Process of Tubular Titanium Anode
Shearing
In the shearing stage, the titanium substrate is precisely cut without forming chips. This process ensures that the substrate pieces have the desired dimensions and shapes required for the anode.
Welding
Once the substrate pieces are cut, they are joined together using argon arc welding. This welding technique creates a strong and secure connection between the substrate pieces, forming the anode skeleton. The welding process is crucial in ensuring the structural integrity of the anode.
Sandblasting
After welding, the anode surface undergoes sandblasting. This process involves propelling abrasive particles onto the surface to remove any oxidation and contaminants. Sandblasting also increases the surface roughness, providing better adhesion for the subsequent coating.
Annealing
The anode skeleton undergoes an annealing process, which involves heat treatment. Annealing helps improve the metal properties of the titanium substrate, including strength, ductility, and resistance to defects. This step ensures that the anode has the necessary mechanical properties to withstand operational demands.
Acid Pickling
To prepare the substrate for the coating process, it undergoes acid pickling. The titanium substrate is immersed in an oxalic acid solution, which effectively removes stains, rust, and other impurities from the surface. Acid pickling ensures a clean and uniform substrate, facilitating proper coating adhesion.
Coating Solution Preparation
The next step involves the preparation of a suitable coating solution. The composition of the coating solution depends on the desired properties and application requirements. It often includes precious metals such as ruthenium, iridium, platinum, or a combination of mixed metal oxides. The coating solution is carefully formulated to achieve the desired coating characteristics.
Coating
The prepared coating solution is applied to the surface of the titanium anode. Various techniques can be employed for coating, including brush coating, dipping, or spraying. The goal is to achieve an even and uniform coating layer on the anode surface. After application, the anode is dried in a furnace to remove any excess moisture.
Sintering
The coated anode undergoes a sintering process. During sintering, the anode is subjected to a controlled heating process, typically in a furnace. This step strengthens and solidifies the coating, enhancing its adhesion to the titanium substrate. Sintering also optimizes the properties of the coating, ensuring long-term stability and high performance.
Precautions for Tubular Titanium Anode Use
The titanium electrode has a black surface of ruthenium dioxide and iridium dioxide or iridium dioxide and tantalum pentoxide after oxidation and sintering. The black side corresponds to the cathode. The uncoated surface is a blue or gray titanium dioxide surface. The surface does not have electrode properties.
Once the titanium electrode substrate is pickled, all subsequent production and processing procedures and use must be carried out strictly and carefully. When embezzling, installing and disassembling, wear clean gloves to jam the ends or edges of the anode. It is best to touch the anode without coating. part. Any scratches on the coating surface are strictly prohibited.
Avoid the use of reversed poles. Once the precious metal oxide coating is used as a cathode, the surface will produce a reduction reaction to transform into a metal element, and it will not be able to effectively combine with the titanium base. Cause the coating to fall off. If the pure titanium material is used as an anode, the intense oxidation reaction on the surface will make the titanium material especially easy to be dissolved.
Add a filter device before the electrolyte enters the electrolytic cell. It must not contain metal ions with a diameter greater than 0.1mm to prevent excessive accumulation and cause short circuit between the anode and the anode.
