Nanotechnology in the 21st century created an industrial revolution that can be seen in all aspects of our lives. This technology is not far from materials such as aluminum composite panel and tried to solve one of its related problems.
Application of Nano-aluminum composite panel
The aluminum composite panel is one of the materials that is widely used for a variety of structures, products, and buildings. In the construction, due to the cost efficiency and complexity of work, highly welcomes materials such as aluminum composite panel, which has many advantages and only few disadvantages.
At the same time, the construction profession faces numerous limitations and sensitivities. One of these sensitivities is the cleaning of towers and skyscrapers that have a composite aluminum panel appearance. Cleaning a building is important, even for low-rise buildings. However, the facade of a building and its cleanliness is involved in maintaining the appearance and value of the facade and the building as a whole. Also, in larger and more polluted cities, this importance is doubled.
But in the meantime, there are nano-aluminum composite panels that have solved this problem. In this way, in their production, nanotechnology has been used to clean the aluminum surfaces of the composite panel on its own, without the need for special chemicals and specialized methods.
How nanotechnology works in self-cleaning nano-aluminum composite panel
Nanotechnology access to different categories of levels
If you look at water droplets on some plant leaves or on a greasy surface, you will notice that the water droplets are spherical and separate from the surface. This means that the surface is almost dry and only water molecules are glued together to form spheres. This is due to the physical properties of the surface.
From this point of view, surfaces can be divided into two general categories: hydrophobic and hydrophilic, and four smaller categories: hydrophobic, hydrophobic, hydrophilic, and hydrophilic.
The hydrophilicity of a surface means that molecules of a certain amount of water are more widely dispersed on the surface. In this case, the water molecules form a narrower angle, or in other words, the height of a certain amount of water is low. In contrast, water molecules on a hydrophobic surface tend to stick to each other rather than to the surface. In this case, the water molecules from a more prominent sphere with a wider angle, and the height of the same specified amount of water is higher than in the previous case. Hydrophobic and hydrophilic cloud surfaces also have this feature intensified.
Among them, hydrophilic surfaces have very high surface energy and unlike them, the surface energy of hydrophobic surfaces is very low. At the same time, with the advent of nanotechnologies, the properties of any surface can be achieved and given a selective character. Therefore, with nanotechnology, it is possible to gain access to hydrophilic and hydrophilic surfaces and change their properties.
When a textured surface – especially a rough one – is made in another nanoscale, there is a greater distance between the air molecules and the water droplets, causing the surface hydrophilicity of the surface to decrease. Therefore, water droplets on such a surface tend to stick together more than the desired surface.
The same thing happens with nano-aluminum composite panels. Water droplets do not spread on the surface of the composite aluminum panel and stick to each other. At the same time, as they move, they absorb all the dust particles and pass through the path. Finally, the aluminum surface of the composite panel is cleaned spontaneously and without any interference from chemicals and is known as anti-dust and anti-pollution.
Also, the nano-coating on the nano-aluminum composite panel makes it difficult for dust and dirt particles to adhere to the composite panel surface on their own. As a result, there will be no strong stains on the surface of the nano-aluminum composite panel.
Of course, it is possible to clean nano-aluminum composite panels and any other aluminum composite panel with detergents and tools; Aluminum composite panel does not require special tools and materials for cleaning and it is easy to clean, But the important thing about nano-aluminum composite panel is that it makes the issue of cleaning the composite panel surface and facade of tall buildings completely unnecessary.
Advantages that come with the self-cleaning attribute of the nano-aluminum composite panel
The fact that the nano-aluminum composite panel cleans and keeps itself clean has these advantages:
- Saves money and energy every year to clean the facade of the building.
- The facade of the building last longer.
- The building and its facade remain the same as in the early days, and this preserves the value, prestige, and status of the building, its owners, and architects.
Nano-aluminum composite panel coating as a protector
Nano-aluminum composite panel, like any other composite aluminum panel, consists of several layers: the core or central layer, the front, and rear cladding layers, and finally the coating layers; Nanotechnology is applied in this layer. In fact, this type of composite panel is a nano-coated composite aluminum panel that acts as a protector. This protection can be defined in other ways as well. Such as:
- Resistant to urban pollution
- Oil resistant
- Anti-wear
- Resistant to sun rays
- Resistant to changing weather conditions
- Resistant to strong acidic and alkaline substances
In fact, the nano-aluminum composite panel has all the previous traditional properties of aluminum composite panels such as anti-corrosion, anti-scaling, high strength, integrated performance in the earthquake, and other cases, but in many ways, such as resistance to external factors, more resistant it is.
