HST-CR5AComputer Controlled capillary rheometer

Ⅰ、Scope of application：

1、This machine is suitable for measuring the shear rate of plastics and polymer materials and the fluidity of the melt under shear stress at a certain temperature, including the apparent viscosity of thermoplastics and thermosetting materials.

2、 This rheometer is a computer-controlled intelligent Capillary rheometer, which can work under constant pressure, constant speed, constant temperature, different heating rates, different temperatures, different shear rates, etc. The software automatically determines the pressure, temperature, speed and other test parameters of different plastics under different die diameters. The software automatically draws curves and saves and prints data.

    3、Different specifications (low temperature type, high temperature type, different pressures, different rod diameters, etc.) can be customized according to user requirements. This machine has a low pressure, single pressure head, and single rod structure;

Ⅱ、The dynamic measurement and control capillary rheometer developed by our company has the following characteristics：

1、High data collection frequency (greater than 100PPS), can more accurately record the transition points of materials in different states without missing the key material state transition points; accurately calculate the apparent viscosity at different shear rates.

2、Can achieve the superposition of multiple data curve and display coordinates in various curve forms.

3、The load loading device of the instrument is designed reasonably, using high-precision pressure sensors for data acquisition, eliminating the traditional load sensor acquisition; Dual closed loop of software and hardware, achieving stepless adjustment of speed and loading force; Manual and automatic loading control can be used, which is convenient, fast, and accurate. Inductive manual displacement adjustment;

4、Regarding the coordinate axes of shear viscosity and shear rate curves: During the test, the coordinate axis is the normal coordinate axis. When the test is over, if you want to view the log coordinate axis image, you can directly adjust it with the mouse. So that you can observe the image in two ways, and the lowest point of the coordinate axis is set with the mouse after the test.

5、The whole machine adopts single rod、swing head table structure，which has more beautiful appearance, stronger stability, convenient cleaning, and easier transportation and installation.
