Titanium electrodes are widely used. Our usual applications include water treatment, wastewater treatment, sewage treatment and other industries. Many of our partners are also wastewater treatment plants and sewage treatment plants.

Today I mainly introduce the production process of titanium electrodes.

  1. Cutting

Operation process of removing a certain shape, quantity or quality of materials from the whole or entire batch of materials after determining the shape, quantity or quality of materials required to make a certain equipment or product.
After selecting the materials, make a certain shape and quantity according to the drawings and customer requirements. Marking, marking, and punching. Whether it needs to be polished, which should be operated strictly according to the requirements of the drawings. Reasonably plan the processing technology to reduce losses. The cutting must have precision.

   2. Welding

After the steps of blanking, drilling, laser cutting, etc., it is necessary to weld afterwards. The welding of titanium materials mainly adopts the method of argon arc welding, and only the same materials can be welded together. The welding method of the board and the tube is to use spot welding to fix it first, and then the welding is full, but only the spot welding can be performed for the net. Titanium anodes and titanium meshes are common materials required by titanium anode customers.

   3. Sandblasting

After the welding is completed, we will treat the surface of the titanium material, which is mainly a process of spraying onto the surface of the titanium substrate by means of compressed air power through a sand blasting machine. Sand material is sprayed onto the substrate for impact grinding to remove impurities, noise and oxide layers on the surface. At the same time, the sand blasting machine roughens the surface of the titanium substrate and increases the effective contact area of ​​the titanium surface. The purpose of this is to strengthen the coating and The adhesion of the titanium surface.
The points that should be paid attention to when blasting are: The pitting and pitting of the spray should be uniform, and the spraying cannot be missed or sprayed repeatedly in some places.


   4. Annealing

Annealing is a metal heat treatment process that slowly heats the metal to a certain temperature for a sufficient time, and then cools at a suitable rate. Simply speaking, through annealing treatment, we can make the titanium material achieve the purpose of straightening.
When blanking, some materials themselves are bent or deformed, we can use some methods and tools to make simple corrections, so that it does not unduly affect the next work. However, after the local high temperature of welding and the air pressure of sandblasting, the deformation of the titanium substrate will be obvious.
Place the board (mesh) on a very thick steel plate, requiring it to be leveled and aligned with the corners. Ruthenium Anode Company reminds you to put another same steel plate on the board (net) and screw it diagonally. Make the next two steel plates fully squeeze the middle board (net). After that, it is fed into a furnace with a temperature of about 500 for heating and shape correction. After reaching a certain time, it is kept for 2 hours.


   5. Brushing

Apply the prepared precious metal liquid (Ru-Ir, Ir-Ta, or platinum coating and other precious metal coatings) on the titanium substrate with the same brush, and then put it into the drying furnace for drying to make the liquid fast The combination with the substrate also prevents the traces left by the liquid flowing down the substrate. During the first 5 brushings, the liquid can be overcoated and can fill the surface of the substrate. You need to apply less liquid behind to make the liquid more evenly applied. At the same time, it can cover the area where the front is brushed to make the coating beautiful. It is required to wear a mask when brushing, the environment, ventilation, dust-free, especially no water. To ensure the purity of the liquid, the appearance of the board.


   6, baking

Titanium anode plates (some titanium cathode plates need to be used for conducting, so they also need to be coated with precious metals), after drying, enter the furnace that has reached a certain temperature and keep it out for a certain period of time to let it naturally cool and oxidize. Then enter the next procedure.
Repeat the procedure: brushing, drying, heating and cooling, and cooling.
Brushing procedure about 20-22 times

The titanium anode is completed. Finally, shockproof materials are used for individual packaging to prevent scratches on the coating. Each titanium anode product must be individually packaged, and finally packed and transported in a standard export wooden box or carton.
