燃料用木质锯末坯块冷压成型工艺研究论文摘要:
为了减少对传统能源的依赖,开发可再生能源已成为一项重要的研究方向。木材作为一种天然可再生资源,具有燃烧时生成的二氧化碳与环境中CO2相储存,碳中和效应明显,因而被广泛应用于生活和工业生产中。本研究采用木质锯末为原料,通过冷压成型工艺制备成木质锯末坯块,探究了不同压力、温度、时间对制备木质锯末坯块的影响。结果表明,压力和温度均会显著影响木质锯末坯块的密度、含水率和力学性能。在本研究中,最佳的工艺参数为:压力8MPa,温度120℃,时间60min,得到的木质锯末坯块密度为0.767g/cm³,含水率为5.73%,抗压强度为9.21MPa。该工艺以锯末为原料,通过机械压缩得到木质锯末坯块,不仅增加了锯末的利用率,而且利用这种方法制备的木质锯末坯块还具有较高的力学性能,对于木质燃料的应用具有重要的研究价值。
