PVC壁纸烟密度的试验研究
|
摘要
本文使用SCY-1型建筑材料烟密度测定仪,依据《建筑材料燃烧或分解的烟密度试验方法》(GB/T8627—2007),测定PVC壁纸燃烧过程中烟密度的变化。为了考察水及S-100-AB-DW水系灭火剂对材料产烟量的影响,用水及S-100-AB-DW水系灭火剂浸泡PVC壁纸后,开展了对比试验。结果表明,浸水后,材料开始产烟的时间延迟,浸了S-100-AB-DW水系灭火剂的材料开始产烟时间提前,水及S-100-AB-DW水系灭火剂都对最大烟密度影响不大,都使总产烟量和烟密度等级减小,但水的作用更显著。
In this paper, the smoke density of PVC wallpaper in combustion process were measured by using the building smoke density tester of SCY-1 type according to Test Method for Smoke Density of Burning or Decomposi-tion of Building Materials(GB/T 8627—2007)method. Smoke density after adding water and water-based extin-guisher were compared in order to investigate the effects of water and water-based extinguisher on smoke density ofPVC wallpaper. According to the results,the beginning time of smoke emerge was shortened after adding water whileit was prolonged after adding water-based extinguisher. Both water and water-based extinguisher had little influenceon the maximum smoke density(MSD)of PVC wallpaper. Both water and water-based extinguisher resulted in decreasing of the total production of smoke and smoke density rating(SDR), but the effect of water was significantly.
