Anodized Aluminum - The Material of Choice for Architectural Curtain Walls

In its natural environment, aluminium naturally forms a thin oxide film, which has certain protective properties. However, the surface of this untreated aluminium is very susceptible to physical damage and chemical corrosion. Aluminium oxide curtain walls are made from anodised aluminium, which, after a special chemical reaction, forms a protective film on the surface that insulates it from air and oxygen, thus achieving antioxidant properties. At the same time, also because of its good appearance also has a rich metal texture, so the building also has a better decorative effect, fashionable appearance, modern atmosphere.

What is aluminium oxide plate? As we all know that the modern building commonly used aluminium plate surface is usually sprayed as the surface of the human face to do a layer of make-up treatment and oxidized aluminium plate is through a special process to promote the oxidation of the aluminium surface to form a protective film to improve the performance of aluminium plate and the principle. You can understand for similar photorejuvenation beauty, because the protection of the oxide film can not be stripped out, and it is more worth mentioning that the modern aluminium plate process treatment of oxidation technology is mainly based on anodic oxidation, the so-called anodic oxidation of aluminium is a kind of electrolytic oxidation process. Aluminium plate as the anode placed in the electrolyte solution, the use of electrolysis, so that the surface of the formation of aluminium oxide film process, known as the anodic oxidation of aluminium plate. The cathode in the device is a material with high chemical stability in the electrolytic solution. The principle of aluminium anodising is essentially that of water electrolysis. Aluminium as the anode is oxidised by the oxygen precipitated on it, forming an anhydrous aluminium oxide film, and not all of the oxygen generated interacts with the aluminium, but part of it is precipitated in a gaseous form.

So what's so amazing about anodised aluminium panels? Simply as following:

(1) Good processability: anodic oxidized aluminium has strong decorative properties, moderate hardness, can be easily bent into shape, continuous high-speed stamping, easy to directly processed into products, without the need for complex surface treatment, greatly shortening the product production cycle and reducing the cost of product production.

(2) Good weather resistance: the standard thickness of the oxide film (3μm) of the anodized aluminium plate indoor use for a long time without discolouration, corrosion, oxidation, rust. The anodized aluminium sheet with thickened oxide film (10μm) can be used outdoors and can be exposed to sunlight for a long time without discolouration.

(3) Strong sense of metal: the surface hardness of the anodized aluminium plate is high, up to sapphire level, with good scratch resistance, and the surface is not covered by paint, which retains the metallic colour of the aluminium plate, highlights the modern sense of metal, and improves the product grade and added value.

(4) High fire resistance: pure metal products, no paint and any chemical substances on the surface, 600 degrees high temperature does not burn, does not produce toxic gases, in line with fire environmental protection requirements.

(5) Strong stain resistance: no handprints, no stain marks, easy to clean, no corrosion spots.

(6) Strong applicability: Wide range of uses, suitable for metal aluminium ceilings, curtain wall panels, aluminium-plastic panels, fireproof panels, honeycomb aluminium panels, aluminium veneer panels, electrical panels, cabinet panels, furniture panels and so on.

The most important thing for designers is that aluminium panels have a stronger metallic texture and higher value! The anodic oxidation treatment itself is relatively mature technology architecture is also very widely used.
