1. Material selection is the first step of the processing technology, and it is also a more important part. The materials of the corresponding grades and specifications should be selected according to the requirements of the customer's drawings, and the quality of the selected materials will directly affect the quality and use of the anode.
2. Pay attention to the selection of materials. Titanium mesh: no broken wires or broken roots can occur. Titanium plate: The plate type is better to choose a flat plate, and pay attention to the surface without peeling, delamination, cracks, and other defects. Choose the right material to reduce loss.
1. After determining the shape, quantity or quality of materials required to make a certain equipment or product, from the entire or entire batch of materials
2. The operating process of removing materials of a certain shape, quantity or quality.
3. After selecting the material, make a certain shape and quantity according to the drawings and customer requirements. Draw lines, dots to make marks, and punch holes. Whether it needs to be polished, the operation must be strictly in accordance with the requirements of the drawings. Reasonably plan the processing technology to reduce losses.
4. The blanking must have precision.
After cutting and drilling, some products need to be welded. The welding of titanium materials mainly adopts argon arc welding, and only the same materials can be welded together. The plate and tube welding method is to first use spot welding to fix, and then to fully weld, but for the net, only electric welding can be performed.
1. A treatment process in which the sandblasting machine uses compressed air power to spray onto the surface of the titanium substrate. Sand is sprayed to the substrate for impact grinding to remove impurities, noise and oxide layer on the surface. At the same time, the sandblasting machine roughens the surface of the titanium substrate, increases the effective contact area of the titanium surface, and enhances the adhesion of the coating to the surface.
2. The main points of sandblasting, the pitting and pitting surface should be even, and the spraying should not be missed.
1. The pickling liquid in the pickling process is generally a mixture of various acids, mainly sulfuric acid, nitric acid, and hydrofluoric acid. These mixed acids are highly corrosive, and have strong oxidizing properties and high corrosive media. Temperature, which puts forward high requirements on the corrosion resistance of anti-corrosion materials. Pour oxalic acid into the boiling water according to a certain ratio, and put the substrate into the boiling pot for boiling and soaking.
2. Oxalic acid not only can effectively remove the blue oxide scale on the substrate during annealing, but also can make the surface of the substrate rougher and remove surface impurities through corrosion.
3. When pickling, always pay attention to the changes of the titanium matrix to prevent it from becoming titanium oxalate.
1. Annealing is a metal heat treatment process that slowly heats the metal to a certain temperature, keeps it for a sufficient time, and then cools it at an appropriate speed.
2. When cutting the material, some materials are bent or deformed. We can make simple corrections through some methods and tools, so that it will not affect the next work excessively. However, after the local high temperature of welding and the air pressure of sandblasting, the deformation of the titanium substrate will be obvious.
3. Annealing can restore the deformed board (net) to a flat state.
4. Place the board (net) on a very thick steel plate. It is required to lay it flat and align the corners. Put another piece of the same steel plate on the board (net) and screw on the diagonal corners. Make the next two steel plates fully squeeze the middle plate (net). After that, it is sent to a furnace with a temperature of about 500 for heating and shaping. After a certain period of time is reached, the temperature is maintained for 2 hours.
Configure the precious metal solution according to the actual needs of customers. Usually, the liquid preparation is prepared the day before the brushing is planned, because the prepared liquid can only be used after a period of drying. While drying, it is necessary to keep stirring to prevent the liquid from settling.
1. Apply the prepared precious metal liquid on the substrate with a brush, and then enter the drying oven for drying, so that the liquid is quickly combined with the substrate, and it also prevents the traces left by the liquid when it flows down the substrate. After drying, heat it into the furnace that has reached a certain temperature and pull it out for a certain period of time to allow it to cool and oxidize naturally. Brush again. Repeat: brushing, drying, heating and keeping warm, and cooling.
2. In the first 5 times of brushing, the liquid can be applied more and the surface of the substrate can be filled. You need to brush less liquid in the back, so that the liquid can be applied more evenly, and at the same time, it can also cover the place where the flowers are painted in the front to make the coating beautiful. It is required to wear a mask when brushing, the environment, ventilation, dust-free, especially not see water. To ensure the purity of the liquid and the beautiful surface of the board.
The coating acceptance is divided into two categories: life-enhanced inspection and finished product acceptance. The enhanced life test is mainly based on the country's enhanced life test standard 12176. Finished product acceptance is mainly to visually observe the uniformity of the coating, and there is no pattern as a whole.
