Oxidation period test of PE, PPR and other pipes

Oxidation induction time (OIT) was measured by DSC (differential scanning calorimetry). The sample is usually heated to a specified temperature under a nitrogen atmosphere and held at a constant temperature, and then switched to an oxygen atmosphere. After a period of time, the material begins to oxidize and release heat. The released heat is detected by the sensor and analyzed by the software to obtain the oxidation induction time (OIT). The length of the oxidation induction time is a parameter of the resistance to oxidative decomposition of the reaction material, and it is very meaningful. Usually, buried plastic pipes must be Check this parameter.



Vitrification test of resin and other materials
For amorphous polymers, when the polymer changes from a high elastic state to a glass state by cooling, or from a glass state to a high elastic state by heating up, it is called glass transition, and the temperature at which the glass transition occurs is called glass transition. temperature. For crystalline polymers, glass transition refers to the transition from a highly elastic state to a glassy state (or a glassy state to a highly elastic state) that occurs in the amorphous part of the polymer. Therefore, glass transition is a ubiquitous phenomenon in polymers. However, the glass transition phenomenon is not limited to macromolecules, and some small molecular compounds also have glass transitions.


Material melting point, enthalpy test (thermal stability test)
The melting point is the temperature at which a solid transforms its physical state from a solid state or melts into a liquid state. A mixture of multiple components produces a multimodal peak.


Curing test of glue and other materials
Refers to the process of changing substances from low molecules to high polymers, and the strength of the cured sample will be higher
