为了研究竹地板的燃烧特性，以锥形量热仪为研究手段，对本色和炭化胶合竹地板、本色和炭化重竹地板这4种竹地板的燃烧特性进行了对比研究。结果表明，与本色胶合竹地板相比，炭化胶合竹地板的点燃时间提前了3,s；热释放速率、有效燃烧热、总热释放量和质量损失速率的峰值到达时间均提前了2,min，热释放速率、有效燃烧热和质量损失速率的峰值均上升，总热释放量的峰值下降；最终成炭率有所提高。与本色重竹地板相比，炭化重竹地板的点燃时间没有变化；热释放速率、有效燃烧热、总热释放量和质量损失速率的峰值到达时间没有变化，但是峰值均有所下降；最终成炭率有所提高。炭化胶合竹地板的阻燃性能弱于本色胶合竹地板，炭化重竹地板的阻燃性能优于本色重竹地板；总体上，重竹地板的阻燃效果优于胶合竹地板。
Comparative Analysis of Combustion Characteristic of Nature Bamboo Floorings and Carbonized Bamboo Floorings
The aim of this research was to analyze the combustion characteristic of bamboo floorings.Experiments on nature flat pressed bamboo flooring,carbonized flat pressed bamboo flooring,nature strand woven bamboo flooring and carbonized strand woven bamboo flooring were performed by using a cone calorimeter.The results show that,compared with nature flat pressed bamboo flooring,time to ignition(TTI)of carbonized flat pressed bamboo flooring is 3,s earlier.The time to the peak of the rate of heat release(RHR),the effective heat of combus-tion(EHC),the total heat release(THR)and the mass loss rate(MLR)of carbonized flat pressed bamboo flooring is all 2,min earlier.The peak of RHR,EHC,MLR of carbonized flat pressed bamboo flooring is all increased while that of THR is decreased.The final char yield is increased.Compared with nature strand woven bamboo flooring, the time to the peak of RHR,EHC,THR and MLR of carbonized strand woven bamboo flooring shows no change, and the peak of RHR,EHC,THR and MLR is all decreased.The final char yield of bamboo flooring is in-creased.The flame retardation of nature bamboo flooring is better than that of carbonized flat pressed bamboo floor-ing but worse than that of carbonized strand woven bamboo flooring.The flame retardation of strand woven bamboo is better than that of flat pressed bamboo flooring.
