The Coating room, also known as the coating room or baking paint room, is a special room or space specifically designed for spraying and coating the surface of objects.

Functions and Roles

• Provide a Stable Painting Environment: It can effectively isolate external dust, impurities, etc., creating a relatively clean space for painting operations. This ensures the painting effect and avoids pollutants such as dust adhering to the surface of the object during the painting process, which could affect the smoothness and glossiness of the coating.

• Control the Emission of Paint Mist: Equipped with a good ventilation system, it can promptly discharge the paint mist and volatile gases of organic solvents generated during the painting process, preventing the accumulation of paint mist indoors. This not only ensures that operators have a clear line of sight, facilitating precise painting operations, but also reduces the concentration of combustible gases and minimizes potential safety hazards such as fires.

• Achieve the Baking Function: Some painting booths also have the function of baking paint. By increasing the temperature, it can accelerate the drying and curing speed of the paint, improving production efficiency. At the same time, it can make the performance of the paint coating better, such as higher hardness and better adhesion.

Structural Composition

• Room Body Structure: Generally, it adopts a metal frame structure, such as a steel structure or an aluminum alloy structure, which has good stability and strength. The exterior is usually covered with materials such as color steel plates and galvanized plates, which play the roles of heat preservation, heat insulation, and protection. The room body has good airtightness to ensure the stability of the indoor air flow and the cleanliness of the painting environment.

• Ventilation System: It is composed of an air inlet, an air outlet, a fan, air ducts, etc. An air filtration device is usually installed at the air inlet to filter the air entering the painting booth and remove dust and other impurities. The fan provides power to make the air flow in a specific direction within the painting booth, and discharges the paint mist and exhaust gas from the air outlet.

• Lighting System: To ensure the accuracy and safety of painting operations, the painting booth requires sufficient and uniform lighting. Generally, explosion-proof lamps are used and installed on the top or sides of the room body to provide shadowless and flicker-free illumination, ensuring that operators can clearly see the surface condition of the objects being painted.

• Heating System: For painting booths with the baking paint function, the heating system is an important component. Common heating methods include electric heating, fuel oil heating, gas heating, etc. The heating system can uniformly raise the temperature inside the painting booth and maintain it within the set temperature range to meet the drying and curing requirements of different paints.

• Filtration System: It includes paint mist filtration and air filtration. The paint mist filtration device is generally installed in the exhaust duct of the painting booth to intercept and collect the paint mist particles generated during the painting process, preventing them from being discharged into the atmosphere and causing pollution. The air filtration system filters the fresh air entering the painting booth to ensure the cleanliness of the painting environment.
