Solid Energetic Materials Stability Tester

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.

Technical Parameters

Accessoriess

1. Test chamber assembly (compatible with multi-unit synchronous testing)

2. Solid energetic material sample holder (for positioning and securing samples within the test chamber)

3. Multi-unit connection cable (enabling interconnection between up to 4 units and a single unit)

4. Spare built-in thermal protection element (a spare part to ensure temperature safety)

5. Spare overpressure detection sensor (a spare part to maintain pressure detection function)

6. Communication connection cable (supports remote communication)

7. Test chamber seal (ensuring the sealing performance of the test chamber)

Test Procedures

1. Experimental Preparation: Check the instrument status and install the test chamber components; fix the solid energetic material sample in the test chamber using the sample holder and seal the test chamber.

2. Equipment Connection: If multi-unit testing is required, connect up to 4 units to the unit using unit connection cables; connect the communication cable to prepare for remote monitoring.

3. Parameter Setting: After powering on, set the experimental parameters (including temperature range, experimental duration up to 5 levels, and temperature gradient) on the instrument interface.

4. Start-up and Operation: After confirming the parameters are correct, start the instrument and enable real-time monitoring; remote observation can be performed during the experiment via remote communication.

5. Safety Assurance: During the experiment, the instrument's built-in thermal protector and overpressure detection function will automatically operate to ensure experimental safety.

6. Experimental Completion: After the experiment is completed and the instrument has cooled and depressurized to a safe state, shut down the equipment; remove the sample and clean and maintain the test chamber.
