AN INVESTIGATION ON COMBUSTIBILITY OF WOOD TREATED WITH FLAME RETARDANTS BY CONE CALORIMETRY

摘要

Wood was treated with guanyl urea phosphate (GUP) and boric acid to impart flame retardance. The combustibility of these samples was evaluated by cone calorimeter. The flammability parameters, including rate of heat release (RHR), total heat release (THR), effective heat of combustion (EHC), total mass loss (TML) and mass loss rate (MLR), yield of CO, smoke production rate (SPR) and specific extinction area (SEA) were recorded simultaneously. By analyzing these data, it was concluded that most combustion parameters of wood were decreased by the treatment. However, gas and smoke release were increased in some degree, especially for the wood treated with boric acid.
