The Zinc Layer.
The cathodic protection will last as long as the zinc layer is present.
The zinc layer of the pole is not less than 75 microns.
Check if the component is damaged, bent,twisted, and if the zinc layer is damaged.
The Zinc layer provides excellent corrosion resistance and prolong service life.
They have high resistance to corrosion due to the zinc layer and paint layers. .
The zinc layer of raw material used by Wetterbest® ranges from 225 to 275 g/sqm.
Check whether the component is damaged,bent or twisted, and whether the zinc layer is damaged.
In the fillet weld, make sure the zinc layer is melted and vaporized as much as possible.
As far as the raw material is concerned, the most important features are the type of steel used,the thickness of the sheet, the zinc layer and the paint layer. .
In an aggressive environment, the zinc layer becomes thinner, but the carrier part of the support remains intact.”.
The size, brightness and surface appearance of zinc spangles depend on many factors, butit is mainly related to zinc layer composition and cooling methods.
The thicker the zinc layer, the more difficult it is to the oxygen in the atmosphere to reach the base material, the iron, the basic steel component.
The thickness of galvanized layer is generally 20um and the zinc layer brings difficulties to the welding of galvanized steel.
The organic coating on the zinc layer provides coverage and protection against rust and the service life is about 1.5 times longer than that of the galvanized steel.
Firstly, move the end of the electrode forward about 5~7mm,melt the zinc layer and then return to the original position to continue the welding.
Since the zinc layer of the electrogalvanized plate is thin, the zinc content is usually 20/20g/m2, so the product is not suitable for use.
Normal spangles(N): it is not required to control the solidification process of zinc layer, and various sizes of zinc blossom or no blossom are allowed;
As the zinc layer of the zinc electroplating board is thin and usually contains 20/20g/m2, this product is not suitable for outdoor wall and roof making.
Minimized spangles(M): it is required to control the solidification process of zinc layer to obtain tiny zinc blossom(usually invisible to naked eyes).
The zinc layer near the groove will produce oxidation and evaporation under the action of arc heat and form ZnO white smoke and vapor, which is easy to cause porosity in the weld.
Minimized spangles(M): It is required to control the solidification process of zinc layer to obtain relatively uniform and small size zinc flower still visible to the naked eye;
Because the zinc layer of the electro-galvanized sheet is thin, the zinc content is usually 20/ 20g/ m2, so this product is not suitable for use Make walls, roofs, etc. outdoors.
Normal spangles(N): It is not required to control the solidification process of zinc layer, and various sizes of zinc flake can be generated during the natural solidification process;
Furthermore, the zinc layer protects the steel from corrosion and keeps the paint layer unaffected for a long time and ensures a pleasant appearance on both sides of the fence shingles.
Cold galvanizing is a physical treatment essentially, because the coating is thin that generally within 5-30 um,so the corrosion resistance relatively is weak and the zinc layer is easy to fall off.
During the solidification of the zinc layer, zinc grains are artificially restricted to form zinc coating as small as possible.
In addition, the zinc layer on the surface and edge of the steel pipe groove will produce oxidation, melting, evaporation and even volatilization of white smoke and steam under the action of arc heat, easily causing weld pores.
In addition to the protection of the zinc layer, the organic coating on the zinc layer plays a protective role to prevent the steel band from rust.
