Technical Process of TT-DSC300 Differential Scanning Calorimeter
- Oxidation period test of PE, PPR and other pipes
Oxidation induction time (OIT) was measured by DSC (differential scanning calorimeter). The sample is usually heated to the specified temperature and constant temperature under nitrogen atmosphere and then
switched to oxygen atmosphere. After a period, the material begins to oxidize and release heat. The released heat is detected by the sensor, and the induced oxidation time (OIT) is obtained through software analysis. The length of the oxidation induction time is a parameter of the oxidation decomposition resistance of the reaction material, which is still very meaningful. Usually, the parameter must be detected for buried plastic pipes.
- Glass transition test of resin and other materials
For amorphous polymers, when the polymer changes from a high elastic state to a glass state through cooling, or from a glass state to a high elastic state through heating, the process is called the glass transition, and the temperature at which the glass transition occurs is called the glass transition temperature. For crystalline polymers, the glass transition refers to the transition of the amorphous part from the high elastic state to the glass state (or the glass state to the high elastic state). Therefore, glass transition is a common phenomenon in polymers. However, the glass transition phenomenon is not limited to polymers, and some small molecular compounds also have glass transition.
