摘要: 防火服装暴露在火场环境下,其表面温度会逐渐升高,并大量传热至人体,可能会引起皮肤烧伤。通过在燃烧假人闪火实验中利用红外热像仪测试实验服装以及假人的表面温度,研究发现闪火燃烧试验结束后,通过服装传递的热量使假人的表面温度在10s内持续升高,四肢的升温速率要大于躯干的升温速率;减少燃烧时间、使用面密度较大的面料会减小这种升温幅度;而增加闪火时间、穿着尺寸较小的服装则会加大升温幅度。针对闪火燃烧试验结束后实验服装系统的散热性能,引入了新变量?–––着装假人系统的散热效能指数(γ)来进行综合表征和比较分析。

Abstract: Abstract:Under exposure to flash fire, the surface temperature of the thermal protective clothing rises gradually during the exposure, and the heat transfer to human body might cause damage to skin. In this paper, the flame manikin system and the thermal infrared camera were used to capture the surface temperature of 10 sets of protective clothing and manikin after flame exposure. The results showed that the temperature of clothing was very high during the initial stage of cooling period, and the heat transferred to the body, resulting in the increase of the skin temperature for about 10 seconds, the rising rates of the arms and the legs are higher than those of the bodies. Decreasing of burning time, application of slight fabric reduce the tendency of rising surface temperature, but increase of burning time, tight garment will increase the tendency of rising surface temperature. A new parameter―the efficiency index of the heat dissipation about the flame manikin (γ) is introduced to attribute, contrast and compare the heat dissipation after the fire exposure.

Key words: flame manikin system, fireproof suit, surface temperature, heat dissipation, infra camera
