(1) configuration of spray paint
1) configuration purposes. The spray paint is one of the most important equipment for the auto repair and painting operation. The purpose of equipment spray room is to provide clean, safe and well lit painting environment for vehicle painting construction, so that spraying construction is free from dust interference, ensuring the quality of paint spraying, and limiting the volatile paint mist in limited space to reduce environmental pollution.
2) technical requirements for spray paint. (1) the air entering the spray paint must be strictly filtered to ensure that there is no dust in the air. (2) the flow of air between the spray paint must flow from the ceiling to the ground in the direction of gravity, and the air is discharged from the ground and filtered into a cleaner air. (3) to ensure that the air between the spray paint is converted 2 times per minute, so the indoor air velocity should be at 0.3-0.6/s. The excessive air velocity, excessive coating loss, poor coating state and too small air flow velocity affect the normal volatilization of the solvent. (4) good lighting conditions. Ensure that there is no negative pressure in the spray paint. It can be achieved by controlling the intake and exhaust volume, and the amount of air entering the spray paint should be slightly more than that of the exhaust. The working noise of the paint does not allow more than 85dB. Complies with the requirements of the.
3) classification of spray paint. Two types of spray paint can be divided into dry and wet types according to their different ways of removing paint fog and preventing dust mixing. (1) dry spray paint. The dry spray paint is mainly composed of the chamber, the filter, the exhaust pipe and the ventilator. Its characteristics are simple structure, low loss of paint and high coating efficiency. Because water is not used, water treatment equipment is reduced, and its cost is low. It is widely adopted by small and medium-sized repair enterprises in China. (2) wet spray paint. Wet spray booth and spray type, drencher, paper type and rotary type four. For the coating of top grade automotive finish, it is seldom used in home and abroad.
4) the maintenance of the spray paint. All the preparatory work before the spray painting should be carried out outside the spray paint. The filter must be checked regularly and replaced at the specified time. (3) check the readings of the barometer every day, grasp the air pressure range between the spray paint, and strictly prohibit negative pressure. (4) dry spray between the surface of the ground before spraying in order to prevent dust. Check the lighting situation regularly and replace the lamps which are weak or burned.  The regular lubrication and maintenance of fan and motor. Pay attention to personal hygiene, dressed in dirty clothes into the cabin is strictly prohibited.  Every time after the end of the coating operation, should be thoroughly cleaned, and related equipment maintenance and cleaning spray paint room.

(2) the configuration of the lacquer house
1) configuration purposes. The car spraying construction, from the customer's perspective and maintenance business point of view, hope to paint dust state as soon as possible, one of the reasons is to improve efficiency, save time, but the main reason is to ensure the coating effect, if the surface is not dry, will greatly increase the possibility of dust attachment.  2. To ensure the comprehensive performance of the paint after coating. If you only require quick drying, we can choose the type of quick repair paint, but considering the coating quality and paint should pay attention to the comprehensive performance of all aspects, not only the pursuit of quick drying and no matter how its performance, therefore, the best solution is to configure the paint room.
2) the technical requirements for the paint house. There must be clean, dust free and strict filtration of air in the baking room. 2. The baking temperature can meet the technical requirements of different coatings. 3. The exhaust device must be set up in the paint baking room, so that the solvents and decomposition substances from the coating can not exceed a certain concentration during drying, so as to prevent the drying speed, quality and even explosion. 4. The wet paint film of solvent coating should be set aside for a certain time before drying, so that most of the solvents in the paint film can be volatilized and leveled, which can reduce the defects of "orange peel", "pinhole" and "blister".
3) the classification of the lacquer room. According to the different drying methods of the paint film, the baking paint room can be divided into two kinds of drying type and irradiation curing type. (1) drying type baking varnish room. Drying type baking paint room can be divided into natural convection, circulating fan convection and far infrared radiation 3. At present, the far-infrared radiating paint house is widely applied in the domestic maintenance enterprises. The far-infrared radiation baking room temperature range is generally 38-83 degrees. The automobile maintenance enterprises can choose the number and location of the infrared lamp tubes flexibly according to the baking range. The energy conversion form of far-infrared heating is mainly thermal radiation, so the possibility of dust adhesion to paint surface is greatly reduced compared with the heating cycle of heated air. The drying of paint surface by far infrared radiation not only shortened the drying time of paint film (shortened from one day to 30-50min), improved the operation efficiency, but also helped to improve the quality of painting. (2) irradiation cured paint room. This lacquer room has two kinds of light curing and electron beam curing, which are rarely used in the general repair and coating industry.
