The equipment of the home appliance coating equipment is composed of an electrophoresis tank, a stirring device, a paint filter device, a temperature adjustment device, a paint management device, a DC power supply device, a washing device after electrophoretic coating, an ultrafiltration device, a baking device, a spare tank, etc. .

The size and shape of the electrophoresis tank should be determined according to the size, shape and construction process of the workpiece. Under the condition of ensuring a certain distance between poles, the design should be as small as possible. The tank is equipped with a filtering device and a temperature adjustment device to ensure a certain temperature of the paint solution and remove impurities and bubbles in the circulating paint solution. The stirring device can keep the working paint uniform. Circulating pumps are often used. The circulation of the paint is generally 4-6 times per hour. When the circulating pump is activated, the surface of the paint in the tank should be evenly turned. The role of the paint management device is to supplement and adjust the composition of the paint, control the pH value of the bath, use the membrane electrode to remove the neutralizer and use the ultrafiltration device to remove low molecular weight components. The choice of electrophoresis power supply generally adopts DC power supply. The rectification equipment can use silicon rectifiers or silicon controlled rectifiers. The size of the current is related to the nature of the coating, temperature, working area, and power supply mode, and it is generally 30-50A/m2. The water washing device is used to wash the workpiece before and after electrophoresis coating. Generally, deionized water is used, but pressurized equipment is required. The most commonly used is a washing nozzle with a spiral body. The baking device is used to promote the drying and film formation of the electrophoretic paint, and can use resistance furnace, induction electric furnace and infrared baking equipment. The design of the drying room should have three stages of preheating, heating and post-heating, which should be formulated according to the type of coating and the condition of the workpiece.
