典型木竹地板燃烧特性实验研究

Experimental study on combustion characteristics of typical wood and bamboo flooring

运用辐射引燃仪和TY2000-B型气体检测仪对白蜡木地板、桦木地板、龙凤檀地板和竹地板的燃烧特性进行测试。从表面温度变化、质量损失率、热释放速率和烟气中CO含量4个方面比较4种地板的火灾危险性。实验表明:相同条件下,竹地板的点燃时间最短,着火温度最低,质量损失率、热释放速率、烟气毒性最大。白蜡木地板质量损失率、热释放速率、烟气毒性最小。综合几方面因素,竹地板的火灾危险性最大,白蜡木地板的火灾危险性最小。

Experimental study on combustion characteristics of commonly used ash wood floor, birch floor, eumaru floor and bamboo floor by radiative ignition instrument and TY2000--B type gas detector instrument. The fire risk of the four kinds of floors was compared by the change of surface temperature, mass loss rate, heat release rate and the CO content in the flue gas. Experimental results showed that： under the same condi- tions, the ignition time of bamboo floor is shortest; the ignition temperature of bamboo floor is the lowest. The mass loss rate and heat release rate and smoke toxicity of bamboo floor is lar- gest. The mass loss rate and heat release rate and smoke toxici- ty of ash wood floor is smallest. Integrated four factors, the bamboo floor＇s fire risk is maximum while the ash wood floor is minimum in these four floors.
