摘要：

为了研究电加热手套在极端寒冷环境下抵御寒冷的功能,研制了以金属纤维线和碳纳米管薄膜为加热材料并能抵抗极端寒冷的电热防护手套。采用红外热像仪对电热防护手套进行电热升温实验;并在-30 ℃的极端寒冷环境中进行螺丝螺母装配作业的人体工效实验,并记录人体主观热感受和疼痛感受。结果表明:金属纤维线电热防护手套和碳纳米管薄膜电热防护手套均具有良好的加热性能,在室温环境60 s能够加热至设计最高温度;在-30 ℃的极端寒冷环境下,2种电热防护手套均能在规定时间内增加螺丝螺母的装配数量,即工效提高;综合热感受和疼痛感受的主观评价,电热防护手套抵御寒冷的作用是显著的。

Abstract:

In order to study the function of electrically heated gloves in extremely cold environments, electric-heating protective gloves were developed for resisting extreme cold. The electric-heating material was fabricated with metal fiber and carbon nanotube film. Infrared thermal imaging camera was used to conduct experiments of the electric-heating protective gloves, and a human ergonomic experiment was carried out through screw-and-nut assembly operations in an extremely cold environment of -30 ℃. At the same time, the subjective evaluation of heat and pain was recorded. The results show that electric-heating protective gloves made from both metal fiber and carbon nanotube film demonstrate good heating performance, and can both be heated up to the highest designed temperature in 60 s at room temperature. In the extremely cold environment of -30 ℃, both electric-heating protective gloves can increase the number of screws to be screwed within the specified time, indicating work efficiency improvement. Based on the subjective evaluation of heat and pain, electric-heating protective gloves have a significant effect on resisting cold.

Key words: electric-heating protective glove, metal fiber, carbon nanotube film, ergonomic experiment, thermal imaging experiment
