The article shows that techno-genic fillers, based on slag of electrometallurgical production, can be used as fillers for water-dispersion paints, based on polymer composition. For these purposes, it is necessary to modify the slag particles, in order to increase its hydrophobic property. The article examines the effect of the mass of the additive of techno-genic filler, based on the modified slag of the electrometallurgical plant, on the properties of the resulting paint. A water-dispersed acrylic composition, containing stearic acid-modified slag of electric steelmaking production as a filler, has been developed. The composition has high uniformity, is more heat-resistant and water-resistant, a high hiding power and viscosity, and corresponds to modern analogues.
The paper discusses current environmental problems associated with the accumulation and disposal of municipal solid waste in Russia by the example of the Belgorod region. It is shown that the existing rates of waste accumulation can lead to environmental emergencies in the region. The scenarios for the development of emergency situations at the landfill of Belgorod were considered. The analysis show that the most dangerous in terms of the social and environmental consequences of dangerous situations are scenarios related to the filtering of the contents of the map-ditches into the environment. Also, the high integral risk has a scenario with pollution of atmospheric air of polygon gases. Using the method of risk matrices by formalizing expert opinions, it is shown that a comprehensive method of disposal of solid waste minimizes anthropogenic pressure on the environment in the field of waste management.
The microstructure of gas silicate wastes is investigated. It is established, differences in particle size distribution affect rheology, abrasivity, abrasion resistance and material strength. The kinetics of polymerization of epoxy binders in the initial and filled samples is investigated: filler particles prevent the crosslinking of polymer molecules, breaking the bulk structure of the polymer matrix. As a result of research, the possibility of directional regulation of the physicomechanical properties of epoxy com-posites due to the introduction of dispersed fillers is shown, giving the binder complexes higher physi-comechanical properties, which expands the areas of their application in most industries. The theoret-ical justification is that the thermal parameters of the filler are much lower than the parameters of the main raw material. At the same time, the porosity of the filler material due to its own pores and heter-ogeneous materials formed during mixing gives the effect of thermal energy absorption, which ulti-mately leads to an increase in the thermal resistance of the samples and a slight decrease in the ther-mal conductivity coefficient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
