Pre-treatment equipment:

Pre-treatment equipment using full spray cleaning method, composed of 9-13 processes (depending on the situation can be selected). All the process tank wall, chamber wall, circulating pipes are made of stainless steel. According to different working conditions, the inner wall of the process tank is made of 316L stainless steel or 304 stainless steel. In order to prevent the string of liquid between the slot or spray interval of the workpiece drainage time of 0.5 to 1 minute (interval length 2m ~ 4m). Washing should be used countercurrent cleaning method. At the outlet of the pretreatment equipment, there shall be a drainage section and an automatic blowing device.

 

Water drying room:

Water drying room with a large amount of hot air convection heating, import and export gas seal device installed to achieve the purpose of saving energy. The use of ternary direct-fired gas stove, fan, hot stove and high temperature filter combination as a whole, the overall assembly area of small pollution to reduce the link.

 

Electrostatic Precipitation Room:

Spraying the electrostatic precipitator to the workpiece before blowing ionized air, remove the electrostatic adsorption of dust on the workpiece. Static fan inlet filter dust removal device, to be cleaned regularly. The electrostatic precipitator is provided with exhaust system, and the suction outlet is provided with a filtering device.

 

Powder room and spray booth:

Paint room air cleaning degree of 10,000, the illumination range 800lx-1000lx; spray room into the exhaust volume can be adjusted to ensure the positive pressure spray room and energy saving requirements. Dusting room illumination of not less than 300Lx. The temperature control is: 20 + 2 ℃ in winter, 26 + 2 ℃ in summer and 60 ℃ in the leveling chamber. The amount of dust in the air supplied to the powder chamber is less than 1.5 mg / m3, and the size of the dust particles is 3 m or less.

 

Paint drying oven and powder curing oven:

Paint drying oven and powder curing oven with bridge drying structure, with the prevention of hot air spill and insulation effect, in order to achieve the purpose of saving energy. Room wall panels should be equipped with good insulation measures, can not produce thermal bridge.

 

Application of mechanized conveyor systems:

Transportation equipment is usually used in suspension conveyor system and ground transportation system. Pre-treatment line with ordinary type of hanging conveyor. Transmission speed adjustment using frequency conversion, stepless speed regulation and manual operation with emergency stop button. Pre-treatment with oil pan across the board. Dusting room and spray booths and drying equipment using ground transportation system. Ground conveyor should be anti-mist and high temperature, the same transfer rate adjustment using frequency conversion method, should be stepless speed regulation, in the upper and lower parts and workers operating with emergency stop button. In the powder room and spray room with rotating device (positive, reverse function), to ensure the workpiece to achieve positive and negative spraying. Drying furnace track with telescopic function, can absorb the temperature caused by changes. Such as the use of wheels running parallel to the drying room, should be automatically reproduced by the robot to ensure safe and reliable reprint. 3.3 to determine the process plan, aluminum wheel coating line construction should be able to adapt to the needs of flexible mass production, a single coating line is usually the economic output conveyor speed of 7m / min is appropriate. Robot painting is the trend of painting, robot spraying should be used. So that coating production to save energy, paint, improve the quality of products and a spray pass rate to achieve the purpose of recovering investment as soon as possible. Must develop a new coating energy-saving equipment. Research and development of energy-saving spray-painted robot room, the application of air circulation to reduce the amount of air into the air, so that the solvent spray room to maintain the explosive concentration in the lower limit of the following can be. In the winter production spray booth can save a lot of heating energy consumption.

 

Methods and other parts of the vehicle spray similar, but there are certain prerequisites:

Due to its special use of "conditions", the weight of the vehicle driving, rain washing, acid-base material erosion, high-speed operation of the heat generated by the heat and the brake to pass ... ... are required to maintain its:

A, the length of the wheels (rims) to remove the "residual" paint or "coating" and fully dried or dried, and then the appropriate "spray" or "chrome" treatment. So it is not necessarily paint, look at the wheel material to determine the specific method of operation. In this case,

B, the wheel inside, that is, for the brake surface, more easily overlooked areas, the impurities such as adhesion of the asphalt, spots, oxide, etc. must be handled clean. To ensure that the hub inside and outside the "convergence" is just, up to "beautiful" and "lasting" effect.

C, the choice of "materials" to special materials, and ordinary "paint" requirements even higher. If it is "coating", is the same. Not only in the wheel material to withstand special "erosion" of the conditions, the same, "external" material must also be selected: temperature, acid and so on. In this case,

D, due to the "hub" shape of the special, point, line, surface must be handled in place, which requires a certain level of technology, "seemingly simple" process. Careful, seriously as the premise. In this case,

E, other aspects, such as the use of construction methods and the environment, and the general "spray" or "coating (chrome)" is no different.
