[0002] Coating is the process of covering metal and non-metal surfaces with a protective or decorative layer. There are various coating methods. Coating plays a certain protective role, protecting objects such as metal, wood, stone, and plastic from corrosion by light, rain, dew, water, and various media, thereby extending the service life of the objects. At the same time, coating also has a decorative function. Through coating, we can make objects more beautiful and shiny, and improve the overall quality of products. After the coating is completed, in order to make the coating on the surface of the parts dry and cure quickly, the parts also need to be dried. Drying can ensure the quality and stability of the coating. The drying operation is generally carried out in a drying room.
