Wood is also an important fuel since ancient times, has a higher combustion heat value, a lower ignition combustion temperature and a faster flame propagation speed, and belongs to combustible materials. Fire is one of the major disasters threatening the safety of human life and property. The building structure must adopt fireproof and flame-retardant materials, the interior decoration of civil buildings and industrial plants actively adopts fireproof materials and flame-retardant materials, and the materials which generate a large amount of dense smoke or toxic gas during combustion are avoided as much as possible. As important building structures and decorative materials, wood and products thereof have high fire hazard due to low ignition and combustion temperature, high heat productivity and high flame propagation speed.
