The electroplating process is a process of depositing metal ions in the solution on the surface of a cathode plated part by a loop consisting of an electrolyte, a cathode and an anode under the action of a direct current electric field. Therefore, during the electroplating treatment, the solution state in the inner cavity of the workpiece and the electric field distribution on the surface of the workpiece are critical to the quality of the coating by means of the transmission of the cathode conducting device to the workpiece. When processing some large-scale workpieces with inner cavities, for example, when processing an oil tank, because the electrogalvanizing process can produce gas, if the oil tank opening faces downwards, the gas can be stored in the inner cavity, so that the surface to be galvanized inside the oil tank is separated from the solution, and the oil tank opening cannot be galvanized, therefore, the oil tank opening needs to be arranged upwards during galvanizing.
The general electrogalvanizing process comprises the following steps: oil removal, washing, rust removal, washing, galvanization, washing, light emission, washing, passivation, washing, drying and aging treatment (80-90 ℃ in a drying oven). Wherein, in order to ensure the galvanized surface quality, the light emission (acid mixing, corrosion zinc layer light emission, generally 10-15 seconds according to the process) must be carried out, the light emission time must be controlled, otherwise, the zinc layer can be removed.
However, when the oil tank is upward, after the oil tank enters the light emitting process after being galvanized, the light emitting liquid can only flow out from the bottom of the oil tank as the through hole of the liquid discharge hole, but because the liquid discharge flow of the liquid discharge hole is limited, the time between the time when the light emitting liquid completely submerges into the oil tank from the oil tank and the time when the light emitting liquid completely flows out from the inner cavity of the oil tank still greatly exceeds the time required by the light emitting process of the oil tank, and the bottom leakage of the coating at the bottom of.
