摘要
使用锥形量热仪研究汽车典型门板材料(聚丙烯蜂窝板填料/包覆层组合件)在15、25、35、45 kW/m^2热辐射功率条件下的点燃时间、热释放速率及热释放总量等特性参数。引入火灾性能指数、火灾增长指数,利用Petrella评价体系分析各组合件的火灾危险性。结果表明,PP-PVC较难被点燃,具有高火灾性能指数和低火灾增长指数,PP-PVC组合件火灾危险性较低。
The cone calorimeter was used to study the ignition time,heat release rate and total heat release of the typical car door materials(Polypropylene honeycomb board packing/cladding as⁃sembly)under different heat fluxes of 15,25,35,45 kW/m^2.By introducing fire performance index(FPI)and fire growth index(FGI),using Petrella evaluation system,the fire hazard of assem⁃blies was compared and analyzed.The results showed that the PPPVC is difficult to be ignited,with high fire performance index and low fire growth index,so the PP-PVC assembly has lower fire hazard.
