    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 Sergiivna
    Researching 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.

    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 Sergiyovich
    Researching 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.

    Hybrid eco-friendly biodegradable construction composites modified with humic substances
    (Odessa State Academy of Civil Engineering and Architecture, 2022) Lebedev, V. V.; Miroshnichenko, D. V. ; Mysiak, V. R.; Bilets, D. Yu.; Tykhomyrova, T. S.; Savchenko, D. O.
    Obtaining hybrid eco-friendly biodegradable structural composites was considered. The aim of this work was to determining the properties of hybrid eco-friendly biodegradable construction composites modified with humic substances. Hybrid eco-friendly construction composites were obtained on the basis of bioplastic polylactides with the addition as a filler of coffee grounds with a polyfractional composition within a particle size of 0.5 mm to 1 mm and a hybrid modifier – humic substances from brown coal. Hybrid ecofriendly construction composites were obtained by extrusion of pre-prepared raw materials in a single-screw laboratory extruder at a temperature of 170–200 °С and an auger rotation speed of 30–100 rpm. Investigated impact strength, breaking stress during bending, melt flow index (MFI) and melting temperature of hybrid ecofriendly biodegradable structural composites modified with humic substances. Optimization studies have been carried out to determine the most effective composition of new ecofriendly structural composites based on bioplastics of polylactides, coffee grounds waste and humic substances of three different types. Researching data together with the data of impact strength, allows us to make assumptions about the possibility of forming a variety of products from structurally composite material, herewith a composition with a coffee content of 50 % by mass. deserves a special attention. The data show an increase the impact strength and the breaking stress during bending a hybrid modification of ecofriendly biodegradable construction composites based on polylactide, coffee grounds waste and humic substances in 2.5 times, with optimal in terms of strength characteristics is the content of coffee grounds at 50 % wt. and 0.5 % by mass humic substances with the highest content of volatile substances and the lowest content of carbon. For such hybrid ecofriendly biodegradable construction composites based on polylactide, coffee grounds waste and humic substances, the MFI is characterized by 3.1 g/10 min. and the processing temperature range is 182–188 °C. It is shown, that the designed hybrid eco-friendly biodegradable structural composites modified with humic substances can be used in the production of high-strength structures and elements for engineering purposes.
