Abstract:
Wood and wood-based panels would produce a large amount of smoke during the combustion. It has great guiding significance to study its smoke regularity and characteristic for the application and exploitation of correlated smoke inhibition technology. The characteristics of smoke production and the regularity of the change in smoke temperature of Pinus massoniana, Larix gmelinii, Cunninghamia lanceolata(Lamb.)Hook, Paulownia, Populus, plywood and medium density fiberboard(MDF)were studied with a cone calorimeter(CONE). Effect of the irradiance intensity on smoke production and temperature was also discussed. The results showed that the smoke emission process and temperature of wood and wood-based panels changed similarly, i.e., “strong-weak-strong-weak”. The variation of smoke production and temperature was corresponding to the mass lose rate, namely, the smoke production and temperature increased with the mass lose rate increasing. The total smoke production of MDF was the highest followed by softwood, hardwood and plywood. The smoke production and temperature increased and the second peaks appeared earlier with the irradiance intensity increasing.
