Документ Study of brown coal humic substances hybrid modification on sorption resistance of biodegradable materials("Interdruk" Poland, Warszawa, 2023) Lebedev, Vladimir Vladimirovich; Miroshnichenko, Denis Viktorovich; Tykhomyrova, Tetyana SergiivnaResearching on brown coal humic substances hybrid modification of biodegradable materials based on pol ylactide and coffee waste for their sorption resistance in different liquid mediums are carried out in this work. The objects of study were extrusion polylactide of the Terramac TP-4000 brand, coffee grounds waste with article size limit from 0.5 to 1 mm, dried to moisture content 0,5% and humic substances, which were obtained by extraction of brown coal. The obtained diffusion coefficient values of different liquids are in the range from 0,95 * 10⁻¹⁰ to 6,65 *10⁻¹⁰ m²\sallow us to conclude that the designed brown coal humic substances hybrid modified biodegrada ble materials based on polylactide and coffee waste can be used as a polymer base in terms of their sorption properties for one and multi-use tableware production.Документ Brown coal humic substances hybrid modified biodegradable composites wear simulation("Interdruk" Poland, Warszawa, 2023) Lebedev, Vladimir Vladimirovich; Miroshnichenko, Denis Viktorovich; Tykhomyrova, Tetyana Sergiivna; Kochetov, Mykyta SergiyovichResearching on wares modeling from brown coal humic substances hybrid modified biodegradable composites based on polylactide and coffee waste technology are carried out in this work. New wares are pots for seedlings and vases for planting greenery that can be used for landscaping for urban territories. The products design was made, the mathematical modeling of the designed products was carried out. The process of modeling products based on brown coal humic substances hybrid modified biodegradable composites based on polylactide and coffee was carried out in the SolidWorks 2020: 3D CAD environment with subsequent receipt of g-code, which is intended for machines for the production of molds for plastic injection.
