The spray booth is the main supporting equipment used in automobile painting. Many factors, such as the quality of automobile painting and spray paint, are directly related to the spray booth. ) is complete, the cleanliness of the room is good, coupled with excellent spraying operation technology, the coating quality is correspondingly good. Therefore, the requirements for the spray booth are spacious and bright, good illumination, and complete air supply and exhaust facilities. It is recommended to have a water cyclone (circulating water) filter device, so that the residual paint mist after painting can be absorbed in the circulating water in time to prevent residues. Paint mist pollutes the environment and damages the health of operators.
There are many forms of spray booths, such as spray spray booths, water cyclone spray booths, dry spray booths, small spray booths and so on. Among them, the spray booth and the water cyclone spray booth have more complete facilities and good safety, but the investment is relatively large. They are mainly used in the painting production line of large and medium-sized automobile manufacturers, and in the painting of automobile repair, color change and refurbishment. , Two types of small spray booths and dry spray booths are mostly used.
①Small-sized spray booth This spray booth is characterized by a simple structure, an exhaust filter device, and a workbench in the room, which is very suitable for car repair painting or painting of parts replaced during car maintenance.
②Dry spray booth The dry spray booth is composed of a chamber body, an exhaust filter device, an exhaust pipe, and a ventilator. It is characterized by simple structure, spacious indoor space, small ventilation and wind pressure, little flying waste of paint during spraying, high coating efficiency, plus dry design, high work efficiency, plus dry design, no circulation Water installation, so there is no need for waste water treatment, so the cost is low. It is mainly suitable for the color change or renovation painting of the whole vehicle.
The disadvantage of the dry spray booth is that there is no water spin filter device, and the cleanliness of the room is poor. For example, the surface of the indoor wall board is easy to be stained with residual paint mist, so it must be removed frequently or regularly to ensure the cleanliness of the room. . Another disadvantage is that when the wind pressure is too high, the residual paint mist drawn away by the wind will gradually block the filter device (filter screen) and affect the ventilation, so the filter screen should be checked frequently. If the blockage is serious, it should be removed in time or Replace in case it affects the quality of ventilation and operation.
Before using the spray booth, check the various indoor facilities, such as the exhaust device, power device, air supply device, etc., and conduct a professional test run, and use it after the test run is normal. In addition, it is also necessary to be equipped with suitable fire extinguishing facilities, such as fire extinguishers and fire extinguishing materials, for emergency use in case of fire to ensure safety. For large dry spray booths, various suitable water supply devices, such as tap water supply devices, rubber or plastic hoses, etc., should be installed for car washing, floor cleaning, water grinding, etc.
