Description

Technical Field

[0001] The utility model relates to the technical field of thermal stability measurement, in particular to a device for measuring the thermal stability of polymer materials. Background Art

[0002] Thermogravimetric analyzers are widely used in polymer material research, such as material performance evaluation, polymerization reaction kinetics research, and additive effect evaluation. When a polymer material sublimates, vaporizes, releases gases, or loses water of crystallization during heating, its mass changes. The thermogravimetric curve is not a straight line but instead shows a downward trend. By analyzing the thermogravimetric curve, we can determine the temperature at which the measured substance changes, and based on the weight loss, we can calculate the amount of material lost. However, when not in use, dust can easily enter the equipment through the ceramic crucible, making it difficult to remove. Furthermore, the crucible typically has two sealing heads, which need to be removed one by one, which is cumbersome and laborious. Utility Model Content
