摘要
消防服有隔绝热源、保护消防员的作用,新角度下消防服热传递机理分析有助于改进设计和提升热防护性能。构建一个消防服系统与火场进行能量交换的热力学体系,探究了该系统中热动微团的分子运动形式及粒子热动能输运模型;剖析了消防服作为高温火场与低温"消防服系统"界面时的传热模型;论述了火场环境中消防服的传热机理;从燃烧和热能输运角度分析了消防服阻燃机理,提出了一些初步的热力学阻燃体系构建思路。这为进一步的消防服传热机理研究奠定基础,也为热防护服的服装结构、面料、纤维等开发设计提供参考。
The important function of firefighting uniform was to isolate heat source and protect firefighter in fire.Appropriate analysis method of fire suit transmission mechanism could attribute to improve the design of firefighting clothing and its thermal protection performance.The thermodynamic system for the energy exchange of the fire suit system in fire was envisaged.Under the system,the molecular motion form of thermal micro-clusters and the particle thermal kinetic energy transfer model were explored in detail.The heat transport model of firefighter uniform as the interface between hightemperature fire scene and low-temperature"fire suit system".From the perspective of thermodynamics,the main factors that affect the heat transfer of fiber entered the fire environment,were discussed.The flame retardant mechanism of firefighting clothing was analyzed from the perspective of combustion and heat transfer,and some basic ideas for building flame retardant systems were proposed preliminarily.The foundation was laid for the further research on the heat transfer mechanism of thermal protective clothing.And the reference for the development and design of thermal protective clothing were provided,from the perspectives of clothing structure,fabric and fiber.
