Do you know the potential drawbacks of air aluminum powder? As we all know, both air aluminum powder and spherical aluminum powder are types of powder coatings. And just like any powder, they pose a hidden hazard—anytime, under certain environmental conditions, they could trigger a dangerous situation or even an explosion. But did you know that air aluminum powder is far more hazardous than its spherical counterpart? Curious to learn about the additional risks associated with air aluminum powder? Let Xuyang’s editor provide a brief introduction—let’s dive in together!
What are the drawbacks of air aluminum powder? As far as I know, air aluminum powder is a silvery-white powder that is odorless and has a metallic sheen. It’s produced by adding a small amount of lubricant to pure aluminum foil, then crushing and pounding it into a flaky powder before finally polishing it into its final form. Air aluminum powder is created using an air atomization process, which means that when combined with air in certain conditions, it can lead to explosive consequences. But are there any other potential hazards associated with this material?
Besides the danger of being explosively flammable, high-concentration airborne aluminum powder can also irritate the respiratory tract's mucous membranes. While contact with tiny particles typically causes no irritation to the eyes, larger particles may induce some frictional irritation. Although ingesting normal levels of these particles in a workplace setting generally doesn’t result in toxic reactions, swallowing significant amounts of dust could lead to abrasive irritation of the gastrointestinal tract.
However, completely eliminating the production of aluminum powder is also impossible. As far as I know, air-blown aluminum powder is widely used—primarily in paints, inks, pigments, and fireworks—but it can also serve as an additive in porous concrete. Beyond these applications, air-blown aluminum powder finds use in pharmaceuticals, medical products, automotive industries, and more.
That’s all for today’s discussion on "What Are the Drawbacks of Air-Aluminum Powder?" We hope it was helpful—see you next time!
