Application Case

Conventional self-accelerating decomposition temperature (SADT) testers mostly use water cooling methods, making it difficult to detect nitro compounds and diazonium compounds with rapid heat generation and high decomposition temperatures. In response to these issues, Xiangyi Instrument has upgraded and optimized the CIT27-10S adiabatic self-accelerating decomposition temperature tester, developing the CIT27-20S adiabatic self-accelerating decomposition temperature tester, […]

The oxidation induction time (OIT) is tested by DSC (differential scanning calorimeter). The sample is usually heated to a specified temperature in a nitrogen atmosphere and kept at a constant temperature, and then switched to an oxygen atmosphere. After a period of time, the material begins to oxidize and release heat. This released heat is

For amorphous polymers, the process of polymers changing from an elastic state to a glassy state by cooling, or from a glassy state to an elastic state by heating is called glass transition, and the temperature at which the glass transition occurs is called glass transition temperature. For crystalline polymers, the glass transition refers to

The melting point is the temperature at which a solid changes its physical state from solid or melts into liquid. For a mixture of multiple components, the peaks that emerge are also multiple peaks. Although the absolute values of the internal energy and enthalpy of the system are still unknown, under certain conditions we can

Refers to the process of a substance changing from a low molecular weight to a high molecular weight. The strength of the sample after curing will be higher. “The curing principle is a principle used in the study of the motion of a variable mass system. It means that at any instant, the motion equation

Experimental method: DSC differential scanning calorimetry is a method to test the degree of accelerated aging of plastics in high-temperature oxygen based on the exothermic reaction when the plastic molecular chain breaks.

What is the glass transition temperature? The glass transition temperature (Tg) is an important characteristic parameter of polymers. The glass transition temperature (Tg) refers to the temperature corresponding to the transition from the glass state to the elastic state. The glass transition is an inherent property of amorphous polymer materials and a macroscopic manifestation of
