建筑保温光伏构件对火反应安全性能

Study on reaction to fire of the insulation photovoltaic building components

介绍建筑保温光伏构件产品的发展、特征及工作方式。以某种典型建筑保温光伏构件一体化产品进行了对火反应性能试验,研究其热释放规律以及与普通有机保温板材燃烧热释放过程的差异化特征,总结了研究对象的优势。燃烧试验过程中试样主体结构保持完整,未发生大面积垮塌和材料脱落。炭化部位纵深已经覆盖聚氨酯层全部厚度。指出采用传统试验手段评估此类具有特殊工作模式建筑制品火灾安全性能的局限性,提出建筑保温光伏构件火灾安全性能的评价应考虑带电工作状态下的燃烧试验。

The development, characteristics and working method of insulation photovoltaic components were introduced. The fire reaction experiment of a integrate component of insulation pho- tovoltaic on building was carried out to analyze the difference of heat release process from the normal organic insulation board. Based on this comparison result, the advantages of this compo- nent were summarized. The main structure of the sample main-tained and there were no extensive collapse and fall off during the experiment. The carbonization in local field was as thick as the sample. The test limitation of this kind of components with special working mode using traditional evaluation methods was pointed out; the suggestion on combustion test with live line in the evaluation of insulation photovoltaic building components was put forward.
