【摘要】 利用单因素试验方法确定了浓度为10%的FRW-1木材阻燃剂水溶液浸渍2mm厚杨木单板的常压浸渍工艺为:在常温(25℃)下浸渍120min。利用锥形量热仪(CONE)评价了杨木胶合板的燃烧性能,结果表明:在50kW.m-2的热辐射功率下,载药量为8～10%的阻燃胶合板热释放速率峰值(pk-HRR)、总热释放量(THR)、烟释放速率峰值(pk-RSR)、总烟释放量(TSR)都显著降低,成炭率较未阻燃胶合板有所提高,显示出较好的阻燃、抑烟性能。更多还原

【Abstract】 Wood fire-retardant FRW-1 solution at concentration of 10% was used to impregnate poplar veneer of 2mm thickness.Impregnating process by single factor test was that poplar veneer was impregnated for 120min under room temperature(25℃).The combustion properties of poplar plywood were evaluated by cone calorimetry.The results showed as follows: at a calorific radiation of 50kW.m-2,the peak of rate of heat release(pk-HRR),the total heat release(THR),the peak of rate smoke release(pk-RSR) and the total smoke release(TSR) of the fire retardant plywood at which the chemical loading was 8~10% were declined remarkably compared with the untreated plywood.Meanwhile,the char formation yield increased remarkably compared with the untreated plywood,the fire retardancy and smoke inhibition were preferable.更多还原
