Документ Production of modified basalt fibre for heat-insulating products manufacturing(IOP Publishing, 2019) Gots, V. I.; Berdnyk, O.Y.; Rogozina, N. O.; Maystrenko, А. А.As a result of the research flexible heat-insulating materials were developed based on basalt fiber with increased effectiveness, which can be achieved due to directed fiber microstructure forming through fusion modification. It is known that chemical composition of initial fusion not identically influences on physical and chemical and mechanical properties of basaltic fibres. Structural descriptions of fusion and basaltic fibre got from him appear main factors the nearer, than high speed of cooling. This index mainly depends on such constituents: а) ambient temperatures; b) coefficient of heat conducting; c) heat conducting of fusion; d) areas of surface. By researches influence of temperature of basaltic fusion was shown on the structure of fibres. Structural characteristics of the basalt fiber (number of active zones, coefficient of its distribution on the basalt fiber surface, as well as a correlation of three groups of active zones) depend on rheological properties of basal fusion, speed of drawing through the die plate and cooling speed.Документ The influence of technological factors on the properties of basalt fiber when used in the manufacture of flexible heat and sound insulating products(Proceedings of the 3rd Annual Conference “Technology transfer: fundamental principle and innovative technical solutions”. Tallin, Estonia, 2019) Berdnyk, OksanaAnalysis of energy efficiency and operational safety of technological equipment of industrial enterprises, engineering networks, buildings and structures, building structures in many sectors of the economy, including the housing and industrial sectors, causes interest in the use of high-tech, environmentally friendly heat and sound insulation materials with enhanced performance properties. One of the relevant representatives of these materials is basalt fibers and their use as raw materials in the production of flexible heat and sound insulating products. It is known that the chemical composition of the initial melt equally affects the physicochemical and mechanical properties of basalt fibers. The main influence factors, including the chemical composition, are the thermal past of the melt, the method for producing basalt fiber and the conditions for the formation of its structure. These factors determine the structural characteristics of the fiber and, as a consequence, its physicochemical characteristics. The degree of fiber strength is directly determined by its chemical composition and production method. The greatest strength of the fiber is obtained by ensuring the perfect fiber structure in the absence of ruptures of siliceous chainsДокумент INVESTIGATION OF PROPERTIES OF MODIFIED BASALT FIBERS(2018) Gots, Volodymyr; Palchyk, Petr; Berdnyk, OksanaThermophysical, physical-mechanical and acoustic characteristics of a rough continuous basalt fiber under the influence of operating factors and a corrosive environment are studied. It is shown that the production of protective materials with high thermophysical and acoustic properties is possible when creating a porous system with a known texture characteristic of pores of different classes, purposes and connections. An influence of the porous system of rough continuous basalt fiber on the operational properties of flexible heat and sound insulation products and materials is studied. The requirements of normative documents on thermal protection of buildings and structures have caused a constant tendency from the creation of new materials that ensure reliable operation of structures and equipment in the conditions of intensive influence of destructive factors of external influence. This led to an increase in requirements for walling wall materials that are used to fill openings in frame construction, or as an independent structural and thermal insulation material when building buildings with load-bearing walls. They are presented with a set of requirements that combines: physical and mechanical, chemical, hygienic, thermophysical, decorative and finishing, and other properties of the material. In this connection, there is a need to create materials that, having a small average density and high strength, are able to withstand the temperature loads, and the influence of an aggressive environment. It is determined that the performance characteristics of flexible heat and sound insulation materials are directly proportional to the degree of porosity of the composite materials and their structural characteristics. It is shown that the increase in the operating temperature of these materials, sound and thermal resistance is determined by the chemical and mineralogical composition of the initial materials and their structural characteristics. The influence of the mechanism of selective leaching of coarse continuous basalt fibers on their texture characteristics and the operating temperature zone is studied. The resulting material is produced from environmentally friendly raw materials using a one-stage technology without harmful effects on the environment and, unlike thermal insulation materials based on polymers or asbestos, has no harmful effect on the human body, meets the requirements of the European Union for the protection of the environment and sanitary and hygienic standards.Документ Мікропориста структура грубих базальтових волокон і їх структурні характеристики(ОДАБА, 2019) Гоц, В.
