Technology for protecting building envelopes in construction using magnetron sputtering

The global environmental agenda is aimed at saving energy resources in all areas of human activity. An important condition for energy saving and increasing energy efficiency is the thermal protection of buildings and structures of all types. Currently, when designing and constructing buildings, structurally oriented solutions are needed to provide conditions for the implementation of modern innovative technologies. At the same time, when producing new thermal insulation (heat-protective) materials, it is necessary to take into account such important issues as environmental friendliness and ensuring a comfortable microclimate. Issues of indoor air exchange are extremely important, especially during the spread of new viral infections. Thermal insulation (thermal protection) of buildings must ensure air circulation, that is, be vapor permeable. Polyester material has this property. Modern technologies make it possible to impart heat-reflecting properties to such materials by applying metallized nanolayers or their compounds to their surface. Among the methods for applying such layers, a special place is occupied by the magnetron sputtering method, which is used in the technology of applying protective coatings to the surface of products made from roll and sheet materials. With the development of applied technological research in the chemical industry, many substances (compounds) were invented, some of which gained such popularity that they began to be used in the production of a huge number of materials, including in the construction industry. One of these substances was polyester as a high-molecular compound, which became widely used in many areas of industry. Polyester material is often combined with other man-made or natural fibers. Among them: cotton, linen, wool, polyamide. As a result, we obtain a canvas (materials) with new characteristics, adding new unique properties, such as strength and wear resistance, does not fade in the sun, and does not require special care. Polyester fabric is used for suspended ceilings and in building materials. Its high density of 250 kg per cubic meter allows this to be done. By combining the production of polyester and cotton, the material acquires the properties of breathability, hygroscopicity and low thermal conductivity. The purpose of this article is to describe the technology of the ion-plasma processing method of combined linen materials with possible application in the construction industry.
