The working principle of this electroplating copper refrigerator steel pipe production line is to use alkali rectification cleaning to remove grease from the surface of the steel pipe (3-6.35mm annealed pipe and 8mm non annealed pipe) for the disc-shaped refrigerator steel pipe. The acid activates the surface of the steel pipe, and then a layer of nickel is plated on the surface of the steel pipe to make a bottom layer. Then, it enters a copper containing electrolytic solution, and a DC power supply is connected to the anode (copper plate) and cathode (steel pipe) to exchange anions and cations, Thus, a uniform copper layer, namely a copper plating layer, is attached to the surface of the steel pipe.
Loading → Calibration → Alkali washing → Water cleaning → Acid activation → Water cleaning → Nickel plating → Water cleaning → Copper electroplating → Water cleaning → Passivation and sealing → Drying → Traction → Reeling → Packaging
