Item type:Матеріали конференцій, Optimization of the mode of thermal treatment of biocomposites filled with coffee grounds(Луцьк: ЛНТУ, 2024) Sadova, Oksana; Kashytskyi, VitaliiAn increase the duration of heat treatment leads to an increase in compressive strength, since treatment in a thermal field at a temperature of 150 °C ensures the melting of the biopolymer binder, resulting in sufficient wetting of the surface of the filler particles. This causes an increase in the packing density of the components of the biocomposite material and the formation of a significantly larger number of physical and chemical bonds.Item type:Матеріали конференцій, Formation of Glutinous Biocomposites Based on Secondary Raw Materials of Biocomposite Products(Barcelona: ACEX, 2024) Sadova, Oksana; Kashytskyi, VitaliiThe optimal content of gluten in the solution (40%) and moisture in the composition (16%) is an important technological factor that determines the strength of a new biocomposite material based on secondary raw material. It was experimentally established that the plasticity of the biopolymer matrix increases with a low content of glutin in the solution. The rigid structure of the biopolymer matrix is formed with a high glutin content. The low moisture content in the composition reduces wetting of the surface of the filler particles. A high moisture content in the composition causes the formation of a defective structure due to intensive removal of water molecules.Item type:Матеріали конференцій, Preparation of Sintered Light Termoperlites for Application in Construction(Madrid: ACEX, 2024) Sadova, Oksana; Melnychuk, MykolaThe obtained strength values make it possible to use this material in construction since the widely used ceramic brick of the M150 brand has a compressive strength of 15 MPa. Compared to other alternative materials the strength of the geopolymer filled with perlite was only 2.3 MPa, and that filled with vermiculite was 3.75 MPa. That is, the obtained strength values are higher than the average values obtained by other authors [3,5,7]. Mechanical properties correlate with the porosity of the material and its density.
