常用高、低温防护服隔热性能研究

为评价常用类型高、低温防护服的防护性能,本研究应用热平板仪、人工气候室和暖体假人等研究设备,对高低温作业典型工种常用的耐高温防护服和低温防护服的隔热性能进行了研究。研究结果显示,不同类型高、低温防护服的服装面料、服装整体的隔热性表现出一定差异,模拟环境下的着装生理学测试结果也存在不同,防护服的面料、结构和工艺等均影响到其整体隔热性能。防护服装的全面评价通常涉及安全性、工效学特性等多个方面,有必要从服装的舒适性、工效学特性等方面进一步研究,并开展大规模的现场人体穿着实验,从而为高低温防护服的选用和设计改进等提供依据。

Heat-Insulation Property Evaluation of thermal protective clothing and cold protective clothing usually used at workplaces

In order to elucidate heat-insulation property of thermal protective clothing and cold protective clothing usually used at typical workplaces existing heat stress or cold stress,heat resistance for tested clothes and their materials were determined with thermal plane-table and thermal manikin,physiological index changes for six healthy males wearing tested clothes in artificial climate cabin were also determined.The results suggest that there is significant difference in heat insulate property for different type thermal protective clothing and cold protective clothing,as well as physiological index of the six healthy males such as temperature under clothes and average skin temperature.Factors affecting heat insulation property include the material,design and concrete technology of tested protective clothing.Thus,to provide scientific data for selection and improving of tested protective clothing,further studies are needed to make comprehensive evaluation for these tested clothes,such as assessment on ergonomics and comfort of tested clothes,and so on.
