Thermomechanical analyzer TMA 402 F1/F3 Hyperion
Product details
TMA402F1/F3 Hyperion®The latest thermal mechanical analyzer launched by Nike can effectively analyze the thermal mechanical/thermal expansion characteristics of samples under certain loads. The maximum sample length is 30mm and the maximum force is 3N. The built-in high-precision force sensor ensures precise and controllable force within the mN range.
Digital Displacement Sensor (LVDT) - TMA 402 Hyperion®The core
This is a time tested technology that is also used in thermal expansion instruments. It has extremely high accuracy and can measure size changes at the nanometer level (with a digital sensitivity of 0.125nm).
Vacuum sealed constant temperature system
TMA 402 Hyperion®The measurement system is maintained at a constant temperature through a water bath, so the thermal radiation from the furnace body and the temperature fluctuations in the surrounding environment will not affect the system.
In order to ensure a pure atmosphere for measurement and the vacuum degree of the instrument, all units in the instrument are designed to be vacuum sealed. TMA 402 F1 uses a turbo molecular pump with a vacuum degree of up to 10-4 mbar. When combined with MFC (mass flow controller, optional in TMA 402 F3), the required pure atmosphere for testing can be selected during the measurement process, such as inert gas or oxidizing gas.

Synchronize measurement of force and displacement signals
TMA 402 Hyperion®In the system, the force applied to the sample is controlled electromagnetically, so the system can quickly detect changes in load during the testing process (such as creep mode). Unlike instruments that can only pre-set the applied force, TMA 402 Hyperion ® Sensors with medium to high sensitivity (sensitivity<0.01mN) monitor the applied force in real-time through a push rod, and then automatically adjust it as needed.
Accurately control the applied force
TMA 402 Hyperion®The electrical control system can control the applied force with mN accuracy. With this high-precision control force, even testing of fragile materials such as fibers and films can be carried out smoothly; At the same time, the force can be controlled through software to change in a stepwise or linear manner, making it particularly convenient to test creep and compression modes; In addition, TMA 402 Hyperion®Additional features are also provided, including a variety of pulse options, such as rectangular and ramp shaped single frequency or multi frequency oscillation forces (frequency up to 1Hz, optional). In this mode, some viscoelastic properties of the material can be easily characterized, such as elastic modulus and creep modulus.

TMA 402 F1/F3 Hyperion®-Application examples
Material characterization at low temperatures
Tensile measurement of polymer films
Apply force to the film, measure its tensile deformation, shrinkage deformation, and anisotropy. In this example, we measured the stretching and shrinking phenomena of a polycarbonate film with a thickness of 40 μ m in the stretching mode. Due to different forces, the results also vary greatly. When a small force is applied (5mN), the film shrinks at high temperatures, while when a larger force is applied (50mN), the film undergoes expansion deformation.

Measurement of residual deformation caused by compression of sealing materials
It is crucial for sealing materials to be able to return to their original state after continuous application of force. To measure this property, we applied a force of 3N to a certain elastic sealing material, which was then reduced to 5mN for 40 hours. It was observed that the compression was 21%. After removing the force, the compression recovered by 16.2% after 30 minutes and 16.8% after 60 minutes. After 30 hours, the material did not return to its original state and still had residual deformation, which was due to the viscoelastic properties of the material.
Characterization of viscoelasticity of polytetrafluoroethylene
By combining the three-point bending mode with oscillatory forces, the viscoelasticity of a given material can be characterized. Apply a rectangular modulation force (composed of a static force of 0.2N and three different dynamic forces) to the PTFE rod between -150 ° C and 150 ° C. Based on the structural characteristics and expansion coefficient of the sample, the corresponding relationship between its storage modulus E and temperature can be calculated. At the same time, three typical changes of polytetrafluoroethylene can be observed: β transformation at -100 ° C, crystal transformation from 0 ° C to 50 ° C, and glass transition at 100 ° C.
Material characterization at high temperatures
Sintering of Aluminum Titanate
In the automotive industry, aluminum titanate is used as a carrier material for catalytic converters. The following figure shows the test of aluminum titanate body between room temperature and 1450 ° C. At the end of the test, the aluminum titanate was kept at a constant temperature of 1450 ° C for 7 hours. The results showed that during the heating process, the sample shrank by 12.7%; The sintering process is divided into two steps, with the larger one having a sintering rate of 0.31%/min; In the constant temperature range, the sample further contracted by 0.6%. Naichi also provides rate control sintering software (RCS option), which can further optimize the sintering process.
Analysis of volatile products
The commonly used testing method for clay and powder samples is TMA-MS (A ë olos)®）Used in combination, the temperature range is from room temperature to 800 ° C. The sample first releases adsorbed bound water and interlayer water (shrinkage of 0.01%); At 300 ° C, organic components begin to burn (peaks appear on the curves of m18 (H2O) and m44 (CO2)), but due to their low content, they have no significant effect on the expansion curve; Between 487 ° C and 536 ° C, the mineral components in the clay dehydrate, with a corresponding shrinkage of 0.05% in the spectrum.
