对典型壁面装饰材料胶合板在水雾的作用下的火灾特性进行了研究.理论分析了水雾对火焰从控火作用到灭火作用的转变,以及影响控火作用的临界水雾施加量的因素.通过在ISO9705燃烧室内开展全尺寸实验研究了不同水雾流量对竖直火蔓延的控制效果的影响,并得到了水雾施加在火焰预热区时临界水雾施加率的大小.
The fire performance of Plywood lining material extinguishing by water spray was analyzed. The function of water spray from fire control to fire extinguishment and critical rate of water application on control fire were analyzed. The influence that water sprayed in various rate of water application on vertical fire spread were discussed by full-scale fire tests which conducted in the ISO 9705 room and the critical rate of water application on warm-up area was gained.
