coal dust的用法详解
Coal dust is the name given to a fine dust created when coal is crushed into a powder. It is typically used in the mining industry and in coal-fired power plants, where it can be released into the atmosphere by combustion or industrial processes.
Coal dust is a major cause of air pollution, mainly due to the release of tiny particles of coal which are small enough to be inhaled. These particles can contribute to a range of respiratory problems, including lung cancer, asthma, and chronic obstructive pulmonary disease (COPD).
Coal dust can also be used in other industries. It can be used as an additive in explosives, or as a fuel in certain types of stoves. It can also be used as a weighting agent for building materials.
In addition, coal dust has been used in the manufacture of certain types of paints and varnishes, and in the production of some plastics.
Coal dust can also be used as an abrasive material, and has been used in the past in the polishing of jewelry and the sharpening of blades.
Finally, coal dust is also used in the production of certain types of glass, including leaded glass for stained glass windows.
