요약

가연성 물질의 자연발화는 화재예방을 위한 중요한 인자가 된다. Gasoline과 Cenox의 최저발화온도는 시료량 $100{mu}l$서 각각 $340.5^{circ}C,;368.5^{circ}C$를 구하였다. 또한 순간발화온도는 발화되는 시간이 1.0 sec가 되는 온도인 $416^{circ}C,;427^{circ}C$를 구하였다. 혼합물질에 대한 시료량과 최저발화온도는 Cenox 60 v/v% 이하 첨가시 최저발화온도의 변화는 적게 나타났으나, 80 v/v% 이상에서는 높게 나타났다. 따라서 가솔린 엔진의 연료로 사용시 Gasoline과 Cenox의 혼합비가 대단히 중요한 인자가 될 것으로 사료된다.

Abstract

The spontaneous ignition of a flammable matter is a crucial factor for the prevention of a fire. The minimum ignition temperatures of Gasoline and Cenox in $1000{mu}l$ of a sample were determined to be $340.5^{circ}C;and;368.5^{circ}C$ respectively. In addition when the time taken for ignition was 1.0 sec, the instantaneous ignition temperatures were $416^{circ}C;and;427^{circ}C$ respectively. Moreover, the changes in the minimum ignition temperature were small when less than 60 v/v% of Cenox was added, but the changes were great when 80 v/v% or more was added. Therefore, it is hypothesized that, when used as a fuel in the Gasoline engine, the ratio of the mixture of Cenox and Gasoline will be a very important factor.
