Why Aluminum Aluminium Powder And Dust Explosion And Dust Explosion?
Aug 31, 2016

What is aluminium powder: also called silver, alias aluminum silver, good heat transfer properties. Fire danger of aluminum is that dust is mixed with air, if Mars will explode and burn. Mixture of aluminum powder and other antioxidants can also form explosive mixtures. If contact with the acid, alkali produces hydrogen, hydrogen is also easy to fire and explosion in the air.

The Kunshan zhongrong metal products Co Ltd when the cause of the blast has been identified is in polished aluminum alloy wheels produce a lot of aluminum powder, dust encountered fire aluminium dust explosion and dust explosion accidents occurred, causing enormous human casualties.

Aluminum polishing there are many. Is usually tied with a polishing cloth wheel thrown, so then we have a lot of aluminum dust. Aluminum alloy processing factory is typically on the edge polishing machine with a great exhaust dust suction device. Aluminium powder and dust won't be so many gathered.

Aluminum powder is the secondary water lighted objects react with water, producing hydrogen and produce heat. Sometimes will encountered dry of aluminum powder occurred explosion, this is because particles very tiny of dry Aluminum powder can suspended in air in the, increases has and air of contact surface, makes its chemical activity increased, once dust in air in the reached must of volume Shi, encountered with fire, can quickly deflagration, moments produced large of heat and burning product, makes gas, and steam, dramatic expansion, caused explosion of consequences.

When the concentration of the explosive concentration after the interval, by certain effects of ignition energy, it will explode, Aluminum powder, may lead to aluminium powder once again raised, forming secondary explosions, called sympathetic detonation.

Aluminum powder can also explode, it is estimated that many people do not know. Specifically, the polishing job for a long time makes a lot of aluminum powder in the air of the workshops, and aluminum Burns at quite low, if he met with fire or high temperatures, friction, is likely to explode.

Aluminum will react with water to generate hydrogen, which is the reason not use water to put out fires. Have happened before with water to extinguish an aluminum explosion fire, triggering explosive example again.

Aluminum powder explosion caused the fire cannot use water, foam fire extinguisher should be used to put out fires (aluminum). Through the foam cover, fire and air. This is because the aluminum will react with water to generate hydrogen, not cause of water used to put out fires. Have happened before with water to extinguish an aluminum explosion fire, triggering explosive example again. Most people do not know that aluminum can also explode, especially jobs makes job of polishing plant for a long time a lot of aluminum powder in the air, and aluminum Burns at quite low, if he met with fire or high temperatures, friction, is likely to explode.

Aluminum dust of characteristics: in air in the encountered smaller of with fire that can fire burning; in air in the dip has oil of aluminum powder, as long-term heap store, set hot not bulk, also easy caused spontaneous combustion or explosion, and Aluminum powder of particles degrees more small explosion risk more big, dang its in air in the concentration reached 40 grams/M3 above Shi, met fire that can explosion. High flame temperature, burning speed, explosive power, strong radiant heat. Burns, a green-blue flame, emit white light, blast pressures up to 6. 3 kg/cm 2. On surrounding buildings and security with greater damage and harm.
