摘要
以木垛火为火源开展全尺寸实体火灾试验,验证新型保护玻璃用喷头的可靠性及应用效果。玻璃试件为钢化玻璃和防火玻璃,厚度均为12 mm。在玻璃的受火面、背火面不同高度处设置热电偶,测量温度变化。研究结果表明,该喷头布水均匀,保证了玻璃防火分隔良好的完整性和隔热性。
The wood crib fire was used to carry out the full scale practical fire experiment to evaluate the safe reliability and ap plication effect of a novel sprinkler for protecting glasses. The fire glass and toughened glass which thickness was 12 mm were used in the experiment. The thermal couples were set at differ- ent height on the fire side and unexposed side of glass to test the change of temperature. The resuhs showed that, the nozzle can ensure the uniformity of water distribution on the surfaee of glasses, and the integrity and insulation performance of glass.
