초록

화재시 진화와 건물 보호에 이용되는 소화용 폼의 성능을 평가하기 위해 폼의 열적 특성을 실험적으로 연구하였다. 본 논문은 열복사에 노출된 소방용 폼의 소멸에 대한 연구이다. 화재시 노출된 소화용 폼의 특성을 조사하기 위한 간단하고 반복적인 실험이 가능한 실험장치를 제작하였다. 실험장치는 폼 생성장치, 복사열 발생장치, 데이터 획득장치로 구성하였다. 실험을 수행한 결과, 폼 내부 온도는 15℃~20℃까지는 유사한 양상을 보이다가 약 90℃까지 급격히 상승하였다. 시간경과에 따른 폼 내부의 온도 기울기는 비체적이 커짐에 따라 증가하였다. 또한 폼 깊이에 따른 온도 기울기는 폼 비체적이 커짐에 따라 감소하였다.

In order to evaluate the performance of fire-protection foams used to protect structures from heat and fire damages, the thermal characteristics of them are experimentally investigated. This research focuses on the destruction of a fire-fighting foam subjected to heat radiation. A simple repeatable test apparatus for fire-protection foams subjected to fire radiation is developed. It involves a foam generation equipment, a fire source for heat generation, repeatable test procedures, and data acquisition techniques. Results of the experimental procedure indicated that each thermocouple within the foam responded in a similar manner and gradually to a temperature of 115℃~20℃. At this point, each trace generally rises to a temperature of approximately 90℃. The temperature gradient in the foam as time passes increases with increasing the foam expansion ratio. In addition, it is found that the temperature gradient along the foam for depth decreases with increasing the foam expansion ratio.
