1 Main Products introduction 1.1 The Principle of Mixer
The measuring principle is based on making visible the resistance the sample material opposes to
the rotating rotors. High-speed hot shearing provided by a pair of counter-rotating rotor in the mixer chamber made the material plasticizing from solid to melt.The corresponding torque moves a dynamo-meter out of its zero position .
In compliance with the existing standards and test specifications, a typical ' Rheogram ' (torque and temperature vs. time) is recorded for each sample material. We can analyse the structural changes of the material by the rheogram ,which shows the relationship between torque (viscosity) and temperature / time . The measured data can be displayed and stored numerically as a txt or excel file to further analysis during the measurement .
1.2 The Application of Torque Rheometer
With Hapro measuring mixers, you can simulate on a laboratory scale all processes like compounding, mixing, plasticity, heating and shear stability, extrusion ability etc. Hapro measuring mixers test the processing ability of thermoplastics, thermosets, elastomers, ceramic molding materials, pigments, and many other plastic and plastifiable substances.

2 System Components and SpecificationsRM-200C Torque Rheometer System consist of a main unit and function units,generally assembled by block models.The Main unit connects the other units to constitute the Mixer, Single Screw Extrusion unit, Conical Twin-screw Extrusion unit, Parallel Twin-screw Extrusion unit, Rubber Extrusion unit and downstream auxiliary equipment ,e.g. Laboratory Film Blowing Machine, Laboratory Film Casting Machine, Laboratory Film Calender Machine,Wire coating machine, Two-Roll Mills, Platen Presses, Film Quality Inspection System, Pelletizer, Sample cutter etc. System can not only simulate actual process of polymer, evaluate machining performance, optimize process parameters, but also completing simulation experiment to match different die heads .
2.1 Main Unit Main unit adopts the servo system imported from German, The heart of the Torque Rehometer is the fully digital 5.0 kW motor which ensures full torque of 190/240/320 NM over the entire speed range of 0.1 r/ min to 150/200/250 r/min. The inverter drive provides for precise and constant speed for functional units. Further more, a torque measurement is integrated. All important control data( e.g. temperature, pressure, speed, torque ) can be read on the computer . The output torque which reflects the viscosity changes to characterize the melt rheological properties.
The Main unit connected with a function unit can measure flow and compounding behaviors, critical processing parameters of temperature, pressure, torque and viscosity of polymers in the laboratory-requiring only small sample volume. The instrument, which is designed to a excellent system with high measuring precision, handling flexibility and testing reproducibility, has been widely used in science research, quality control and process experiment.

2.2 Single screw Extruder Platform:Laboratory Single screw Extruder can be integrated by main unit and single screw extrusion unit. That can be used to simulate real production process in the laboratory. Matched well with different die heads ,many functional simulation test in laboratory environment with Capillary Die,Pipe Die,Flat Die,Coating Wire Die and Other auxiliary equipments .The screw with different diameter, length-diameter radio and compress ratio can be chosen depending on the tested materials.
Equipment composition Single screw platform is consist of the Drive device, Feeding device, Barrel ,Screw and Dies parts, etc.The screw is the heart of the extruder, divided into the charging section (solid conveying zone), compression section(melting zone) and the homogenization section (the melt conveying zone) three parts.Put the material into the hopper ,under the action of a rotating screw,material was pushed on to direction of the nose.Material endures strong shear, mixing and calendering in the barrel,In this process, Meanwhile, the physical states of material the evolve from glass state to the high elastic state ,eventually become sticky flow pattern .
Principle Simulate Production Realistically on a Laboratory Scale ,single screw measuring extruder serves for testing the extrudability of polymers and for studying thesis occurring in research and development as well as in practical application. The single screw extruder system allows a complete instrumentation of the extruders for the control and development of raw material. Different screws, die heads, and downstream equipment fulfill all kinds of extrusion tasks.
Application In the measuring extruder , the sample material is plastified under practice-oriented conditions and extruded through the die head. All measuring values such as torque, melt temperature, melt pressure are recorded continuously and represented in the form of tables and diagrams parallel to the current test. The extrudate is tested for various criteria:
• Uniform plastification, gloss, gels
• Color dispersion and color matching
• Transparency and formation of streaks, e.g. with transparent materials
• Swelling and contraction behaviour
• Segregation of individual recipe components of a compound at the die and/or at the screw`s tip
(e.g. titanium dioxide)
• Output per unit of time, etc.
Drive device It is mainly used to complete the plastic plasticizing and transportation by uniform rotation for torque setting,Servo motor control screw torque, pre-set torque from touch-screen. Feeding device Material depend on its own gravity from the hopper into the screw barrel .According to the properties of material production and processing technology conditions, adjust the volume of feed speed and extrusion in order to achieve the balance. Barrel It contains materials and screw.
Screws For each measuring extruder, different screws are available.The screws are made of special steel, the flight basis and the lands are chromium-plated. Single- and multi- stage screws with various compression ratios and different lengths are available for testing a large range of materials.
