Prediction of Smoke Risk Ratings in the Combustion of Some Wood and Plastics
In this study, pinus koraiensis (nut pine) and quercus aliena (white oak) and polyethylene (PE) and polymethyl methacrylate (PMMA) were selected. And it was measured with a cone calorimeter in accordance with ISO 5660-1. With the measured values, it was intended to comprehensively predict the risk of smoke by Chung’s equations 1 (smoke performance index, SPI) and Chung’s equations 2 (smoke growth index, SGI). To standardize fire hazard assessment in case of 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 to generate 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 the highest. In addition, it was found that the combustion of wood was done in an incomplete form than that of plastics.
