The working principle of the dust-free spray booth

The working principle of the dust-free spray booth

As the name suggests, it is to spray paint the filtering and spray paint objects in a room, which is now also called the paint baking room.

Traditional spray painting is to spray paint on appliances (cars, furniture, etc.) in the open air, but this method will reduce the quality of spray paint for large appliances. For example, the dust in the air will be mixed in the paint during the painting process, thereby reducing Paint quality; there is uncertainty in wasting paint, and the painting area will be very dirty; for the staff, it will be very dirty on the one hand, and on the other hand, it will be harmful to the body to inhale a large amount of paint mist. Later, when people wanted to set the spray paint within a certain range, the earliest spray paint booth-the exhaust type spray booth was created. The spray booth in China was first created in the Chengdu area in the 1990s. The three keys to the exhaust spray booth are:

1. Ventilation-the key to the work of the ventilation spray booth

2. Filtration-filter small particles in the air

3. Exhaust-exhaust of waste air and entry of new air

The specific principle is: wind (outdoor air) spray booth filter cotton-spray booth-use spray equipment to spray paint-exhaust fan (discharge the generated paint mist) The weakness of this spray booth is Existence:

1. The filter cloth is easy to scratch and dust is easy to enter

2. Easy to enter the unclean outdoor air

3. Not environmentally friendly, waste paint

4. Frequent cleaning is required, and the dirt on the filter cloth is regularly removed

At present, a new type of paint spraying room has come out --- a full-pressure dust-free paint spraying room, and the principle of the furniture dust-free paint booth in China

 

Widely used in the industry. The basic principle of the full-pressure dust-free spray booth is the same as that of the exhaust-type spray booth, but it uses the directionality of the pressure to spray paint vertically from the top to the bottom to make the painting more precise. In addition, in terms of hardware, there is a host room, where "multi-layer filter cotton" is used instead of filter cloth to achieve high air cleanliness; infrared baking lamps are used to save drying time; when the excess paint mist is discharged, the use of water curtains is more environmentally friendly. In this way, the chance of rework is almost zero, paint is saved, and work efficiency is improved. Because of the use of infrared baking lamps, people now also call the paint room.
