On August 2, 2004, a particularly serious aluminum powder explosion occurred in the second grinding plant of Kunshan Zhongrong Metal Products Co., Ltd. in Suzhou City, Jiangsu Province. 146 people were killed and 114 were injured. The direct economic loss was 351 million yuan.

At 9:30 am on December 9, 2020, Taiwan’s Kaohsiung Arms Factory extended the regular replacement operation time for the Tiangong II missile engine. A flash accident occurred during the aluminum powder addition. 3 people were injured and the burn area was about 40-60%.

Dust is everywhere in life, especially in industrial production, and the hazards of dust explosion are shocking. Once the dust explodes, it has huge explosive energy, which is easy to cause continuous explosion, which seriously threatens the safety of people and property. There are many types of dust explosions, and aluminum dust explosion is one of them.

Explosion-proof vacuum cleaner

Aluminum powder, commonly known as silver powder, metallic pigment silver powder. Add a small amount of lubricating oil with pure aluminum foil, pulverize it into scaly powder, and make it after grinding. Aluminum powder is light in weight, has great floating power, strong covering power, and has a good effect on light and heat reflection. After treatment, it can also be made into non-floating aluminum powder.

The general-purpose aluminum powder is mainly made of aluminum powder atomized by nitrogen, that is, the molten aluminum is atomized with a nozzle with compressed nitrogen, and cooled into metal powder with nitrogen, and aluminum powders of different particle sizes are classified by a grading system.

Whole machine explosion-proof vacuum cleaner aluminum powder can generally be used for fingerprint identification and fireworks. In addition, the application fields of aluminum powder also include new building materials, chemical industry, military industry, advanced metal pigments, composite materials, refractory materials, anti-corrosion materials, fireworks and firecrackers.

When storing the aluminum powder, it must be sealed and isolated from the air to prevent oxidation. It can be placed in a sealed tank with a storage temperature of 15-40℃. Do not directly expose to sunlight, rain or high temperature.

The power of dust explosion can be seen from the above, so it is best to equip the whole machine with Explosion-proof dust collector!
