摘要
以常见地毯为研究对象,以辐射热源法测得的临界辐射通量值为依据,对比不同材质样品在火灾场合下阻燃性能的优劣和燃烧蔓延程度的高低;引入锥形量热仪法,获得样品在同一辐射强度下产生燃烧现象的难易程度,探讨热释放速率,总热释放量等燃烧特性指标,并进行理论分析,获得的试验结果可为建筑防火工程中铺地材料的选择提供参考。
The normal carpets are chosen as the research object. According to the critical radiant flux results of FRP test, the fire resistance and burning spread of different materials were compared. The ignition difficulty level under the same radiation level was researched by Cone Calorimeter. Then the heat re- lease rate and the total heat release were discussed and the tests results could be the guidance for the selection of flooring mate- rials in construction fire protection engineering.
