What are the disadvantages of air aluminium powder?

Do you know the disadvantages of air aluminium powder? It is well known that air aluminium powder, like spherical aluminium powder, is a type of powder coating. As long as it is powder, there is a potential source of danger, which can cause danger or even explosion due to certain environmental factors. However, do you know that air aluminium powder is far more dangerous than spherical aluminium powder? Do you want to know more about the hazards of air aluminium powder? Let me briefly introduce it to you.

What are the disadvantages of air aluminium powder? According to my understanding, air aluminium powder is a silver-white powder with no odor and a metallic luster. It is made by adding a small amount of lubricant to pure aluminium foil, and then crushing and grinding it into flake powder, and finally polishing it. Air aluminium powder is produced through air atomization process. Therefore, if it combines with air in a certain medium, it can cause explosions and other consequences. So what are the other disadvantages?

In addition to the risk of explosion, high concentration of air aluminium powder can also irritate the respiratory mucosa. Contact with small dust particles generally does not cause irritation to the eyes, but large particles can cause some frictional irritation. If the normal dosage that enters the oral cavity in the workplace does not cause toxic reactions, but ingesting a large amount of dust can cause frictional irritation to the gastrointestinal tract.

However, it is impossible to completely eliminate the production of aluminium powder. According to my understanding, air aluminium powder is widely used, mainly in paints, inks, pigments, fireworks, and can also be used as an additive in porous concrete. In addition, air aluminium powder can also be used in the treatment and pharmaceutical industry, automotive and aviation industry, etc.
