I believe many people have seen explosion accidents in flammable and explosive dust factories such as industrial production. The culprit of this type of accident is mostly “dust explosion”. Why does dust explode? This is what we call static electricity. Static electricity causes dust explosion. Therefore, the vacuum hose used in many industries must be anti-static vacuum hose.
Why does anti-static hose dust explode?
Dust explosion is similar to gasoline explosion. Gasoline is a gas molecule that evaporates into the air. When it reaches a certain concentration and encounters an open flame, it explodes. Dust explosion is very fine dust particles that spread into the air. When accumulated to a certain concentration, it will also explode when it encounters fire like gasoline.
Common flammable dust
Metals, such as magnesium powder, aluminum powder
Grain, such as wheat, starch
