Everything about the spray booth you want to know is here
Many people know that the paint booth mainly refers to the place where the surface of the object is painted with paint and dried. However, I believe most people don't know much about the structure, working principle, system composition and price of the paint booth. Today, I will come to a more systematic and comprehensive introduction to the spray booth. The knowledge about the spray booth you want to know is basically here. Come and learn!
1. Structure of spray booth
The general paint room adopts the assembled structure, the house body adopts the mother-inserted thermal insulation sprayed wall board, and the sealing and heat preservation performance are good. The side of the house body is equipped with a work door, which is convenient for the staff to enter and exit, the aluminum alloy covered door and the center of the door are installed. Observation window, you can observe the dynamics of the room at any time, the auxiliary equipment in the paint room is also endless, the use rate is higher: fan, burner, lighting, bottom plate, filter cotton, electric control box, generating room, paint lamp, high efficiency Thermal energy converters, etc., of course, the specific configuration and model depends on the overall planning of the automotive service organization.
2. Working principle of painting
When painting, the external air is filtered by the primary filter and sent to the roof by the fan, and then filtered through the top filter to be purified. The air in the room is fully descended and flows downward at a speed of 0.2-0.3 m/s, so that the paint mist particles after painting cannot stay in the air, and are directly discharged outside the room through the bottom air outlet. In this way, the circulation is continuously changed, so that the air in the room is more than 98% clean when painting, and the air that is fed has a certain pressure, which can form a constant airflow around the car to remove excess paint, thereby maximizing the guarantee. The quality of the spray paint.
3. How does baking paint work?
When baking paint, the temperature is raised by an infrared electric heating device that is automatically controlled. The infrared baking lamps are evenly distributed around the spray booth. At this time, the inner circulation damper is opened, and the inner circulation fan is started, generating a top-down airflow to uniformly raise the temperature inside the room. When the temperature in the baking room reaches the preset baking temperature, the automatic electronic control system starts to work, so that the infrared heating baking lamp stops working. When the temperature drops 4-5 °C, the baking lamp works again, so that the indoor temperature is maintained until the temperature is maintained. Set the working time to finish the job.
Note: Infrared heating: Generally, organic coatings have a strong absorption capacity for infrared rays, especially far infrared rays. Therefore, the drying effect of infrared rays on the layers is very remarkable. The layer is cured quickly, the quality is good, and there are no defects such as pinholes and bubbling.
4. System composition of spray booth
(1.) Wind circulation system
The air circulation system consists of a complete set of units. The unit is equipped with a set of fans. The air is supplied by two 3KW fans. The total air volume is 24,000 square meters, which makes the room wind wind speed >0.3m/s, thus ensuring rapid indoor air circulation. No paint residue remains, ensuring the operator's health and painting effect. The fan adopts the spray-painting and air-conditioning fan of the paint room produced by Siemens technology. It has compact structure, low power consumption and stable performance.
(2.) Air purification system
The filter system adopts two filter layers. The coarse filter layer effectively captures dust particles larger than 10um in diameter. The high-precision high-efficiency filter layer has a multi-layer structure, which can effectively capture dust particles larger than 4um in diameter and the dust holding capacity of the entire filter system. Large, low resistance, long life, filtration efficiency can exceed 98%.
(3.) Paint mist treatment system
The paint mist treatment adopts water filtration, the use cost is low, the paint mist is ideally adsorbed, and the effect is good. The indoor noise complies with GBJ87-85 "Industrial Enterprise Noise Control Design Specification" and does not exceed 85 decibels. The current development status and working structure principle of spray booth in China.
5. The price of spray booth
The price of low-end domestic paint booths ranges from 22,000 to 60,000, and the high-end price ranges from 6 to 150,000. The main types of circulation are: outdoor rain-proof paint room, fuel-type high-temperature paint room, teaching spray paint room, large-channel paint room, environmental paint room, infrared paint room and standard paint room, etc., with different functions.
