The insoluble anode for electroplating is coated with a noble metal oxide coating having high electrochemical catalytic properties on a titanium substrate (mesh, plate, ribbon, tube, etc.) containing a highly stable valve metal oxide. The new insoluble titanium anode has high electrochemical catalytic energy, and the oxygen evolution overpotential is about 0.5 V lower than the lead alloy insoluble anode. The energy saving is remarkable, the stability is high, the plating solution is not polluted, the weight is light, and the replacement is easy.
The electroplating insoluble titanium anode comprises a fixing portion, a precipitation portion and a surrounding portion, thereby effectively increasing the insoluble anode area by the surrounding portion thereof, thereby increasing the load capacity of the anode and increasing the effective solubility of the anode area without causing the concentration of the plating solution The rapid increase allows the supply to be effectively deposited on the opposite side of the workpiece, increasing the effective precipitation of the supply, actually increasing the plating capacity, and not causing the supply to be jammed to facilitate the replenishment of the supply, thereby improving the overall use.
The oxygen evolution overpotential of the insoluble titanium anode for electroplating is also lower than that of the platinized insoluble anode. It is widely used as an anode or an auxiliary anode in various electroplating, and can replace the conventional lead-based alloy anode. Under the same conditions, the groove can be lowered. Voltage, saving power consumption; titanium anode for electroplating has good stability (chemical, electrochemical) in the electroplating process, and has a long service life. This anode is widely used in the electroplated non-ferrous metal industry such as nickel plating, chrome plating, galvanizing, and copper plating.
Insoluble titanium anode for electroplating is composed of sintered multi-layer special mixed precious metal oxide on titanium substrate. It is resistant to high current density impact and resistant to strong acid corrosion. It can be stably operated for a long time at a current density of 5000A/m2. The anode can be made into various shapes. , fully meet the requirements of users; it can be applied to galvanizing, copper plating, nickel plating, chrome plating, high corrosion resistant zinc alloy plating, imitation gold plating, nickel-zinc alloy, nickel-tin alloy, electronic plating, tin plating, gold plating , methanesulfonic acid tin-lead alloy and other occasions.
