Adiabatic Calorimeter

Uses

The Adiabatic Calorimeter simulates an adiabatic environment and real-time monitors the thermal behavior of chemical substances to accurately calculate key thermal safety indicators such as TD24, TMRad, and SADT. It provides robust technical support for the safe production in the chemical industry and the development of new materials.

• Accurately simulates adiabatic conditions to ensure the authenticity of test results.
• High-precision sensors capture minute heat changes, ensuring reliable data.
• Wide temperature measurement and control range to meet the testing needs of various samples.
• Real-time monitoring of multiple parameters for a comprehensive understanding of the sample’s reaction state.
• Chemical safety assessment to effectively prevent the risk of production accidents.

Working Principle

The Adiabatic Calorimeter achieves its adiabatic condition by adjusting the furnace temperature to match the temperature of the sample cup’s outer surface, thereby controlling heat loss. This ensures that there is no temperature gradient between the sample cup and the environment, and thus no heat flow. During testing, the spherical sample cup containing the sample is placed at the center of the heated furnace, with the furnace temperature precisely regulated by the temperature control system. The sample cup can also be connected to a pressure sensor for pressure measurement.

The Adiabatic Calorimeter can simulate the most stringent closed conditions and accurately measure the decomposition heat of substances. By analyzing the temperature-time (T-t) curve, the initial decomposition temperature t₀ and the final temperature T_f can be determined. The adiabatic temperature rise (ΔTad,d) can then be directly calculated. Through thermodynamic studies of the decomposition reaction, the adiabatic temperature rise rate equation can be obtained, which allows for the calculation of data such as TMRad and TD24.
