Car spray paint room work process

- Apr 22, 2020-

The paint room is generally used for spraying and baking car paint, so the most accurate description of the paint room should be "spray paint room".

When spray painting, the outside 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 adopts the full-fall type, and flows downward at a speed of 0.2-0.3m / s, so that the paint mist particles after painting cannot stay in the air, and are directly discharged out of the room through the bottom air outlet. This constantly circulates and converts, so that the cleanliness of the air in the room is more than 98% when spraying paint, and the air sent has a certain pressure, which can form a constant air flow around the car to remove excess paint, thereby ensuring maximum The quality of the paint.

When baking paint, adjust the damper to the baking paint position, hot air circulation, the temperature in the baking room quickly rises to the predetermined drying temperature (55 ℃ -60 ℃). After the initial filtering of the external fresh air by the fan, the heat exchange with the heat energy converter is sent to the air chamber at the top of the paint room, and then the second filtering and purification. Most of the hot air is continuously heated and utilized, causing the temperature in the paint room to rise gradually. When the temperature reaches the set temperature, the burner automatically stops; when the temperature drops to the set temperature, the fan and the burner are automatically turned on again to keep the temperature in the paint room relatively constant. Finally, when the paint baking time reaches the set time, the paint baking room automatically shuts down and the paint baking ends.
