방호복에 관한 연구-복사열에 의한 방호복의 표면 온도 변화-

Abstract

This study shows the thermal characteristics of the protective clothing exposed to the radiation heat. The surface temperature of the protective clothing exposed to the radiation with the passage of time sharply increased as the exposed-distance became closer. Also as the radiant heat flux increased, the surface temperature is higher and the time reaching steady state in sharply shorter. As the exposed-distance become more distant, the surface temperature of the protective clothing decreased and difference of temperature between the front side and the back side of the clothing decreased as well. Besides, the radiant heat flux increased, the safety exposed-distance increased. Therefore it is necessary that the worker have to work keeping a fixed safe distance from the radiant heat source.
