The reason why dust becomes "explosive" is because dust has a large surface area. Compared with massive materials, dust has strong chemical activity, large area of ​​contact with air, large number of adsorbed oxygen molecules, and fast heat release process. When conditions are right, if one of these particles is ignited by fire, a chain reaction will occur like an atomic bomb, and an explosion will occur. As long as it is a solid suspension with a particle size less than 75 μm, such as aluminum powder, iron powder, magnesium powder in the metal processing industry, coal mining will occur in coal mining, starch, corn and wheat flour in food, etc., as well as wood powder, plastic powder and Paper scraps, etc., will cause dust explosions, and the power of these explosions is not small!
