Characteristics of dust (Particle Characteristics)
dust (Particle Matter) means particles of solid or liquid suspension in the air or gas. If it's a small particle called the roso (Aerosal).The dust caused by the factories are often caused by the process of combustion and production processes will look different: the size of the dust. Quantity or concentration, shape, density and other properties, such as electrical. Moisture absorbent (Hygroscopic). The wong susceptible reaction (Reactivity), poisoning (Toxiclity), etc. In terms of air pollution control. The key features of dust or particles (Particle Size) size is mostly the roso has various sizes ranging from 0.001 to 100 micron. Small dust is dust that is le than 1 micron 10 micron-1 is in the middle of Khanak, and 10 100 is large, the size of micron-range up to 1 micron dust 10 micron size of dust that are important in controlling air pollution took. .In addition, the dust that is smaller than or equal to 10 micron Dust Reapirable I know that which when breathed into the body will cause harm health. Best dusts that are smaller than 1 micron Submicron Particles called.
