Excessive shaking during transportation will cause part of the aluminum powder to separate. Therefore, during use, avoid earthquakes, and avoid explosions caused by contact of flammable objects with aluminum powder. Whole machine explosion-proof vacuum cleaner

Why did the aluminum powder explode?

Aluminum powder is a secondary flammable product in the management of hazardous chemicals. After the particles are dried, the aluminum powder can be suspended in the air to increase the surface in contact with the air and improve its chemical activity. The minimum ignition temperature is 645 degrees, and the minimum ignition energy is 15 mm Joule. When the air concentration reaches 40g/m, it will explode rapidly when encountering a fire source, and a large amount of heat and combustion products will be generated instantly, which will cause the gas, steam, etc. to expand rapidly, causing an explosion result. When the aluminum powder content is too high, the aluminum metal powder rises again, forming a secondary explosion. Whole machine explosion-proof vacuum cleaner.

The aluminum powder exploded.

The explosion of aluminum powder is dangerous.

Aluminum powder will release a lot of heat when burned in oxygen, and its explosion pressure can reach up to 6.3 kg/cm² (equivalent to an increase of 63 tons of weight per square meter per second).

Aluminum powder explosion extinguishing device.

When aluminum powder is found to ignite and explode, it should be extinguished immediately with dry lime powder. Do not use water, carbon dioxide, carbon tetrachloride fire extinguishers, and do not use high-pressure dry powder fire extinguishers. The contact of water with high-temperature aluminum powder will discharge hydrogen, and the pressurized dry powder will lift the aluminum powder into the air, which will intensify the combustion.

During the production and processing of the aluminum powder of the Explosion-proof vacuum cleaner, the Mg-Al powder Processing dust explosion-proof safety regulations must be strictly followed, and it is strictly forbidden to generate fire in the aluminum powder production environment. When the maintenance equipment needs fire operation, the aluminum powder should be completely removed. During the production and repair process, non-explosion-proof tools should not be used, and the equipment and pipelines should not be impacted. In the production of the equipment, strengthen the lubrication and reduce friction. It shall be complete, and shall not be overloaded, short-circuited or disconnected.
