The torque rheometer is developed by our company. All the processes are controlled by computer. Large-scale integrated blocks are used. The data acquisition, control and processing of experimental data are all completed by the corresponding software. This is not only the operation of the instrument, the control is accurate, the experiment Data processing and result output are fast and efficient, and more importantly, with the support of software, the functions that the traditional torque rheometer can't do, such as the shear sensitivity of the linear speed measurement material, the viscosity spectrum measurement process Pressure inlet calibration and non-Newtonian fluid correction.
Moment rheometer is an ideal equipment for studying the flow, plasticization, heat and shear stability of materials. The rheometer provides a dynamic measurement method closer to the actual processing, which can be continuous under similar actual processing conditions. Accurate and reliable measurement of the rheological properties of materials, such as the mixing of multi-component materials, cross-linking curing of thermosetting resins, vulcanization of elastomers, dynamic stability of materials and the effect of screw speed on the processing properties of the system.
It can be used to study the thermal stability, shear stability, flow and plasticizing behavior of thermoplastic materials. Its great feature is that it can continuously and accurately measure the rheological properties of the system in a similar actual processing process, and can also be completed. Curing characteristics test of thermosetting materials. It is of great value to the development of teaching, scientific research and new materials and the determination of production process strips.
In recent years, computer measurement and control technology has made great progress. We have incorporated more new technologies into the plasticizer testing technology, especially the revolutionary changes brought by the Windows operating system to PC information processing capabilities, data acquisition and control. And the processing of experimental data is completed by the corresponding software, which can form many characteristics such as strong flexibility, strong information management and processing ability, and is extremely convenient to use and can obtain more physical property information of synthetic materials. This not only shows that the instrument is easy to operate, the control is precise, the experimental data processing and the result output are fast and efficient, and the die can be corrected during the measurement process of the apparent viscosity and shear rate of the material.
The basic principle of torque rheometer
Main composition
The equipment mainly consists of: (1) main drive system (2) mixing unit (3) plastic extrusion unit (4) main measurement and control system (5) multi-stage temperature measurement and control system (6) measurement and control system (7) data acquisition system (8) Computer experiment software and data processing system
2. Working principle
The machine is equipped with a screw with different parameters, which rotates in a cylinder with a certain temperature, and the other end of the cylinder is provided with a feeding hopper. When the raw material is sent to 2/3 of the cylinder, it is gradually plasticized, and it is homogenized into the remaining part of the cylinder. When all the particles are melted, the capillary extrusion die can be used as a masterbatch or an injection mold to form, and the device is formed. Measurements of the relationship between the apparent viscosity of the material and the shear rate and shear stress are also completed.
The device support software set consists of the apparent viscosity test software plastic and the apparent viscosity test data processing software WinNian. The plastic software can realize the collection and parameter control of the test data through the serial port of the PC, and establish the human-machine information interaction interface, as shown in Figure 1. This interface is relatively complete, can complete 6-channel temperature measurement and control, including speed setting, measurement and control, torque, pressure measurement and so on. The curve window can display the above data versus time curve in real time. These data can be processed by dedicated WinNian data.
When the screw speed of the extruder is changed, the P value of the pressure difference inside and outside the die and the Q value of the extrusion flow rate can be changed, and the test data can be saved in the form of a file. The file is opened in the software WinNian, and the gh, gt curve which automatically outputs the double logarithmic coordinates with representative data is filtered out.
