摘要
利用iConeR全自动锥形量热仪和STA 449 F3同步TG-DSC热分析仪,研究消防员灭火防护服在50 kW/m^2热通量下的热稳定性和热释放特性,并利用BX53型热台偏光显微镜观察550℃下灭火防护服表面形貌微观变化。实验表明,外层面料对热释放性能起到主要影响。消防员灭火防护服在高温下热失重较多,在553.13℃左右4层面料同时快速失重,各层质量均降至10%以下。升温过程中的表面形貌变化在微观上表现为与热失重的相关性。
The i Cone R automatic cone calorimeter and STA 449 F3 synchronous TG-DSC thermal analyzer are used to study the thermal stability and heat release characteristics of protective clothing for fire fighting under heat flux of 50 kW/m^2,and the mechanism of microscopic change of surface morphology under 550℃was observed by BX53 hot stage polarized light microscope.The experiment showed that the outer fabric plays a major role in the heat release performance.The protective clothing for fire fighting has more weight loss at high temperature.The four-layer fabric loses weight quickly at the same time at 553.13℃,and the quality of each layer drops below 10%.The change of surface topography during heating is microscopically related to thermal weight loss.
