摘要
为改善火场环境中防火服热蓄积的影响,将蜂窝隔热层应用于防火服中并对其热蓄积性能进行测评。选取当前典型的防火服面料,对蜂窝夹芯的边长、壁厚、芯厚进行设计并制备了21种实验试样,采用热蓄积测试仪器模拟火场环境并记录蜂窝隔热层防火服试样的热暴露时间。探究6种蜂窝孔型的边长、壁厚、芯厚的变化对实验试样热暴露时间的影响。结果表明:采用蜂窝孔型的隔热层其质量最大可减轻64%,热暴露时间最高增加了10 s;随着蜂窝孔型壁厚的增加,热暴露时间也会增加,蜂窝孔型的芯厚与热暴露时间呈正相关,孔型边长与热暴露时间呈负相关。
In order to improve the stored thermal energy of fireproof clothing in the fire environment,the honeycomb insulation layer was applied to the fireproof clothing,and its heat storage performance was evaluated. The current typical fire-fighting clothing fabrics was selected,the side length,wall thickness and core thickness of the honeycomb core were designed,and 21 kinds of experimental samples were prepared. The fire environment was simulated by the stored energy test instrument,and the minimum exposure time( MET) of the experimental samples was recorded. The influences of the length,wall thickness and core thickness of the 6 honeycomb types on MET of the experimental samples were investigated. The results show that the weight of the thermal liner can be reduced by up to 64%,and the MET is increased by up to 10 s. As the wall thickness of the honeycomb hole type increases,the MET also increases. The core thickness is positively correlated with the MET,and the side length of the hole is negatively correlated with the MET.
