요약
외부복사 열원(20, 25, 35, 50, $70kW/m^2$)과 산소/질소의 혼합가스의 농도 변화에 따른 페놀폼의 연소 특성을 분석하였다. 산소지수는 KS M ISO 4589-2를 만족하는 산소지수시험기를 사용하였으며, 점화시간, 임계열속, 그리고 질량감소속도는 ISO 5660-1를 만족하는 mass loss calorimeter를 사용하여 측정하였다. 연구결과, 외부 복사열원에서 임계열유속은 $28.99kW/m^2$, 평균질량감소속도는 $0.56{sim}1.77g/m^2s$로 측정되었으며, 한계산소지수는 45.1%를 나타내었다. 모든 연구결과를 종합한 결과 페놀 폼이 다른 발포 물질에 비해 아주 우수한 화재안정성을 나타낸다는 것을 알 수 있었다.
Abstract
The combustion characteristics of phenol foam were analysed using variable external irradiation level (20, 25, 35, 50, and $70kW/m^2$) and in the mixture gas of oxygen/nitrogen. The oxygen index were carried out from the oxygen index tester (KS M ISO 4589-2) and ignition time, critical heat flux, and mass loss rate were carried out from the mass loss calorimeter (ISO 5660-1). As the results of this study, the critical heat flux and average mass loss rate were $28.99kW/m^2$ and $0.56{sim}1.77g/m^2s$ respectively at the variable external irradiation level. And the limited oxygen index were 45.1% in mixture gas of oxygen/nitrogen. In conclusion, we knew that phenol foam had the best performance than other foam materials in fire safety from all data of this study.
Key Words: Phenol foam, Critical heat flux, Ignition time, Mass loss rate, Limited oxygen index
