1. Application areas: galvanizing, precious metal plating (including gold plating, silver plating, palladium plating, etc.); hard chromium plating; nickel plating; tin plating (steel plated tin).
2. Coating Type: Titanium-based Ruthenium Iridium
3. Compared with conventional lead anodes for electroplating
1) Low tank voltage and low energy consumption
2) The rate of electrode loss is small and the size is stable
3) The electrode has good corrosion resistance, insolubility and does not pollute the bath, making the performance of the coating more reliable.
4) Titanium anode adopts new materials and structure, which greatly reduces its weight and facilitates daily operation.
5) Long service life, and the substrate can be reused, saving costs
6) The oxygen evolution overpotential is about 0.5V lower than that of the lead alloy insoluble anode, which reduces the cell voltage and reduces energy consumption.
4. Product use background and introduction:
In the field of electroplating, the required plating metal is dissolved in the electrolyte, the metal substrate to be plated is used as the negative electrode, and the anode is used as the positive electrode, which forms a complete current transmission cycle. The chemical reaction that occurs simultaneously with the plating in the plating bath is the precipitation of oxygen on the anode surface.
Compared with non-inert anodes such as graphite, titanium anodes have the advantage that they can maintain a stable distance between the positive electrode and the negative electrode (distance between the electrodes) during the service life. Graphite anodes will gradually dissolve during use, leading to an increase in the distance between the electrodes, while inert titanium anodes can ensure stable voltage and product quality. Due to the catalyst properties of platinum group elements, the exchange current density value on the electrode surface is large, and the over-potential for oxygen precipitation is low, and a special process is used to make a fine-structured oxide film on the titanium surface. The active surface area is especially suitable for high-speed and high-current density electroplating production.
In addition to titanium anodes and graphite, lead anodes can also be used in this field. However, when the lead anode is dissolved, its reactants have a negative impact on the environment. Such problems as titanium anodes can be avoided. The operating voltage of the oxygen-evolving titanium anode is low, which can also save energy.
Another advantage of using a titanium anode is that the titanium matrix can be reused. When the titanium anode coating reaches its end of life
Anodized aluminum foil is a material commonly used in the lithographic industry. The working principle is the same as the electroplating process. A thin layer of metal covers the surface of the base metal. By placing aluminum in the anode state, the surface of aluminum is oxidized. After the anodization (oxidation) process of aluminum, the surface of aluminum can better adhere to the photosensitive coatings required in the lithographic printing industry.
In the electroplated metal industry, anodes are used to electroplate a variety of substrates, from small-scale production of jewellery to continuous large-scale production of electroplated steel plates. The company’s anode products have helped to achieve a variety of electroplating substrates. At the same time, its diversity has also been reflected in the company’s anode products.
