中文摘要：

利用热重和锥形量热仪研究硼酸、硼砂两种典型硼化合物对毛竹热降解和燃烧性能的影响。结果表明：硼酸、硼砂能降低竹材的最大热解速率，缩短高温热解区间，促进残炭生成。与未处理材相比，硼酸、硼砂明显减少竹材燃烧过程中的热量释放，热释放速率降至未处理材的50%左右，总热释放量的降幅分别达50.6%、44.1%。硼酸、硼砂也能抑制竹材燃烧时的烟释放，总烟释放量分别下降95.3%、91.6%。硼酸、硼砂处理竹材能发挥高效的阻燃抑烟功效。

英文摘要：

The combustion and thermal degradation of moso bamboo （Phyllostachys Pubes-cens） treated by boric acid and borax respectively,were characterized by thermogravimetry and the cone calorimeter. Results showed that,these two typical compounds had positive effects on decreasing the maximum pyrolysis rate,narrowing high-temperature decomposition,and pro-moting the yield of residual char when moso bamboo subjected to thermal decomposition. The＆amp;nbsp;treated bamboo exhibited less heat and smoke release compared to the control. Total heat re-lease for borax and boric treated bamboo decreased by 50.6%and 44.1%,respectively. While, the total smoke release decreased by 95.3%and 91.6%,respectively. Applications of boric ac-id and borax have significant influence on protecting bamboo substrate from thermal degrada-tion and combustion.
