The production process and production process of colour coated sheet
The production process and production process of colour coated sheet
The production process of colour coated sheet: on the continuous unit, cold-rolled strip steel and galvanized strip steel (electro-galvanized and hot-dip galvanized) are used as substrates, and after surface pretreatment (degreasing and chemical treatment), they are coated by roller coating method. One or more layers of liquid paint, after baking and cooling, the resulting sheet is the coated steel sheet. Since the coating can have various colors, it is customary to call the coated steel shee...

Corrosion resistance of galvanizing steel plate
Corrosion resistance of galvanizing steel plate
After the galvanizing steel plate is galvanized, the surface properties are very different from ordinary steel plates. In terms of anti-corrosion coating, most paint coatings can be applied to ordinary steel plates, but the anti-corrosion coating of galvanizing steel plate is a problem. frequent. The main reason is that the surface of the galvanizing steel plate is smooth, and the adhesion of most paints cannot achieve a good effect, resulting in the peeling of the paint film, which cannot pl...

Five classifications of galvanized steel sheet
Five classifications of galvanized steel sheet
What are the types of galvanized steel 1. Hot dip galvanized steel sheet The sheet steel is immersed in a molten zinc bath, and a sheet of zinc is adhered to its surface. At present, it is mainly produced by continuous galvanizing process, that is, galvanized steel plate is made by continuously immersing rolled steel plates in a plating tank in which zinc is melted. 2. Alloy galvanized steel sheet This kind of steel plate is also made by hot-dip method, but after it is out of the tank, it is ...

What material is the color aluminum coil plate
What material is the color aluminum coil plate
The color aluminum coil plate material refers to the solution of the surface layer of the aluminum alloy profile, because the characteristics of the aluminum alloy profile are very stable and not easy to corrode. Generally, the surface layer can be guaranteed to not fade for 30 years through special solutions, because the relative density is small, the strength is high, and the size of the enterprise is high. The weight is small in the metal material, and the colorful aluminum is a new type o...
