摘要: 选取目前市场上常用的11种地板作为研究对象,采用锥形量热仪研究了引燃时间、热释放速率、火灾性能指数、总热释放量、有效燃烧热、CO生成量等燃烧特性参数。试验结果及分析表明:11种地板火灾安全性从高到低依次为:栗木、番龙眼、槐木、柞木、白橡木、榆木、刨花板、中密度纤维板、高密度纤维板、枫桦木、楠竹;试样燃烧为4个阶段:一次猛烈燃烧阶段,一次燃烧衰减阶段,二次猛烈燃烧阶段,二次燃烧衰减阶段;11种试样的有效燃烧热数值较为接近,基本在12 MJ/kg左右,且在试验过程中的CO生成量稳定在17×10-6左右。

Abstract: In this paper, 11 kinds of commonly used floor are selected as the research objects. The ignition time, heat release rate, fire performance index, total heat release, effective heat of combustion and carbon monoxide generation were studied by using the cone calorimeter. The floor whose fire safety rated from high to low are chestnut, Pometia spp, scholartree, xylosma, white oak, elm, chipboard, medium density fiberboard, high density fiberboard, maple and phyllostachys pubescens. The combustion of the sample can be divided into 4 stages and they are first violent combustion stage, first combustion attenuation stage, second violent combustion stage and second combustion attenuation stage. All samples have similar effective combustion heat and carbon monoxide generation and they are 12 MJ/kg and 17×10-6.

Key words: cone calorimeter, floor, heat release rate, effective combustion heat, carbon monoxide generation
