitable for measuring the shear rate of plastics and polymer materials and the fluidity of the melt under shear stress under certain temperature conditions, including the apparent viscosity of thermoplastics and the apparent viscosity of thermosetting materials. This rheometer is an intelligent capillary rheometer for computer measurement and control. It can work under constant pressure, constant speed, constant temperature, different heating rates, different temperatures, and different shear rates. The software can automatically determine the Test parameters such as pressure, temperature and speed in different die environments. The software automatically draws curves, and saves and prints data. Features: 1. High frequency of data collection (more than 2. It can realize the superposition of various data curves; coordinate display in various curve forms. 2. It can realize the superposition of various data curves; the coordinate display of various curve forms. 3. The load-loading device of this instrument is designed reasonably, and the high-precision pressure sensor is used for data collection, eliminating the traditional load sensor collection; the software and hardware double closed loop realizes stepless adjustment of speed and loading force; manual and automatic two Kind of loading control, convenient, fast and accurate. 4. About the axis of shear viscosity and shear rate curve: The axis of the test is the normal axis. When the laboratory is over, if you want to watch the image of the log axis, you can directly adjust the log axis through the mouse, so that you can use it Observe the image in two ways, and the lowest point of the coordinate axis is set with the mouse after the test is over. 5. The whole machine adopts "H" frame structure, which has more beautiful appearance, stronger stability, and is easier to transport and install. 6. This machine adopts double barrels and some functions are mainly expanded on the basis of single barrel. Viscosity measurement is relatively more accurate than a single barrel, because a single barrel generally measures the apparent viscosity. The apparent viscosity measured with a single barrel is not the true viscosity of the material, but a double barrel can measure some parameters. With some corrections, the measured apparent viscosity is more accurate than the single cylinder measurement. 7. The software calculation of this machine adopts an open model design, the model can be corrected, different material systems, the results of other measurements are different, the two die of the double barrel can be corrected, (equipped with a long die and zero port Mold), simultaneously measure shear viscosity and extensional viscosity; carry out Bagley correction in real time. Of course, a single barrel is also possible, but there is no double barrel for more precision. 8. The machine adopts the structure of double indenters and double barrels. It can also make two samples at the same time or the same sample twice at the same time, which is conducive to the repeatability comparison of the same sample and the data comparison of different samples; Time; high work efficiency. 9. The graphic curve of the barrel displays pressure, temperature, force, shear rate, deformation and speed of the two pressure heads, and the remaining amount of sample in each barrel in real time technical parameter: Temperature range: room temperature~400℃ Heating rate: 1-10℃/min, continuously adjustable, and rapid heating Temperature measurement display accuracy: 0.1℃ Pressure range: 1-50MPa±0.5% Maximum driving force: 5、10、20KN Pressure measurement accuracy: ±0.5%FS Pressure resolution: 0.1Mpa Speed range: 0.01-500mm/min Deformation measurement accuracy: ±0.5%FS Plug diameter: φ12 mm Plug head area: 113.04mm2 Discharge die specifications: Ø 1×5, Ø 1×10, Ø1×20, Ø1×40 (mm×mm) (can be customized according to user requirements, price is negotiable) Discharge die material: tungsten carbide Power supply: 220V, 50Hz, power <1000W
