Titanium Electrodes For Water Electrolysis Machines

1. Purchase the GR1 titanium substrate to ensure that the surface of the plate is smooth and flat, without deep scratches and defects.

2. Machining the purchased titanium substrate and processing it to the size required by the customer.

3. Annealing and leveling the titanium substrate at a temperature of >500 °C. (To eliminate stress and ensure flatness.)

4. When the annealing leveling treatment, a dense titanium oxide layer is formed on the surface of the titanium substrate, and it is polished by mechanical or artificial means, and the surface thereof is made of titanium metallic luster.

5. The titanium substrate is subjected to pickling etching with 10% strength oxalic acid, and is subjected to a micro-boiling state for several hours to etch the surface oxide layer into a titanium hydride surface.

6. Qualitative and quantitative configuration of the precious metal solution according to the anode environment applied by the customer.

7. Detecting that the pickled titanium substrate is qualified, that is, the surface layer is gray uniform matte structure, and then manually coating and arranging, sintering at a set temperature, sintering naturally, cooling, and cooling to normal temperature for a second coating Resume, and so on, until the configuration solution is finished after 17~20 times.

8. After the sintering of the above processed parts is completed, the life test will be carried out with the test piece of the furnace, and the qualified package will be shipped.

Electrolysis electrodes are an important part of the electrolysis cell, and their selection has a crucial impact on the efficiency and quality of the electrolysis process. The correct selection of electrolysis electrodes can not only improve the efficiency of the electrolysis process, but also extend the service life of the electrolysis electrodes and reduce the cost of electrolysis. This article will introduce how to choose a suitable electrolysis electrode from three aspects: material, shape and size.
1.Material selection
The material of electrolysis electrode is an important factor affecting the efficiency and quality of electrolysis. Generally speaking, the materials of electrolysis electrodes should have high conductivity, corrosion resistance and wear resistance. Commonly used electrolysis electrode materials include steel, iron, copper, aluminum, titanium, platinum, gold, silver, etc. When selecting materials, the selection should be based on the properties of the electrolyte and the requirements of the electrolysis process. For example, for electrolytes containing ammonia ions, materials resistant to ammonia corrosion, such as titanium or platinum, should be selected; for high-temperature electrolytes, materials resistant to high temperatures, such as steel or aluminum, should be selected.
2. Shape selection
The shape of the electrolysis electrode is also an important factor affecting the efficiency and quality of electrolysis. Generally speaking, the shape of the electrolytic electrode should conform to the flow potential state and electric field distribution of the electrolyte. Common electrolysis electrode shapes are rod-shaped, plate-shaped, mesh-shaped, spherical, etc. When selecting the shape, the flow state of the electrolyte, such as the flow rate, flow direction and flow rate of the electrolyte, as well as the laws of electric field distribution, such as electric field strength and electric field direction, should be taken into consideration. For example, when the electrolyte flow rate is slow, electrolysis electrodes with large surface areas and regular shapes, such as mesh or plate-shaped electrolysis electrodes, should be selected to increase electrolysis efficiency.
3. Size selection
The size of the electrolysis electrode is also an important factor affecting the efficiency and quality of electrolysis. Generally speaking, the size of the electrolysis electrode should be selected according to the flow state of the electrolyte and the electric field distribution law. Common electrolysis electrode dimensions include diameter, length, width, thickness, etc. When selecting the size, the flow state of the electrolyte and the laws of electric field distribution should be taken into consideration, such as the flow rate, flow direction and flow rate of the electrolyte, as well as the electric field strength and electric field direction. For example, if the electrolyte flow rate is fast, an electrolysis electrode with a smaller diameter and a longer length should be selected to increase the electrolysis efficiency.
The selection of electrolysis electrodes is an important factor affecting the efficiency and quality of electrolysis. Correct selection of the material, shape and size of electrolysis electrodes can improve the efficiency and quality of the electrolysis process, reduce electrolysis costs and extend the service life of electrolysis electrodes. Therefore, when performing the electrolysis process, appropriate electrolysis electrodes should be selected based on the properties of the electrolyte and the requirements of the electrolysis process, taking into account factors such as material, shape, and size.
