Solid Energetic Materials Stability Tester
Category：Battery Safety Tester
Introduction
The Solid Energetic Materials Stability Tester monitors the changes in gas pressure over time during the thermal decomposition of solid materials (such as explosives and propellants) in a tightly sealed reaction vessel under isothermal heating conditions in real time and continuously. This method can accurately and repeatedly test the chemical instability of energetic materials caused by impurities that compromise their stability, incompatibility with surrounding substances, or aging, thus precisely characterizing the thermal decomposition reaction characteristics of energetic materials and scientifically assessing their thermal stability and storage life.
Applications
The Solid Energetic Materials Stability Tester is primarily used to assess the stability of solid energetic materials (such as explosives and propellants) under conventional storage and transportation conditions. It accurately characterizes the thermal decomposition reaction characteristics of materials by continuously monitoring the changes in gas pressure over time during the thermal decomposition of solid materials within a tightly sealed reaction vessel under isothermal conditions, thereby scientifically evaluating their thermal stability and storage life.
