复合保温风管的燃烧性能研究
Research on combustion performance of composite insulating air ducts
摘要：
针对目前市场上几种常见的新型复合保温风管，采用我国现行的燃烧性能分级试验、欧洲最新燃烧分级试验和实体火灾试验三种方法进行了燃烧性能研究，全面、客观地分析了复合风管材料的燃烧特性，并结合我国防火设计规范等相关标准对风管的规定，提出了在建筑物中使用GB 8624规定的难燃B1级风管的可行性和安全性建议。
Abstract：
Studies the combustion performance of several kinds of new composite insulating air ducts in present markets by adopting three methods, i.e. the current combustibility classification testing according to China’s regulation, the newly-revised European fire classification testing and the simulating actual fire testing. Comprehensively and objectively analyses the combustion characteristics of composite air duct materials. Combined with the rules in correlation standards such as the fire protection design code, proposes some suggestions of feasibility and security for using the B1 level air duct in the standard of GB 8624 in buildings.
