Laboratory Mixer-200c Unit of Torque Rheometer

The Principle of MixerThe 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 .  Technical parameters :      Mixer-20Mixer-60Mixer-200Mixer-300Chamber volume20ml60ml200ml300mlMixer Material630Types of rotorRoller,Banbury,Cam,Delta,Sigma(Roller standard ,others optional )Rotor processingAfter high precision polishing, the surface chromium platingSpeed ratio of rotors3:2Temp control systemRKC from JapanTemperature sensorJ type thermocoupleHeatingElectrical Heating/3 zones, PIDMax.

Different structural type of rotors are suitable for different mixing process and directly affect the products quality ,efficiency and energy consumption. Now, we have developed five kinds of rotors for the plastic and rubber materials ,as illustrated below. The rotors are made of special steel ,counter-rotation towards each other at the speed ratio of 3: 2 provide for excellent compounding and high shear mixing characteristics .      Photo   Name                  Function RollerIt is usually used for testing thermoplastic materials and compounding with additives.     BanburyIt is usually used for testing natural and synthetic elastomers with regard to flow and cure behavior, compounding with additives . CamIt is usually used for testing thermo-plastic polymer, ceramic composites, food and other high-torque materials.  DeltaIt is usually used for testing cross-linking thermo-set polymer . SigmaIt is usually used for testing food, medicine, and plastisol materials, which have low-torque.  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
