Supercapacitor aluminum shell surface treatment process
As a kind of metal product, aluminum products are still relatively common in today's production or production. Because aluminum has such very good performance characteristics, aluminum metal has a very wide range of applications. The supercapacitor aluminum shell can be seen as an aluminum product from the name. So, do you have any relevant knowledge about the super capacitor aluminum shell? In the production of super capacitor passengers, the surface treatment process must be carried out. What is the surface treatment process of the supercapacitor aluminum shell?
1. Degreasing: The purpose of caustic washing is mainly to remove the oil stain on the surface of the aluminum alloy. The commonly used alkali washing solution consists of Na2CO3, Na3PO4, Na2SiO3 and additives. It is mainly used for dipping and spraying, and can also be used for electrolytic cleaning and ultrasonic cleaning.
2. Removal of oxide film: The oxide film naturally formed on the surface of aluminum is a non-uniform discontinuous film, which must be completely removed before coating. For the die casting, nitric acid can be used to remove the surface oxide film.
3. Chemical conversion: The purpose of the conversion treatment is to form a dense and uniform continuous film on the surface of the aluminum alloy. The effect of this process is equivalent to the phosphating process in the surface treatment of steel parts, but the solution is different. The conversion film of aluminum and aluminum alloy is based on chromic acid/hydrochloric acid, phosphoric acid/hydrochloric acid and hydrofluoric acid, and the quality of the conversion film is usually After the formation of the conversion film of 215 g/m2, it must be washed with water and then dried with hot air to enhance the hardness of the film layer.
