Explanation

The degree of difficulty of propellant or explosive decomposition, combustion, explosion, etc. under external action. The sensitivity of propellant and explosive is an important factor that determines whether propellant and explosive can be applied in practice. On the one hand, propellant and explosive will inevitably encounter many unexpected external effects during manufacturing, transportation, use and storage, such as collision, vibration, heating, flame, etc. Under these external effects, propellant and explosive should not have explosion. On the other hand, when propellant or explosive are used, they are required to be able to ignite or detonate reliably under the predetermined external action, that is to say, they should have appropriate sensitivity.
