摘要: 采用杨木化机浆污泥与马尾松纤维复合制得污泥/纤维复合纤维板,分析污泥添加量、脲醛树脂施加量和热压温度对复合 板物理力学性能的影响,并用锥形量热仪分析复合纤维板的燃烧性能。结果表明:随着污泥加入量的增加,污泥/纤维复合板的 内结合强度增加,但静曲强度和弹性模量则呈下降趋势。当污泥用量达到15%、施胶量为8%、热压温度为165 ℃时,污泥/纤维 复合板的各项力学性能均能达到GB/T 11718—1999中密度纤维板国家标准要求。加入15%污泥的纤维板的热释放速率及质量损 失速率均降低,可明显降低火灾的危险性。

Abstract: A new type of fibreboard was manufactured by using the sludge recovered from alkaline hydrogen peroxide machine pulp(APMP)of poplar and Pinus massoniana fiber as the starting materials in this paper. Effects of the ratio of sludge dosage, UF resin content, and hot-press temperature on the mechanical properties of the sludge-fiber boards were investigated. Result showed that higher content of sludge resulted in higher IB, lower MOR and MOE. A sludge-fiber board could be produced MDF used for interior with 15% content of sludge, according with request of the Chinese national standard GB/T 11718—1999. The fiber board with 15% sludge could reduce the danger of the fire, the heat release rate and the mass loss rate of the board.
