초록

산업분야에서 사용되는 플라스틱 분진은 대부분 가연성이며 화재폭발사고 위험성이 있다. 그러나 산업현장에서 안전한 취급을 위해 활용할 수 있는 폭발특성 자료는 매우 적다. 본 연구에서는 사업장에서 취급하는 다양한 플라스틱 분진 의 폭발특성을 실험적으로 조사하여 관련 자료와 안전정보를 제공하는 것을 목적으로 수행하였다. 이를 위해 20 L 분진폭발시험장치를 사용하여 각종 폭발특성값을 측정하였다. 그 결과 ABS ($209.8{\mu}m$), PE ($81.8{\mu}m$), PBT ($21.3{\mu}m$), MBS ($26.7{\mu}m$) 및 PMMA ($14.3{\mu}m$)시료의 분진폭발지수($K_{st}$)는 각각 62.4, 59.4, 70.3, 303, 203.6[$bar{\cdot}m/s$]의 값이 얻어졌다. 또한 플라스틱 분진폭발에 의한 피해예측을 위하여 분진폭발압력에서 분진의 연소속도가 일정하다고 가정하고 최대압력소요시간 및 화염도달시간을 고려한 화염전파속도모델을 통하여 분진폭발시의 화염전파속도를 추정하였다.

Many of plastic powders handled in industry are combustible and have the hazard of dust fire and explosion accidents. However poor information about the safe handling has been presented in the production works. The aim of this research is investigated experimentally on explosive characteristics of various plastic powders used in industry and to provide additional data with safety informations. The explosibility parameters investigated using standard dust explosibility test equipment of Siwek 20-L explosion chamber. As the results, the dust explosion index ($K_{st}$) of ABS ($209.8{\mu}m$), PE ($81.8{\mu}m$), PBT ($21.3{\mu}m$), MBS ($26.7{\mu}m$) and PMMA ($14.3{\mu}m$) are 62.4, 59.4, 70.3, 303 and 203.6[$bar{\cdot}m/s$], respectively. And flame propagation velocity during plastic dust explosions for prediction of explosive damage was estimated using a flame propagation model based on the time to peak pressure and flame arrival time in dust explosion pressure assuming the constant burning velocity.
