【摘要】 利用先进的锥型量热计研究了五种常用的高分子装饰材料在暴露于不同辐射热通量（２５ｋＷ／ｍ２，３５ｋＷ／ｍ２和５０ｋＷ／ｍ２）条件下的燃烧性能，以及用氧指数测定仪测量了这些材料的氧指数，并将这两种方法的实验结果进行了对比更多还原

【Abstract】 Reseach has been carried out on the combustion characteristics of five decorating materials, i. e. PVC floor covering, PVC sheet, middle density board, fibre board and polypropylene carpet. Their fire characteristics,such as ignition times and heat release rates have been measured using the Cone Calorimeter. The ignition dada fall a very linear straight line if the plots of t i -1 vs. heat flux have been made. The Cone results and oxygen index values of these materials have been compared.更多还原
