Curtain wall is an external wall construction method that uses various strong, light and beautiful building materials to replace the traditional masonry or window-wall combination. It is surrounded by the periphery of the main structure to make the whole building beautiful, functional and safe. Wall construction method. In short, it is to put a beautiful coat on the building.
Aluminum expanded metal mesh is formed by punching and stretching aluminum plates through expanded metal punching and shearing machines, so the theoretical weight of expanded metal nets is equivalent to the weight of the steel plates required to stretch the net.
The terms about expanded metal include: long pitch, short pitch, wire stem width, wire stem thickness, overall dimension width, and overall dimension length.
Among them, the long pitch and short pitch are the data that determine the size of the rhombus mesh.
Long pitch: the distance from the center of the diagonal node of the rhombus mesh to the long direction.
Short pitch: the distance between the center of the diagonal node of the rhombus mesh and the short direction.
The stalk is a wire of the diamond-shaped mesh of the expanded metal mesh. The stalk is square, so it is divided into stalk width and stalk thickness. The length of the steel plate required for the vertical stamping of the steel plate by the expanded metal mesh machine is the thickness of the stem, and the thickness of the plate is the width of the stem.
Surface treatment
PVC dipping (plastic spraying, plastic coating), hot-dip galvanizing, electro-galvanizing, anodizing (aluminum plate), spraying anti-rust paint, etc.
Anti-rust method
1. Add some rare elements and other components to ordinary steel to change the internal structure of the metal.
2. Cover the metal surface with a protective layer to isolate the surrounding corrosive medium, so as to prevent the anti-corrosion effect. For example: Coating engine oil, Vaseline, paint or covering enamel, PVC and other corrosion-resistant non-metallic materials on the surface of steel mesh; plating a layer of zinc, chromium, nickel, etc. ; Use chemical methods to form a fine and stable oxide film on the surface of steel. For example, a fine black ferric oxide film is formed on the surface of steel parts such as machine parts and guns.
3. Frequently wipe metal equipment or place desiccants in precision instruments and add a small amount of corrosion inhibitors that can slow down the corrosion rate in corrosive media.
