Work process of automobile environmental protection spray booth

    The environmentally friendly car paint booth is a device for spraying and baking car paint. When the car paint booth is in use, it adopts mechanical control, which can save space and is convenient to use. At the same time, the car paint booth can force the primer and topcoat to dry , To speed up the pace of work, improve work efficiency and coating quality. The following is a detailed introduction to the work process of the car paint booth.

    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 adopts a full-down type, with a speed of 0.2-0.3m/s. Flow down, so that the paint mist particles after painting can not stay in the air, but are directly discharged out of the room through the bottom air outlet. In this way, the continuous cycle conversion makes the air cleanliness in the room reach more than 98% during painting, and the air is sent in. The air has a certain pressure, which can form a constant airflow around the car to remove the excess paint, so as to maximize the quality of the spray paint.

    When baking the paint, adjust the air door to the paint position, and the hot air will circulate, and the temperature in the baking room will quickly rise to the predetermined drying temperature (55℃-60℃). The fan will initially filter the fresh air from the outside and exchange it with the heat converter. It is sent to the air chamber on the top of the paint room, and then filtered and purified for the second time. The hot air passes through the internal circulation of the damper. In addition to sucking in a small amount of fresh air, most of the hot air is continuously heated and used, making the temperature in the paint room gradually Increase. When the temperature reaches the set temperature, the burner automatically stops; when the temperature drops to the set temperature, the fan and the burner automatically turn on again, so that the temperature in the paint room remains relatively constant. Finally, when the paint time reaches the set temperature At time, the paint booth will automatically shut down and paint will end.
