【摘要】：利用不同火源对20种西藏古建筑中典型装饰织物和4种纯涤、纯棉和涤棉织物进行了燃烧试验,研究了其燃烧行为;利用极限氧指数(limiting oxygen index,LOI)和垂直燃烧(vertical burning,VB)方法对这20种织物的燃烧性能进行了测试,判定了燃烧级别,分析了材质的影响,并对4种纯涤、纯棉和涤棉织物分别在拉萨和合肥同期进行了LOI和VB对比测试,探讨西藏高原环境对装饰织物燃烧性能的影响;利用锥形量热标准化测试研究了部分代表性织物的对火反应特性,分析了材质、厚度等织物属性的影响.结果表明,西藏古建筑内大部分装饰织物为易燃可燃物(LOI≤20),材质以丝质天然纤维和纤维素
[Abstract]:The combustion behavior of 20 typical decorative fabrics and 4 pure polyester, pure cotton and polyester cotton fabrics in 20 kinds of ancient buildings in Tibet were studied by using different fire sources. The combustion properties of the 20 fabrics were tested by (limiting oxygen index loi and vertical burning VB, the combustion grade was determined, the influence of the material was analyzed, and four kinds of pure polyester were studied. The LOI and VB tests of pure cotton and polyester cotton fabrics were carried out in Lhasa and Hefei at the same time, respectively, to explore the effect of environment on the burning properties of decorative fabrics in Tibet Plateau. The fire response of some representative fabrics was studied by means of conical calorimetry, and the effects of material and thickness on the properties of fabrics were analyzed. The results show that most of the decorative fabrics in ancient buildings in Tibet are flammable combustible (LOI 鈮，
