水幕防火分隔的试验研究

Experimental study on water-curtain fireproofing

对大型水幕进行了防火分隔效果的试验研究,证明水幕能有效阻止火灾蔓延,降温隔热效果明显;试验验证了水幕防火分隔的可行性和有效性,影响水幕防火分隔效果的主要因素是水幕用水量、厚度以及水幕水滴的直径,所得的结果对水幕防火分隔设计具有参考作用.

The experimentation is done to validate the performance of big water curtain fireproofing. The result shows thatthewater curtain can stop fire from spreading and make a drop in temperature clearly. The experimentationshows that the water curtain fireproofing is feasible and effective, and the water flux, thickness of the water curtain and the diameter of drip have major influence upon the effect of the water curtain fireproofing. The conclusion of this paper is helpful tothe fireproofing design of water curtain.
