Description

Technical Field

[0002] Thermal analysis is an experimental technique performed at a program-controlled temperature. It studies the various physical and chemical changes of a substance during heating by measuring the relationship between the physical properties of the substance under specific conditions and the temperature. This method can be used to determine the crystal transformation, melting, evaporation, dehydration and other phenomena of the substance, and can also be used to study chemical changes such as thermal decomposition and oxidation. During the thermal analysis of materials, different materials may require different fixation methods, and the specific choice depends on the experimental conditions and material properties.

The hanging method easily causes the heat-broken materials to scatter inside the thermal analysis instrument, which is difficult to clean. The shape of the heating mold is fixed, and different materials need to be replaced with different molds for material security. The operation is cumbersome and the equipment cost is high.
