Automotive paint booths are generally used to spray and bake product paint, so the exact description of a car paint booth should be "spray car paint booth". Generally, when painting and baking, the surface of the object should be treated in advance, and it should be cleaned without dust.
When painting, the external air is filtered by the primary filter and sent to the roof by the fan, and then filtered and purified by the top filter to enter the room. The air in the room is fully descended and flows downward at a speed of 0.2-0.3m / s, so that the paint mist particles after spraying cannot stay in the air, and are directly discharged out of the room through the air outlet at the bottom. In this way, the circulation is continuously changed, so that the air in the room is more than 98% clean when painting, and the air sent in has a certain pressure, which can form a constant air flow around the car to remove excess paint, thereby ensuring the quality of painting. .
When baking the paint, the damper is adjusted to the baking paint position, and the hot air is circulated, and the temperature in the baking room rapidly rises to a predetermined drying temperature (55 ° C-60 ° C). The fan filters the external fresh air and sends it to the air chamber on the top of the car paint room after heat exchange with the heat energy converter. After the second filtering and purification, the hot air passes through the inner circulation of the damper to remove a small amount of fresh air. In addition, most of the hot air is continuously heated and used, which makes the temperature in the paint room of the car gradually increase.
燃烧 When the temperature reaches the set temperature, the burner stops automatically; when the temperature drops to the set temperature, the fan and the burner automatically turn on again to keep the temperature in the car paint room relatively constant. Finally, when the baking time reaches the set time, the car paint room will automatically shut down and the baking will end.
