일부 목재와 플라스틱류의 연소 시 연기 위험성 등급 예측 = Prediction of Smoke Risk Ratings in the Combustion of Some Wood and Plastics

국문 초록 (Abstract)

연구에서는 잣나무(pinus koraiensis, nut pine)와 갈참나무(quercus aliena, white oak) 그리고 폴리에틸렌(polyethylene,PE)과 폴리메타크릴산메틸(polymethyl methacrylate, PMMA)를 선정하여 ISO 5660-1의 기준에 따라 콘칼로리미터(conecalorimeter)를 이용하여 측정하였다. 측정된 값으로 Chung’s equations 1 (연기성능지수, SPI), Chung’s equations 2 (연기성장지수, SGI)에 의한 연기 위험성을 예측하고자 하였고, 이를 확장하여 화재 시 연기 위험성 평가를 표준화하기 위하여 기준물질(PMMA)을 사용하여 Chung s equations-V (연기성능지수-V, SPI-V와 연기성장지수-V, SGI-V)와 Chung sequation-VI (연기위험성지수-VI, SRI-VI)에 의한 연기 위험성을 등급화하여 평가하였다. SPI-V는 nut pine 0.73으로 가장낮았고, PE가 37.22로 가장 높았다. SGI-V에서도 PE가 0.03으로 가장 적게 나타나 연기가 가장 적게 발생하는 물질이고,nut pine이 10.00으로 가장 높게 나타나 다량의 연기가 발생하는 것으로 예측된다. SRI-VI는 PE (0.00) < PMMA (1.00)< white oak (1.44) << nut pine (13.70)의 순서로 나타났다. 따라서 PE의 연기 위험성이 가장 낮고, nut pine의 연기 위험성이 가장 높은 것으로 판단하였다. 또한 목재의 연소가 플라스틱류보다 불완전한 형태로 이루어짐을 알 수 있었다.

다국어 초록 (Multilingual Abstract)

In this study, pinus koraiensis (nut pine) and quercus aliena (white oak) and polyethylene (PE) and polymethylmethacrylate (PMMA) were selected. And it was measured with a cone calorimeter in accordance with ISO 5660-1. Withthe measured values, it was intended to comprehensively predict the risk of smoke by Chung’s equations 1 (smokeperformance index, SPI) and Chung’s equations 2 (smoke growth index, SGI). To standardize fire hazard assessment in caseof fire by extending this, standard materials (PMMA) were used to classify the smoke risk by the Chung s equations-V(smoke performance index-V, SPI-V and smoke growth index-V, SGI-V) and Chung s equation-VI (smoke risk index-VI,SRI-VI) to evaluate it. The SPI-V was the lowest with nut pine of 0.73 and the highest PE was the highest with 37.22. In the SGI-V, PE was the material that produced the least smoke with the least amount of 0.03. Nut pine is expected togenerate a large amount of smoke with the highest at 10.00. SRI-VI, it appeared in the order of PE (0.00) < PMMA (1.00)< white oak (1.44) << nut pine (13.70). Therefore, it was judged that PE had the lowest smoke risk and nut pine had thehighest. In addition, it was found that the combustion of wood was done in an incomplete form than that of plastics.
