Abstract

Purpose: In order to conduct a spontaneous ignition test in which a fire occurs in the absence of an ignition source due to the oil adsorbed on the towel. A phenomenon in which spontaneous ignition occurs when adsorbed to fibers using flaxseed oil, which is drying oil and olive oil, which is non-drying oil, is tested through an experiment. Method: After placing the sample container in the experimental device, observe the change in the central temperature of the sample, and when the central temperature rises above the set temperature and a fire occurs, it is judged as “ignition”, and the experiment is stopped after checking the maximum value of the central temperature of the sample,When the central temperature of the sample was maintained similar to the set temperature, it was judged as “non-ignition” and the experiment was stopped. Result: In the towels with adsorbed flaxseed oil, the temperature in the sample container increased rapidly and combustion occurred in sheets 5, 10, and 15. Olive oil is a non-drying oil, does not ignite because it is difficult to dry because carbon is a single bond and it is difficult to bond with oxygen. Conclusion: It was confirmed that the more the amount of towel adsorbed to the drying oil, flaxseed oil, the longer the time to reach the set temperature and the occurrence of ignition.

연구목적: 타올에 흡착된 기름에 의하여 점화원이 없는 상태에서 화재가 발생되는 자연발화 실험을 하기 위하여 건성유인 아마인유와 불건성유인 올리브유를 사용하여 섬유에 흡착되었을 때 자연발화가 발생되는 현상을 실험을 통하여 화재가 발생되는 현상을 확인하였다. 연구방법: 시료용기를 실험장치에 넣은 후 시료의 중심온도 변화를 관찰하여 중심온도가 설정온도 보다 상승하고 화재가 발생하였을 때를 ｢발화｣로 판정하여, 시료의 중심온도 최대치를 확인한 후 실험을 중지하였으며, 시료의 중심온도가 설정온도와 유사하게 유지되었을 경우 ｢비발화｣로 판정하고 실험을 중지하였다. 연구결과: 아마인유가 흡착된 타올은 5장, 10장, 15장에서 모두 시료용기 내의 온도가 급상승되고 연소가 발생되었으나, 불건성유인 올리브유는 탄소가 단일결합으로 되어 있어 건조가 어렵고 산소와의 결합이 어렵기 때문에 발화가 되지 않았다. 결론: 건성유인 아마인유가 흡착된 타올의 량이 많을수록 설정온도에 도달되는 시간이 길어지는 현상으로 발화가 발생되는 것을 확인하였다.
