Probing the Effects of Density on Combustion Performance of Cement-bonded Particleboard Produced from Wood Processing Residues

Abstract

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.
