Today, nanotechnology in construction looks quite impressive: structural materials with rare characteristics, new varieties of reinforcing steels, unique films, wear-resistant coatings and flexible self-cleaning glasses. All this only proves that the scientific development and use of nanotechnology in modern life are of great importance. At the national level, programs have already been adopted for their development in thirty-five countries of the world.
Nanotechnology in Construction: Airgel
Airgel (frozen smoke or solid air), which is included in the Guinness Book of Records, is recognized as the most unusual human creation.
This material, which has high-tech properties, was synthesized at the beginning of the twentieth century, but it has found application only today. It is a gel, the liquid phase of which is replaced by a gaseous one. Airgel resembles a polystyrene foam or a solid foam. Having a strikingly low density, it possesses many important properties, such as hardness, heat resistance, transparency and others.
Airgel can withstand a load of thousands of times its weight. Materials based on it are widely used for thermal insulation of equipment and in various fields of construction.
Such heat insulators have a wide temperature regime, which varies from -270 to +385 degrees.
Airgel is an absolutely safe material for the environment and for humans, as well as durable in use. Disposal of this material is much more convenient and simpler, since its volume is much less than that of traditional materials used in construction.
Nanotechnology in construction: adhesive Teflon fabric
The newest multifunctional product with a wide spectrum of action is a fabric made of heavy-duty fiberglass with a non-stick Teflon layer, which is impregnated on the back with glue.
In construction, adhesive Teflon fabric is used recently, but already quite actively. This fabric is resistant to weather conditions and aging; spots of varying complexity are easily removed from its surface. It is quite resistant to the chemical effects of alkalis, acids and organic compounds, and its completely smooth surface remains absolutely clean for five years. In addition, Teflon fabric has excellent insulation characteristics.
Its service life is at least 25 years, it does not harm the environment at all, since it does not contain toxic additives. But the main advantage of such a fabric as building material is its fire safety.
Glue Teflon fabric is used today in almost all industries, for example, in aviation, in paper production, in printing technology, in sewing clothes, in medicine, in mechanical engineering and in construction.
Nanotechnology in construction: plastic foil
Plastic foil is unique in several ways. The first positive quality is its profitability. Unlike glass, this foil has the best throughput of ultraviolet rays and has impeccable insulation performance at various temperature conditions.
This foil does not need special care, since during rain all impurities are washed off without a trace.
An important quality of this polymer is that it is not traumatic. The weight of the foil is about one percent of the mass of glass necessary for glazing the same area of the room.
In the past ten years, the use of nanotechnology and materials based on them has become popular and commonplace in everyday life.
