If you want to start – a car repair company or repair shop, then you need to understand in detail and configure the corresponding painting equipment, this article will introduce the elements and considerations related to the configuration of painting equipment, so that you can make more effective use of funds on hand, to achieve good value for money, value for money.
- How to configure a paint booth
A paint booth is an important piece of equipment that is indispensable for automotive refinishing and painting operations. The purpose of a paint booth is to provide a safe, clean, and well-lit place to paint cars.
The purpose of the paint booth is to provide a safe, clean and well-lit environment for the painting work so that the painting work is not disturbed by dust and the quality of the paint is guaranteed.
The spray booth is designed to provide a safe, clean, and well-lit spraying environment for car painting construction so that the spraying work is not disturbed by dust, the quality of the paint is guaranteed and the volatile paint mist is controlled in a limited space to minimize environmental pollution.
- Technical requirements of the paint spray booth
① The air entering the spray booth must be strictly filtered to ensure that there is no dust in the air.
② Airflow in the spray paint room must flow along the direction of gravity from the ceiling to the ground, and from the ground to discharge the air, and after filtered to make it cleaner air.
③ Ensure that the air in the spray booth is converted 2 times per minute, therefore, the indoor airflow rate should be 0.3-0.6/s.
If the airflow rate is too large, the paint loss will be too much and the state of the coating will be poor; if the airflow rate is too small, it will affect the normal evaporation of the solvent.
④ To have good lighting conditions.
⑤ Ensure that there is no negative pressure in the paint spray booth. This can be achieved by controlling the intake and exhaust volume, the amount of air entering the paint booth should be slightly more than the exhaust volume.
⑥ The operational noise of the paint spray booth must not exceed 85dB.
⑦ Must comply with the relevant requirements set by the fire prevention department.
