Cleanroom spray painting booths are commonly used for applying and baking furniture paint. Therefore, the accurate description should be simply "Spray Painting Booth." During painting, external air is filtered through a coarse filter by a fan and directed to the roof, where it undergoes secondary purification. It then passes through an upper filter net into the room. The indoor air falls completely, flowing downward at a speed of 0.2-0.3 m/s, ensuring that the colored paint particles from the spray do not linger in the air but are directly exhausted through the lower air outlet. This allows the purity of the air within the booth to reach above 98%, and the incoming air maintains a certain pressure, creating a steady airflow around the vehicle to remove excess paint, ensuring high-quality finishes.
What safety considerations should be taken into account for a dust-free painting room?
1) Since the paint spray room is a specialized piece of equipment, it requires personnel trained specifically to operate, shut down, and monitor it.
2) Consider eliminating static electricity in the description. As most filtering materials are fibrous products filtered out from the intake and exhaust ports of paint spray rooms, during the process of blowing dust, the filtering materials accumulate a large amount of dust. Under the power of the fan, more static electricity and discharge will be generated due to collision. Without a static eliminator, it can only lead to fires and explosions. If the outdoor exhaust channel exceeds the height of the building, lightning protection measures must also be considered.
When describing lighting in a color space, the selected lamps and switches should be explosion-proof to avoid the risk of ignition.
4) The fan should be an explosion-proof fan, and the fan noise must not exceed the cost.
5) Opt for cost-effective and practical exhaust fans that meet the qualification requirements; the air supply volume of the fan should be 10% higher than the exhaust volume to ensure a slight positive pressure within the color space.
6) Filters and exhaust system dye cleaners must be cleaned promptly to prevent damage to the system's working environment. Establish robust maintenance principles and hire specialized personnel for maintenance.
