Device for electrophoretic coating by electrodeposition coating device electrophoresis tank, stirring means, paint filter means, temperature control means, coating management apparatus, a DC power supply device, after washing electrophoretic coating means, ultrafiltration means, the baking means, spare tank and other components. The size and shape of the electrophoresis tank tank body to be determined according to the workpiece size, shape and construction technology. To ensure a certain distance between the electrodes under the conditions should be designed to be smaller as possible. Tank with filtration devices and thermostats to ensure a certain temperature liquid paint and remove impurities in the circulating liquid paint and bubbles. Fluid mixing device can maintain a uniform paint job, the use of circulating pump, circulating liquid paint 4 to 6 times per hour in general, when the circulation pump into operation, the tank liquid paint surface should be uniform flip. Effect paint management device to supplement adjust paint component, control PH value of the bath, a neutralizing agent and a separator electrode was removed by ultrafiltration unit exclude low molecular weight components and so on. Electrophoresis power supply options, generally use DC power supply. Rectifier device can be silicon rectifier or SCR. Current size and nature of the coatings, temperature, work area, power mode and so on, usually 30 ~ 50A / m2. Washing device for washing before and after the electrophoretic coating workpieces, generally with deionized water, subject to the compression device, commonly used in a rinse nozzle with a spirochete. Baking means for promoting the electrophoretic coating dry film, may be resistance furnace, electric induction furnace and infrared baking equipment. Oven design should preheat, heating and hot three-stage coating equipment electrophoresis coating should be developed according to the situation of species and the workpiece. Electrostatic painting is among gun or spray disc and the workpiece to be coated to form a high-voltage electrostatic field painting equipment, general grounding of the workpiece is the anode, the gun port is negative pressure, when the electric field intensity E0 is high enough, the muzzle of the air is near corona discharge, the air ionization occurs when electrically charged paint particles through the muzzle, become charged particles Sino painting equipment, in the corona discharge region, further integration and re-charged and ionized air, and the role of sub-ah high voltage electrostatic field of opposite polarity is applied to the workpiece movement, deposited on the surface, to form a uniform layer. When the electric field strength continues to increase, exceeding the limit Emax, fully ionized air layer between the muzzle and the workpiece to form a spark discharge and breakdown, then the risk of fires is easy, therefore, when the electrostatic coating operation, the electric field strength E E0 bridge should be selected in painting equipment, painting equipment, painting equipment provided by Sino Sino Painting Equipment Co. Qu. Linqu Sino Painting Equipment Co. (www.wfjn.com) (www.wfjn.com) (www.wftcsw.com) strong, credible, Shandong Weifang industrial automation control systems and equipment industry has accumulated a large number of loyal customers.
