Встановлення закономірностей формування властивостей вогнестійких біокомпозитів на основі гібридного вяжучого

TL;DRAbstract

The process that forms the properties of fire-resistant biocomposites based on wood sawdust and a binder from a mixture of gypsum and an intumescent coating based on PVA dispersion has been investigated. The task addressed is to ensure the stability of biocomposites based on a gypsum binder to changes under operating conditions. This is important since the production of biocomposites from renewable sources for construction is relevant. It has been proven that when thermally exposed to the biocomposite samples, no ignition occurred, the maximum temperature of the flue gases was about 84°C. When using a gypsum binder, a non-combustible structure was formed on the surface of the biocomposite, which prevented the sample from igniting. For a biocomposite based on a binder from a mixture of gypsum and an intumescent coating based on PVA dispersion (hybrid binder), charring of the sample surface is characteristic, which prevents its ignition. In addition, the results of determining the proces
