1Overview

1.1Product Features

cableIn the process of processing and shaping, almost all materials involve their fluidity. For example, in processes such as extrusion, injection molding, blown film, and rolling, the flow behavior of materials is crucial. The fluidity of materials not only affects processing behavior, but also affects the mechanical properties of the final product. For example, molecular orientation has a significant impact on the mechanical properties of molded products, films, and fibers. The type and degree of molecular orientation are mainly determined by the characteristics of the flow field and the flow behavior of the material during the processing.

1System composition

The computer-controlled torque rheometer consists of a mixing torque rheometer, an extrusion capillary rheometer, a capillary testing die, a data acquisition and measurement system, an electronic computer, and operating software.

Internal torque rheometer:

The internal torque rheometer is mainly composed of imported servo motors, high-precision dynamic torque sensors, gearboxes, internal mixing chambers, temperature modules, measurement modules, computers, measurement and control software, etc. Its principle is shown in the figure2As shown:

image1 Internal torque rheometer

A closed mixer is equivalent to a small internal mixer, consisting of a The detachable mixing chamber in the shape of an "∞" and a pair of rotors rotating in opposite directions at different speeds. In the mixing chamber, the rotors rotate in opposite directions, applying shear to the materials and forcing them to mix in the mixing chamber; The two rotors have different speeds, resulting in dispersed mixing in their gaps.

The overall appearance of this machine is beautiful, and the main sheet metal adopts a color scheme of milky white and blue, which can also be processed according to the user's color requirements. The stainless steel part adoptsSUS304stainless steel.

Computer software has functions for data collection, storage, calculation, analysis, and output, and can print test reports according to user requirements.

system software

Supported software set byMixer - mixer test measurement and control software, Plastic - extruder test measurement and control software, WinNian - apparent viscosity test data processing software. The interface between Mixer and Plastic software is rich in functions, allowing for measurement, setting, and control of speed, torque, temperature, and pressure. The curve window can display real-time curves of the above data against time. These data can be processed and plotted by software. Under the experimental measurement and control software, an experimental report is generated and output by a color printer. It can also complete functions such as overlaying multiple curves and smoothing curves.
