Ⅵ 、Structure principle and performance characteristics

1）Structure and composition：A main measurement and control host is independently connected with the mixer or single-screw extruder or twin-screw extruder under different requirements to form two modes ； mixing rheometer and extrusion rheometer, which can be identified by the program.

ZJL series torque rheometer, in addition to the main part of the host, extruder, mixer, computer, can also be equipped with automatic weighing unit, measuring unit, three-roll calender, screw extruder, film blowing machine, strip sample calender and traction unit test unit.More testing can be done with these units.

2）System software

The supporting software set consists of Mixer -- mixer test and control software, Plastic -- extruder test and  control  software,  WinNian  --  apparent  viscosity  test  data  processing  software.  Mixer  and  Plastic software interface has rich functions, which can complete the measurement, setting and control of rotating speed, torque, temperature and pressure, and the curve window can display the curve of the above data versus the time in real time.These data can be processed and mapped by software, test and control software to form an test report, and output by color printer. It also has the functions of multiple curve superposition and smooth curve processing.

ZJL-200 torque rheometer is an automatic test instrument with computer as the core. Data acquisition, control and test data processing are completed by the relevant software.

This not only shows that the instrument is easy to operate, the control is accurate, the experimental data processing and the result output are fast and efficient 。More importantly, with the support of the software, it can  complete  the  functions  that  the  traditional  torque  rheometer  cannot  complete.For  example,  linear acceleration  measures  the  shear-sensitive  properties  of  a  material.Calibration  of      the  die  during  the measurement of the relationship between apparent viscosity and shear rate of materials.The design idea of ZJL-200 torque rheometer is to achieve function expansion and performance improvement through software development  on  the  basis  of  minimizing  the  increase  of  hardware  equipment,  so  it  has  a  high  cost performance.
