Porovnání chování materiálů při různých rychlostech nárůstu teploty během termické analýzy

Abstract

The aim of this thesis was to analyze and compare the behavior of materials at different heating rates within the context of thermal analysis. The theoretical section is divided into chapters devoted to thermal analysis, the simultaneous TGA and DSC method, thermodynamics, kinetics, and heating rates. The practical section presents the thermoanalytical instrument used, defines the methodology of the work, and describes the behavior of selected materials at different heating rates. The comparison confirmed the expectations arising from the literature review. The findings can be used for analyses conducted in the thermal analysis and fire reaction laboratory at the Faculty of Safety Engineering, VŠB – TUO.
