用CONE法研究木材阻燃剂FRW的抑烟性能

STUDY ON THE SMOKE INHIBITION OF WOOD FIRE RETARDANT FRW BY CONE CALORIMETER

采用锥形量热仪 (CONE)法系统地测定了新型木材阻燃剂FRW的抑烟性能 ,讨论了FRW对木材燃烧时发烟及烟气毒性的影响 ,并与Dricon阻燃剂进行了对比。结果表明 ,当热辐射功率为 5 0kW·m- 2 时 ,FRW阻燃处理木材的烟化率SR、比消光面积SEA、二氧化碳浓度CO2 及二氧化碳产率YCO2 比未处理木材显著降低 ;FRW阻燃处理对木材燃烧时一氧化碳的生成元显著影响 ;FRW与Dricon均具有很强的抑烟作用 。

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 (CO 2) and the yield of carbon dioxide ( Y CO 2 ) 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.
