Device electrophoretic coating by electrodeposition coating equipment electrophoresis tank, stirring means, paint filter means, temperature regulation means, paint management apparatus, a DC power supply device, after washing electrophoretic coating means, ultrafiltration means, the baking means, spare tank and other components. Electrophoresis tank size and shape of the tank to be determined according to the workpiece size, shape and construction technology. In ensuring a certain distance between the electrodes coating line design conditions, should be designed to be smaller as possible. Tank with filtration means and temperature regulating means, in order to ensure a certain temperature and liquid paint circulating liquid paint removing impurities and bubbles. Stirring device can work to maintain uniform liquid paint, the use of a circulating pump, circulating liquid paint is generally 4 to 6 times per hour, when the circulation pump is running, the tank fluid level should be uniform flip paint. Effect paint management apparatus is added to adjust the paint component, controlling the PH value of the bath, the electrode separator to remove the neutralizing agent and the use of an ultrafiltration apparatus to exclude low molecular weight components and the like. Electrophoresis power supply options, generally use DC power supply. Rectifier equipment can be silicon rectifier or SCR. Current size and nature of the coating, temperature, work area, power mode and so on, usually 30 ~ 50A / m2. Washing means for flushing the workpiece before and after the electrophoretic coating, generally with deionized water, subject to the compression device, commonly with a spirochete leaching nozzle. Baking equipment used to facilitate electrophoretic coating dry film, may be resistance furnace, induction furnace and electric infrared baking equipment. Oven design should preheating, heating and hot three sections, should be developed according to the situation paint varieties and the workpiece. (6) ultrafiltration system to control the concentration of impurity ions into the workpiece, to ensure coating quality. In running this system should be noted that once the system is running should run continuously, non-intermittent operation coating line, to prevent dry ultrafiltration membrane. After dry resin and pigment in the ultrafiltration membrane attached powder coating line, can not be thoroughly cleaned, it will seriously affect the ultrafiltration membrane permeability rate and service life. Ultrafiltration membrane water rate increases with time running downward trend, from 30 to 40 days of continuous work should be cleaned once in order to ensure the required ultrafiltration ultrafiltration dip and rinse water. (7) electrophoretic coating method is suitable for a large number of assembly line production process. Electrophoresis bath update cycle should be three months or less. With an annual output of 300,000 copies of the production line, for example rims electrophoretic coating line equipment, scientific management of the bath is extremely important for the various parameters of the bath on a regular basis to detect and according to test results to adjust and replace the bath . Generally follows the frequency measurement of bath parameters: electrophoretic fluid, cleaning fluid ultrafiltrate and ultrafiltration, yin (male) very liquid, wash cycle, deionized cleaning fluid PH, solid content and conductivity once a day; Yen Kibbee, organic solvent content, laboratory tests twice a week for a small tank.
