The conventional electrophoresis process comprises the steps of suspending the electronic product in an electrophoresis liquid, electrifying for a period of time, electroplating a layer of electrophoresis paint on the outer surface of the electronic product with a narrow gap, cleaning the electronic product in a cleaning water tank after electrophoresis to remove the electrophoresis liquid attached to the outer surface, putting the cleaned electronic product in an oven, and drying the moisture on the surface of the electronic product through the oven, thereby finally obtaining the required electronic product with the narrow gap. However, the width of the gap is very small, the electrophoretic liquid remaining in the gap is difficult to be washed away by clean water, and the electrophoretic liquid cannot be completely dried during drying, so that when the electronic product is transported to a customer, the electrophoretic liquid remaining in the gap is poured out when the electronic product is used by the customer, and the electrophoretic liquid is very dirty, which undoubtedly causes great inconvenience to the customer, and the customer cannot use the electronic product at the same time, so that the subsequent process of cleaning the electronic product needs to be returned.
In addition, the electrophoretic liquid comprises epoxy resin and color paste, and the volume ratio of the epoxy resin to the color paste is 4: the electrophoretic paint layer electrophoresed by the electrophoretic liquid has a bright surface and very high glossiness, namely, the local area of the surface has reflection (such as the surface of a mouse and the surface of a ball pen shell), and when a human eye sees the electrophoretic paint layer, the human eye feels uncomfortable. Therefore, an electrophoresis process capable of improving the appearance quality of the electrophoretic paint layer and avoiding the residual electrophoretic liquid in the gap is needed.
