In this article, let Baowu take you to understand the product of galvanized coil.
Galvanized coil is a thin steel plate with a layer of zinc adhered to the surface by immersing a thin steel plate in a molten zinc bath. It is mainly produced by continuous galvanizing process, that is, galvanized steel plate is made by continuously immersing the rolled steel plate in a plating tank with molten zinc.
So, why does the steel plate need a layer of zinc?
Galvanized can prevent rust and provide a layer of zinc protective film to the metal, and the conductive metal material repairs and enhances the color care agent;
The only double protection, synthetic metal resin protection layer and cathodic protection layer, can resist bad weather, suitable for metal long-term outer protection;
Excellent resistance to corrosion by salt and water.
Strong adhesion to various metals and their alloys, can be directly sprayed without primer, high temperature resistance, not afraid of baking, after drying, the coating can withstand high temperature of about 120 ℃. Anti-drying temperature can reach 80 ℃, fast drying. Economical and practical, one spray can prevent rust.
The anticorrosion function is not only based on the zinc content of the zinc coating, but is also influenced by the size of the particles in the zinc coating. The smaller the zinc particles, the higher the coating density, and the higher the coating quality, like a 100% high temperature plating. The role of these fine particles is to make the coating more compact, which can not only prevent corrosion, but also become a coating with a thickness of 120 μm or less to prevent the volatilization of zinc components. The successful spraying effect can make the coating thickness greater than or equal to 6mm.
What are the advantages of galvanized coil?
Coated galvanized steel sheet is very popular in adapting to various environments and has a long anti-corrosion period, but the anti-corrosion period is different in different environments.
The processing cost is low, and the anti-rust cost of galvanized sheet is lower than other paint coatings.
Durable and durable. In suburban environments, a standard galvanized sheet rust coating can last for over 50 years without maintenance. In urban or offshore areas, the standard galvanized anti-rust layer can be maintained for 20 years without repair.
Good reliability, the metallurgical bond between the zinc coating and the steel is part of the rigid surface, so the durability of the coating is more reliable.
The toughness of the coating is strong. The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
Overall protection, every part of the plated part can be plated with zinc, and can be fully protected even in depressions, sharp corners and hidden places.
Time-saving and labor-saving, the galvanizing process is faster than other coating construction methods, which can avoid the time of painting on the construction site after installation.
The above is the relevant content of galvanized coil. If you want to know more, you can pay attention to Baowu at any time.
