Glass is an indispensable material in our lives, and it has been widely used in our social life. For example, glass is used in doors and windows, car glass, glass curtain walls, etc. After a long time of use, glass will become dirty and difficult to clean on high-rise buildings. So, how can we solve the problem of anti fouling of glass? Let the glass clean itself! Next, let's take a look!
Nowadays, most buildings are high-rise constructions, and the exterior walls are decorated with various materials of glass. The glass curtain walls and windows of high-rise buildings are prone to dust accumulation and require frequent wiping to maintain cleanliness and indoor brightness. Cleaning glass requires outdoor and high-altitude operations, and must be carried out using high-altitude lifting plates, platforms, and other transportation tools. Spider man operations are highly dangerous and require long-term repetitive cleaning, which is very short-lived and not only time-consuming but also costly, affecting aesthetics. Of course, due to the emergence of this problem, a type of glass called self-cleaning glass was invented.
Easy to clean glass is often referred to as self-cleaning glass in commercial terms, and belongs to the eco-friendly "green glass" category. It refers to the application of a special coating on the surface of glass, which makes it difficult for dust or contaminated liquids (including those containing water or even oil) to adhere to the surface of the glass, or to be easily washed away by water (or rainwater). This makes the glass surface very easy to maintain cleanliness, reduces the trouble of cleaning the glass surface, and can also save increasingly scarce water resources.
The "easy to clean coatings" or "self-cleaning coatings" used on glass and ceramic surfaces on the market can be roughly divided into three categories:
1. The main component is composed of silicone (or silicone agricultural production system resin) or other oily materials.
When applied to the surface of the material, it gives a feeling of oiliness, but it does not react with the silica molecules on the surface of the material to form a strong nano film. Instead, it only fills the uneven surface that we cannot see with the naked eye, making the material surface smooth and uniform. Its advantage is that it has a strong repulsive effect on water (but not on oil), but its adhesion is poor. In a short period of time (6-12 months), its water repellent properties will be greatly reduced.
2. The main component is titanium dioxide (TiO2).
After coating a layer of titanium dioxide film on glass, titanium dioxide exhibits superhydrophilicity due to its excellent photocatalytic properties under the action of ultraviolet light energy. By utilizing this superhydrophilic property (opposite to its hydrophobic property), it causes small water droplets to converge into large ones, which fall off under the action of gravity, making it easy for stains to be washed away by water and giving the glass an easy to clean property. Therefore, it is particularly suitable for outdoor building glass. Its advantage is that it is cheap, but its disadvantage is that it requires UV irradiation and its adhesion is also poor.
3. The main component is inorganic nano silicon material, which is characterized by a super hydrophilic coating on the surface and good dust resistance.
It does not rely on sunlight and works in a completely dark environment. It is an upgraded version of titanium dioxide products.
Self cleaning glass has this function, choosing self-cleaning glass for high-rise building glass decoration is the best choice. Self cleaning glass can play a self-cleaning role, reducing the trouble of cleaning glass and saving water resources.
