About inflator production

Propellant safety manufacturing process: From strict raw material control to explosion-proof mixing and compaction

The propellant is made by mixing sodium azide with an oxidizer, where the role of the oxidizer is to promote the combustion reaction of sodium azide when it is ignited. Sodium azide is supplied by external vendors and must undergo strict inspection before entering the production process to ensure that its quality meets relevant standards and technical requirements. Once it passes inspection, sodium azide is stored in secure storage facilities until it is needed for production.  

At the same time, the oxidizer is also provided by external suppliers and undergoes quality inspection and standardized storage upon receipt. Different manufacturers may choose different types of oxidizers during production to meet their respective technical requirements.  

During the production phase, sodium azide and the oxidizer are taken from the storage system and mixed under the precise control of a sophisticated computerized process control system. Due to the potential risk of explosion in this process, explosive handling operations must be carried out within specially designed isolation bunkers to ensure production safety. If safety sensors detect sparks or abnormal conditions, a high-speed flooding system will be immediately activated to perform emergency suppression by rapidly injecting water into the entire workspace.  

In addition, production is usually carried out in multiple independent small production units with redundant configurations. This layout can prevent overall production interruption in the event of a local incident, causing only a temporary decrease in production capacity, thereby ensuring the continuous operation of the production system.  

After mixing is completed, the propellant mixture is transferred to the storage system. Subsequently, it is compressed using pressing equipment so that the propellant ultimately forms solid shapes in the form of discs or granules to meet the requirements for subsequent use or assembly.
