Flammability parameters of wood tested on a cone calorimeter

The effect of different loads of magnesium hydroxide as flame retardant on the flammability parameters of particleboard was studied. The effect of different flame retardant combinations was also compared. The flammability parameters were measured on a cone calorimeter at the uniform external irradiance of 50 kW m(-2) for all modifications. The magnesium hydroxide improved the flammability parameters of particleboard and did not have negative effect on carbon monoxide production. From the different combinations of flame retardants the best retardant effects were measured for the combination of monoammonium phosphate and boric acid. (C) 2001 Elsevier Science Ltd.
