摘要:

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50kW·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,二者的抑烟效力相当。

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 (YCO2) 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.
