Abstract

Abstract:

The smoke inhibiting property of FRW, a new fire retardant for wood, was systematically studid by cone calorimeter and Dricon fire retardant was used for comparison. Th results showed that ,at a heat reflux of 50 kW·m^-2, the values of Smoke Ratio(SR),Specific Extinction Area (SEA), the concentration of carbon dioxide (CO₂) and the yield of carbon dioxide (Y_CO₂) of FRW treated wood decreased more considerable than the untreated wood. The FRW treatment of wood had a minor influence on the generation of carbon monoxide. Both FRW and Dricon had strong smoke inhibiting effect on wood and their efficiency were similar.

Key words: Wood, Fire retardant, Smoke inhibition, Cone calorimeter, FRW
