【摘要】：选取装饰装修材料—PVC壁纸、丙纶地毯和EPS保温板,采用SCY-1型建筑材料烟密度测定仪测量其燃烧过程中烟密度的变化。材料的加工尺寸为(25.4±0.3)mm×(25.4±0.3)mm×(6.2±0.3)mm。采用8层PVC壁纸叠加,使其厚度满足尺寸要求。在材料中加入不同量的水浸泡,进行对比试验,研究水对材料烟密度的影响。结果表明,加水后,3种材料开始产烟的时间均比干材料开始产烟的时间延迟。PVC壁纸和EPS保温板总产烟量、烟密度等级(SDR)随加水量的增多而减小。丙纶地毯总产烟量、烟密度等级(SDR)随加水量的增多先增大后又减小。3种材料中,PVC壁纸的最大烟密度、总产烟量和烟密度等级最大。
[Abstract]:PVC wallpaper, polypropylene carpet and EPS insulation board were selected to measure the smoke density during combustion with SCY-1 type building material smoke density meter.The machining size of the material is 25.4 卤0.3)mm 脳 mt25.4 卤0.3)mm 脳 0.3mm.Eight layers of PVC wallpaper are used to make the thickness meet the requirement of size.The effect of water on the smoke density of the material was studied by adding different amount of water into the material.The results showed that after adding water, the time of smoke production of the three kinds of materials was more delayed than that of dry materials. The total smoke production of PVC wallpaper and EPS insulation board decreased with the increase of water content.The total smoke production and smoke density grade (SDR) of polypropylene carpet increased first and then decreased with the increase of water content, and then decreased the maximum smoke density of PVC wallpaper in 3 kinds of materials, and the total smoke yield and smoke density grade were the largest.
