Product Description

PbO2 coated titanium anode introduction:

Lead Dioxide (PbO2) coated Titanium (Ti) electrode plate is commonly used as an anode for electrodeposition processes of metals like copper, nickel, cobalt, and zinc. The combination of PbO2 and Ti makes for a highly corrosion-resistant and durable electrode that can withstand the harsh chemical environments of electroplating.

The use of PbO2 as a coating material for the Ti electrode plate provides several benefits. PbO2 is an excellent conductor of electricity, which allows for efficient transfer of electrons during the electroplating process. Additionally, PbO2 is highly resistant to corrosion, which helps to extend the lifespan of the electrode and reduce the need for frequent replacement.

Gr2 is the grade designation for commercially pure Titanium (CP Ti), which is commonly used in industrial applications due to its excellent corrosion resistance and biocompatibility. Using a CP Ti substrate as the base for the PbO2 coating provides a durable and reliable electrode for use in electroplating processes.

Product Advantages

Comparison of PbO2 coated titanium anode and traditional lead anode:
A. No pollution to the electrolyte, no complicated lead removal system expenses.
B. The external dimensions are fixed, and the anode will not deform due to self-dissolution, which will affect the appearance of the cathode product.
C. Since the titanium matrix is ​​not consumed during the electrolysis process, the titanium matrix can be recoated repeatedly
D. High current efficiency. At present, the current efficiency of the titanium anode produced by our company can reach 93-95%, while the current efficiency of the traditional lead anode is only 89-91%.
E. The tank voltage is low. The voltage of the titanium-based lead dioxide anode tank produced by our company is 2%-3% lower than that of the lead anode tank, and the power saving effect is very obvious.
F. The cathode product is of high quality. Because the solution does not contain lead, lead pollution is eliminated.
G. It can work with high current. The lead anode will quickly dissolve under high current. The titanium-based lead dioxide anode can withstand currents above 500A/m2, which is suitable for short-term and large-scale production requirements.
H. Reduce labor intensity and improve working environment. Lead anodes have the disadvantages of heavy weight, soft material, thinning during production, and easy deformation. As a result, the cathode nickel plates are also easy to deform. Workers often need flat plates during production, which is labor-intensive. At the same time, because lead is a heavy metal, it is highly toxic, affects the human nervous system and seriously pollutes the environment. At the same time, barium carbonate used for lead removal is also highly toxic.
In general, titanium-based lead dioxide anode saves 8% of energy consumption than lead anode electrowinning activity; higher price of high-quality cathode products. The combined benefits of multiple advantages will be very impressive.

Lead Dioxide Coated Titanium Electrode Plate PbO2 Gr2 Anode electrodeposition of copper, nickel, cobalt and zinc Application Case

Lead Dioxide coated titanium electrode plates (PbO2/Ti) are commonly used as anode materials for various electrochemical processes, including electrodeposition of metals such as copper, nickel, cobalt, and zinc. The use of PbO2/Ti anodes has several advantages, including high stability, corrosion resistance, and high current efficiency.

In the case of electrodeposition of copper, nickel, cobalt, and zinc, PbO2/Ti anodes are preferred due to their high oxygen evolution potential and low overpotential for metal deposition. This results in higher current efficiency and reduced energy consumption during the electroplating process. Additionally, PbO2/Ti anodes have a longer lifespan compared to other anode materials, leading to reduced maintenance costs.

The process of electrodeposition involves the reduction of metal ions from a solution onto a substrate surface under the influence of an electric field. During this process, the anode material is oxidized, leading to the formation of oxygen gas. PbO2/Ti anodes have a high oxygen evolution potential, which reduces the formation of hydrogen gas and other undesirable side reactions. This results in a cleaner and more efficient electroplating process.

Overall, PbO2/Ti anodes are a reliable and cost-effective solution for electrodeposition of metals such as copper, nickel, cobalt, and zinc. Their high stability, corrosion resistance, and high current efficiency make them an ideal choice for a wide range of electrochemical applications.
