A spray booth is one of the painting booths, and a painting booth refers to a room equipped with a painting machine and performing a painting job. Spraying room also includes powder room, dip paint room, curtain coating room. Spray booth is designed for spraying liquid coatings, the most complex structure and equipment coating room, the coating workshop is the key equipment necessary. With a variety of spraying methods (such as air spray, airless high pressure spray, electrostatic spraying, etc.) combination, and to adapt to the vast variety of changes in the coating, making the spray booth a variety of forms. Painting room in addition to paint room, dusting room, the other coating room structure, the device is simple, the purpose and function of only dust and ventilation (to exclude solvent vapor).
In the law enforcement inspection, the most common is the spray booth. The paint booth is defined as follows: A completely enclosed or semi-enclosed chamber or enclosure designed for spray coating with good mechanical ventilation and lighting. Indoor air flow organization to prevent paint fog, solvent vapor escape outward, and make it centralized and safe introduction of exhaust system. Spray booths include electrostatic spray booths and non-electrostatic spray booths, with dry spray booths and wet spray booths.
Spray booths are divided into large and small size according to size. Large-scale spray booths are generally enclosed enclosing structures. Operators work in the chamber and set mechanical exhaust ventilation systems. Small and medium-sized spray booths are generally semi-enclosed enclosing structures. Operators face the open mouth in the chamber In vitro operation, only the exhaust system.
Paint job safety rules: Large spray booth should set up a multi-point combustible gas detection alarm device, the lower limit of the alarm concentration should be adjusted in the monitored flammable gas concentration (volume) explosion limit of 25%.
Machinery industry standards: large-scale spray booths should be set combustible gas concentration monitoring alarm, the alarm concentration should be adjusted at the lower limit of 25% gas explosion.
In conclusion, it is recommended that a paint booth (including a car spray paint booth) is provided with a combustible gas alarm device, and for safety reasons, it is suggested that a combustible gas alarm device be installed so as to cause a serious explosion after a gas leak occurs.
