Abstract

For the safe handling of styrene, this study was investigated the explosion limits of styrene in the reference data. The flash points and AITs(auto-ignition temperatures) by ignition delay time were experimented. As a results, the lower and upper explosion limits of styrene recommended 0.9 Vol.% and 8.0 Vol.%, respectively. The lower flash points of styrene by using closed-cup tester were experimented $29^{\circ}C{\sim}31^{\circ}C$. The lower flash points of styrene by using open cup tester were experimented $32^{\circ}C{\sim}36^{\circ}C$. This study measured relationship between the AITs and the ignition delay times by using ASTM E659 tester for styrene. The experimental AIT of styrene was $460^{\circ}C$.

스티렌의 안전한 취급을 위해, 폭발한계는 문헌을 통해 고찰하였고, 인화점과 발화지연시간에 의한 발화온도를 측정하였다. 그 결과, 스티렌의 폭발하한계는 0.9 Vol.%, 상한계는 8.0 Vol.%를 추천하고, 밀페식 장치에 의한 스티렌의 하부인화점은 $29^{\circ}C{\sim}31^{\circ}C$로 측정되었으며, 개방식에서는 $32^{\circ}C{\sim}36^{\circ}C$로 측정되었다. ASTM E659 장치를 사용하여 자연발화온도와 발화지연시간을 측정하였고, 스티렌의 최소자연발화온도는 $460^{\circ}C$로 측정되었다.
