Study on the fire hazard determination system of thermal unstable material
Ying‐Chun Chen · Fire Science and Technology · 2005
Taking ordinary timber as the study object,the different aging conditions of the timber were simulated.TG-DTA thermal analysis was used to conduct thermal analysis under the different temperature-rise rates and different experiment conditions in order to analyze the reaction mechanism of timber decomposition and combustion.Dynamics parameters have been got.Assessment system of thermal unstable material has been studied.Comprehensive parameters have been used to assess the thermal unstability of the materials.Their relative changing tendency of the risk and safety has been analyzed.
