연소온도 조건에 따른 FRP 및 시트커버 내장재의 연소가스 발생량 비교

초록

We have evaluated the toxicity of interior materials for the railway passenger car by checking the release of CO2, CO, NOx, SO2, HCl, HF, HBr, HCN. The NOx is one of the most effective for the determination of Toxic Index R value. It is generally known that the mechanism of thermal NOx generation without the Interior Material nitrogen source. This study started from the idea to check the NOx difference according to the furnace temperature. But from the results, it was revealed that NOx is not so sensitive for the furnace temperature in case of solid burning. Other gases such as HCN, CO were more changeable to the furnace Temp. We reported the test result as for toxicity index r(x).
