The surface coating of auto parts coating equipment includes three basic processes: treatment of the surface of the object to be coated, coating process and drying before coating, as well as selecting suitable coatings, designing a reasonable coating system, determining good operating environment conditions, and carrying out Quality, process management and technical economy and other important links, the appearance quality of surface coating products not only reflects the protection and decoration performance of the product, but also an important factor that constitutes the value of the product.
Electrostatic coating is to form a high-voltage electrostatic field between the spray gun or spray disc and the workpiece to be coated. Generally, the workpiece is grounded as the anode, and the spray gun mouth is negative high voltage. Ionization, when the paint particles are charged through the muzzle and become dotted particles, when they pass through the corona discharge area, they are further combined with the ionized air to be charged again. The coated workpiece with opposite polarity moves and is deposited on the surface of the workpiece to form a uniform layer.
The spraying machine is a special coating equipment using spraying technology. The principle of the spraying machine is to control the airflow to instantly push the air distribution reversing device to reverse direction, so that the piston of the air motor can reciprocate stably and continuously. After the spraying machine enters the compressed air, the piston When it moves to the upper or lower end of the cylinder, the upper pilot valve or the lower pilot valve is actuated, and the air flow is controlled to instantly push the air distribution reversing device to change direction, so that the piston of the air motor can reciprocate stably and continuously.
