Magnesium powder is flammable and explosive, and it is easy to generate dust during the production process. Once the dust concentration reaches a certain level, it may cause an explosion when it encounters a fire source or high temperature, causing serious damage to personnel and equipment. In order to reduce risks and ensure production safety, the safety monitoring system is an indispensable and important part of the process production line of passivated magnesium powder.

In addition, the existing safety monitoring system often neglects to track and monitor the safety status of raw material transportation and process production line processes, and relies more on manual experience, which is prone to misjudgment and omission.
