Product Description
Product Introduction
Galvanized coil, a thin steel plate that is immersed in a molten zinc bath to adhere a layer of zinc on its surface. The main production method is continuous galvanizing, which involves continuously immersing rolled steel plates in a molten zinc plating bath to produce galvanized steel plates; Alloyed galvanized steel plate. This type of steel plate is also manufactured using the hot dip method, but immediately after being removed from the groove, it is heated to around 500 ℃ to form an alloy coating of zinc and iron. This type of galvanized coil has good coating adhesion and weldability.
Surface Treatment
①
Passivation
The passivation treatment of the galvanized layer can reduce the formation of rust (white rust) under damp temperature storage and transportation conditions. But the anti-corrosion performance of this chemical treatment is limited and hinders the adhesion of most coatings. This treatment is generally not used on zinc iron alloy coatings. In addition to surface finishing, as a routine, the production plant passivates other types of galvanized coatings.
② oiling
Applying oil can reduce the corrosion of steel plates under humid storage and transportation conditions, and applying oil to passivated steel plates and strips will further reduce the corrosion under humid storage conditions. The oil layer should be able to be removed with a degreaser that does not damage the zinc layer.
③ paint seal
By applying an extremely thin layer of transparent organic coating film, an additional anti-corrosion effect, especially fingerprint resistance, can be provided. It can improve lubricity during molding and serve as an adhesive substrate for subsequent coatings.
4 Phosphating
Through phosphating treatment, galvanized steel plates with various coating types can be coated without further treatment, except for normal cleaning. This treatment can improve the adhesion and anti-corrosion properties of the coating, reducing the risk of corrosion during storage and transportation. After phosphating, it can be combined with suitable lubricants to improve molding performance.
Introduction to Zinc Layer
(1) Spangle coating
During the normal solidification process of the zinc layer, the zinc grains grow freely and form a coating with a clear morphology of zinc flakes.
(2) Minimized spangle coating
During the solidification process of the zinc layer, the zinc grains are artificially restricted, forming the smallest possible zinc flake coating.
(3) Spangle free
The coating obtained by adjusting the chemical composition of the plating solution does not have a visually visible morphology of zinc flakes and has a uniform and consistent
surface.
(4) Zinc-iron alloy coating
Heat treatment is carried out on the steel strip after passing through the galvanizing bath solution to generate an alloy layer of zinc and iron for the entire coating. This coating has a dark gray appearance, no metallic luster, and is easy to powder during intense forming. It is suitable for coatings that can be directly painted without further treatment, except for
general cleaning.
(5) Differential coating
For both sides of galvanized steel plates, coatings with different zinc layer weights are required.
(6) Skin pass
Finishing is a small deformation cold rolling process performed on galvanized steel plates for one or more of the following purposes.Improve the surface appearance of galvanized steel plates or be suitable for decorative coatings; Temporarily minimize the occurrence of slip lines (Luedes lines) or creases during processing in the finished product.
