The working principle of the room of the lacquer that bake

Paint room is generally used for spraying and baking products paint, therefore, paint room the most accurate description should be "spray paint room". General spray paint baking paint do object surface treatment, dust-free grinding.

When painting, the outside air is filtered by the primary filter screen and sent to the roof by the fan, and then filtered and purified by the top filter screen twice before entering the room. The air in the room adopts full drop type, and flows downward at the speed of 0.2-0.3m/s, so that the paint mist particles can not stay in the air after painting, and are directly discharged out of the room through the bottom outlet. This constant circulation conversion, so that spray painting room air cleanliness of more than 98%, and into the air has a certain pressure, can form a constant airflow around the car to remove excessive paint, so as to maximize the quality of paint.

When baking paint, adjust the damper to the position of baking paint, hot air circulation, the temperature in the oven quickly rises to the predetermined drying temperature (55℃ - 60℃). After the initial filtration of the external fresh air, the fan will exchange heat with the thermal energy converter and send it to the gas chamber on the roof of the baking paint. After the second filtration and purification, the hot air through the inner circulation of the damper, in addition to sucking in a small amount of fresh air, most of the hot air is continued to be heated and used, making the temperature in the baking paint room gradually rise. 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 start, so that the temperature in the paint room remains relatively constant. Finally, when the paint time reaches the set time, the paint room automatically shuts down and the paint is finished.
