Electro galvanized steel sheet is a metal product in which the surface of steel sheet is covered with a layer of zinc by electrolysis. The product not only inherits the strength and toughness of steel plate, but also possesses excellent anti-corrosion properties due to the presence of zinc layer. Electro zinc plating is a method of depositing a layer of metallic zinc on the surface of steel plates by means of electrolysis. This process mainly includes three steps: pre-treatment, zinc plating and post-treatment. The pretreatment stage is mainly to clean, degrease and descale the steel plate to ensure that the surface of the steel plate is clean and smooth; zinc plating stage is to use the steel plate as the cathode and put it into the electrolytic solution containing zinc ions, so that the zinc ions can be restored to the surface of the steel plate through electrolysis and deposition; the post-treatment stage is to passivate the zinc plating layer, seal it and other treatments, so as to improve its corrosion resistance and aesthetics.
The product has the following characteristics. Firstly, excellent corrosion resistance: the zinc layer on its surface can effectively prevent the chemical reaction between the steel plate and oxygen and water in the air, thus prolonging the service life of the steel plate. Secondly, good processing performance: it inherits the excellent processing performance of steel plate, which can be easily cut, bent, welded and other operations. Thirdly, beautiful appearance: it has a flat and smooth surface with metallic luster, which can meet the requirements of different fields for aesthetics. Environmental protection: compared with the traditional hot-dip galvanizing process, electro-galvanizing process produces less waste water and exhaust gas pollution, which is more in line with the environmental protection concept of modern society.
Electro galvanized steel sheet is widely used in construction, household appliances, automobiles, ships and other fields due to their excellent performance and wide applicability. In the field of construction, it is mainly used for making roofs, walls and other parts; in the field of home appliances, it is used for making the shells of refrigerators, washing machines and other products; in the field of automobiles, it is widely used in the production of bodywork, chassis and other parts due to its good anti-corrosion properties and processing performance. With its excellent performance and wide range of applications, electro galvanized steel sheet has a broad prospect in the market. Especially driven by the rapid development of construction, home appliances, automotive and other industries, the market demand for it will continue to grow. In summary, as a high-quality metal material, the product has a wide range of applications and good market prospects.
