Manufacturing technology and flow of titanium anode
1. Welding
According to customer drawings, some products need to be welded after blanking and punching. The welding of titanium materials mainly adopts the method of argon arc welding, and only the same materials can be welded together. Plate, tube welding is fixed by spot welding, after welding, and for the net can only be spot welding.
2. Sand blasting
A treatment process that is sprayed onto the surface of the titanium matrix by means of compressed air power through the sand blasting machine. The sand is sprayed into the matrix for impact grinding, and the impurities, impurities and oxide layer on the surface are removed. At the same time, the sand blasting machine coarses the surface of the titanium matrix, improves the effective contact area of the titanium surface, and enhances the adhesion between the coating and the surface.
The main points of sandblasting, spraying pitting point, hemp surface should be uniform, can not leak out.
3. Annealing
Annealing is a metal heat treatment process in which the metal is slowly heated to a certain temperature, maintained for a sufficient time, and then cooled at a suitable rate.
When discharging, some materials themselves are bent or deformed. We can make simple correction through some methods and tools, so as not to excessively affect the following work. However, after the local high temperature of welding and the pressure of sandblasting, the deformation of the titanium substrate will be obvious.
Place the board (mesh) on a very thick sheet of steel with flat, aligned edges. Ruthenium Anode reminds you to place a second sheet of the same steel plate over the plate (mesh) and diagonal screws. Make the next two steel plates sufficiently squeeze the middle plate (net). After that, it is sent into the furnace with a temperature of about 500 for heating and shaping. After reaching a certain time, it is kept warm for 2 hours.
4. Brush
The precious metal liquid, with a brush and brush coated on the matrix, into the drying furnace for drying, so that the liquid quickly combined with the matrix, but also to prevent the liquid down to the matrix left traces. The first 5 brushes, liquid can be applied more, can fill the matrix surface. The back needs to brush less liquid, so that the liquid brush is painted more evenly, but also can cover the front brush flower, so that the coating is beautiful. It is required to wear a mask when brushing, and the environment is ventilated and dust-free, especially no water. To ensure the purity of the liquid, the appearance of the board.
5. Bake
Plate after drying, into the furnace has reached a certain temperature for a certain time to pull out, so that its natural cooling, oxidation. And then we move on to the next program.
Repeat procedures: brush coating, drying, heating and insulation, cooling.
Brushing procedure about 20~40 times
6. Cut the material
The process of removing a material of a certain shape, quantity, or quality from a whole or batch of materials after determining the shape, quantity, or quality of the material needed to make a device or product.
Then select good material, according to the drawings, and customer requirements to make a certain shape, quantity. To make a mark or punch a hole. Whether to polish, which should be strictly according to the requirements of the drawings to operate. Reasonable planning of processing technology to reduce loss. Cut the material with precision.
7. Liquid allocation
Configure precious metal solution according to customer requirement. Usually the mixture is prepared the day before the brush is scheduled, because the prepared liquid has to be dried for a period of time before it can be used. While drying, you need to stir constantly to prevent the liquid from settling.
8. Pickling
Ruthenium anode company for you to explain the pickling process of the acid lotion is generally a mixture of various acids, mainly sulfuric acid, nitric acid and hydrofluoric acid, these mixed acid corrosion is very strong, at the same time has a strong oxidation, high corrosion medium temperature, which puts forward high requirements for corrosion resistance of anticorrosive materials. According to a certain proportion of oxalic acid into the boiling water, the base material into the boiling pot for boiling, soaking. Oxalic acid can not only effectively remove the blue oxide skin on the substrate during annealing, but also make the surface of the substrate rougher and remove surface impurities through corrosion.
During pickling, attention should be paid to the change of the titanium matrix to prevent the formation of titanium oxalate on the surface of the matrix.
