“…The mineral wool blanket was heat treated by suction of the heat carrier (air heated to 200-240°C) through the blanket layer. In this case, moisture is evaporated from the blanket and the binder is cured [13][14][15][16]. The purpose of the heat treatment is to stabilize the structure of the blanket by curing the binder, which occurs as a result of polycondensation reactions.…”

This article describes results of modelling of heat treatment of mineral wool blanket. The properties of mineral wool products are largely determined by the conditions of heat treatment, which is carried out by suction of the heat carrying agent through a layer of mineral wool blanket. The choice of technological parameters and optimization solutions determines both the energy costs of manufacturing mineral wool products and their properties and the stability of these properties over time when used in structures. Optimizing the heat treatment parameters of a mineral wool blanket is a labor-intensive and time-consuming task. The development of accelerated methods based on the analysis of the results of previously conducted and new studies can significantly reduce the time for choosing technological parameters, as well as increase the reliability and adequacy of decisions.

“…During the Second World War, research and technological work were dis-continued everywhere with the exception of the United States. This allowed the United States to master the large-scale production of foam glass, mainly for the needs of the Navy, and then for many years to become a leader in the production and research of this technology [7][8][9].…”

The article presents the results of a study of the state of production of a foam glass and the nomencla-ture of its products. It is shown that it is expedient to use the recycled glass obtained from the bottle battle, the defective glass and the double-glazed windows as a raw material for the production of the foam-glass. The re-quirements are formulated for glasses, which should have low viscosity values in the range of foaming tempera-tures. The features of the technology for the production of the foam glass aggregate at the specialized lines are outlined. The technology features are the composition of the charge and temperature conditions of burning. The mixture for the production of the foam glass aggregate consists of glass flour, organomineral blowing agent con-taining water and food glycerin, as distinct from the slab foam glass, where soot or coke is used as a blowing agent. The results confirm the effectiveness of the use of the foam glass aggregate as a soundproofing backfill for floors. Currently, about 70% of the foam glass aggregate is used for roofs and stylobates; the rest is used in landscape design, road construction, foundations and major repair. In the future, the areas of application of the foam glass aggregate can be significantly expanded in the direction of building systems, lightweight aggregates, etc., which involves in-depth studies of the properties of this material.

“…Technological processes are organized in such a way as to minimize the negative impact on the environment. Saving heat by reducing losses through an insulating jacket should, in an economically feasible time, recoup the energy costs of manufacturing materials and installing them in insulation systems [11][12][13]. Products from unstitched expanded polyethylene (pipes, rolls, sheets) have been used as insulation since the beginning of the 90s and now we have gained sufficient experience for use of them.…”

The article, on the example of pipeline insulation systems, outlines the fundamentals of the concept of environmentally sustainable construction, including requirements for materials, constructional systems in which these materials are used, engineering systems and work technologies. Insulation based on polyethylene foam technology of its installation meets the requirements of EcoMaterial Basis or EcoMaterial Green. Polyethylene is absolutely safe for humans and its base is polyethylene, which used in the food industry (packaging or boxing) and in medicine (prosthetics). A specific feature of polyethylene foam, like most types of foamed (gas-filled) plastic materials, is combustibility, expressed depending on the consumption and effectiveness of flame retardants, to one degree or another. During operation in the temperature range from -60 to +90 °C, the properties of materials are stable and no harmful emissions occur. The installation of the insulating sheath fixed by an glue method and is not associated with processes that are dangerous for humans and harmful to the environment. The article presents the main provisions of methods for calculating insulation systems based on polyethylene by measure of energy efficiency, which is defining, including the environmental assessment of insulation systems. The optimum thickness of polyethylene foam has been determined, as well as the recommended insulation thicknesses to ensure a given (safe for humans) temperature; to prevent moisture condensation on the surface of the insulating layer. An calculated time has been established during which thermal insulation prevents cold water from freezing when at an emergency stop of its movement in pipelines in the winter.
