The purpose of this study was to provide insights into deeper understanding of the combustion performance of cement-bonded particleboards. Cement-bonded particleboard produced from Chinese fir processing residues is fabricated and its combustion performance is further evaluated by cone calorimeter analysis. Obtained results revealed that combustion performance of cement-bonded particleboard positively depends on the density of which, and higher density imparts corresponding particleboards reduction in heat release rate, total heat release, and mass loss rate, along with elevated time to ignition. With the density of particleboard increasing from 0.7 to 1.0 g/cm3, peak and average heat release rate, total heat release and average mass loss rate of specimens were decreased by 55.9, 73.4, 77.8 and 60.3%, respectively. Furthermore, time to ignition of particleboard increased by more than 20 times as the density increasing. Residual mass of specimens was also remarkably elevated along with higher yields of CO and CO2 as the density of particleboard increasing. We believe that proposed investigation is beneficial for the value-added utilization of wood processing residues and further developing products fabricated by wood processing residues.

密度对木材加工残渣胶结刨花板燃烧性能影响的探讨

本研究的目的是深入了解水泥粘合刨花板的燃烧性能。以杉木加工残渣为原料制备水泥结合刨花板,并通过锥形量热仪分析进一步评估其燃烧性能。获得的结果表明,水泥结合刨花板的燃烧性能正取决于密度,密度越高,刨花板的放热率、总放热率和质量损失率相应降低,同时点火时间延长。随着刨花板的密度从0.7增加到1.0 g/cm 3, 试样的峰值和平均放热率、总放热率和平均质量损失率分别下降了 55.9、73.4、77.8 和 60.3%。此外,随着密度的增加,刨花板的点火时间增加了 20 多倍。随着刨花板密度的增加,试样的残余质量也显着增加,同时 CO 和 CO 2 的产量更高。我们认为,拟议的调查有利于木材加工残留物的增值利用和进一步开发木材加工残留物制造的产品。
