Abstract
Technology of production of heat-insulating boards based on modified stems of Heracleum Sosnowskyi
Incoming article date: 15.03.2024A technological scheme for the production of biostable materials based on monoethanol-modified (N→B)-trihydroxyborate (MEATHB) stems of Sosnovsky's borer and polyurethane binder has been developed. This technological scheme differs from the traditional one in that it includes the process of plant raw material modification to ensure its biostability. The paper presents the results of determining the thermophysical properties of the obtained thermal insulation boards, as well as the results of assessing their biostability. The obtained results correspond to the current requirements for thermal insulation materials. The paper analyzes the main stages and processes necessary to create a high-quality and environmentally friendly product. The main types of plant raw materials used in the production of thermal insulation materials are considered, as well as the features of technological processes associated with its processing and formation. In addition, the advantages of using plant materials in the production of thermal insulation materials from the point of view of ecology are presented.
