Physico-technical approach to design of composites from mineral and polymer technogenic resources

Abstract

<p class="R-AbstractKeywords"><span lang="EN-US">Artificial composite materials are currently being produced in large quantities, they are diverse and they are widely used in the economy. There have been extensive theoretical and experimental studies of different types of components, developed the calculation methods of composites production with predefined properties.</span></p><p class="R-AbstractKeywords"><span lang="EN-US">At the same time industry produces a lot of mineral and polymer waste, which are practically technogenic resources, but their use is currently at quite low levels. The paper examines the possibilities to use technogenic resources- mineral (such as ash and clay) and organic (polymers -PET containers) for producing qualitative composite materials. For this purpose theoretical analysis and calculations of the physical properties of components and process parameters that determine the operating characteristics of the composite material were carried out.</span></p><p class="R-AbstractKeywords"><span lang="EN-US">Composite-forming process efficiency determinative parameters were analysed: adhesion, the specific surface energy, specific free surface, adsorption capacity and the degree of dispersion of the particles.</span></p><p class="R-AbstractKeywords"><span lang="EN-US">The role of external factors in processing of composite were examined – temperature, concentration of components.</span></p><p class="R-AbstractKeywords"><span lang="EN-US">The characteristics of prepared samples of composites showed the possibility to use these waste for the development of qualitative products for different purposes.</span></p>

Upcycling of Technogenic Mineral Waste – Challenges and Solutions

“…In this work, based on our previous research from the 1990s on the complex and rational use and processing of mineral and technogenic resources [1], [2], [3],[, [4], [5] as well as on the analysis, compilation and calculation of literature data provides a methodology for evaluating and substantiating the prospects for the processing of technogenic mineral materials. The main thesis on which this methodology is based is the concept of up cycling.…”

Eco-Innovative Solutions for the Processing of Technogenic Mineral Resources

“…It is known that significant part of waste produced in the industry have inorganic nature [1,2] In our previous investigations [3,4] we declared that all solid waste which are inorganic in the terms of chemistry are mineral waste. They include: the remnants of the construction and repair, debris , byproducts of mining , construction and demolition waste, glass and glass-use industrial waste , ceramic waste, combustion waste, and so on .…”
