以经过热磨后的杨木纤维为原料,采用出板前保压降温工艺压制无胶纤维板材。通过对不同热压工艺下压制出厚度为8mm的板材进行力学性能检测与分析,得出了试验范围内热压温度、板坯含水率和热压时间对产品物理力学性能的影响规律。在热压温度190℃、板坯含水率9％、热压时间为l0min的条件下压制出了静曲强度78.6MPa、弹性模量9130MPa、内结合强度1.8MPa、24小时吸水厚度膨胀率5.42％的无胶杨木纤维板。

　　The Binderless fiberboard was obtained by poplar wood fiber hot milled in factory as raw material, without any additives, using the holding pressure cooling process before getting out boards.The effects of hot-pressing temperature, hot-pressing time, mat moisture content on the board's physical.The experiments were obtained the better technical parameters: hot-pressing temperature of 190℃, hot-pressing time of 10min, mat moisture of 9% with the thickness of 8mm and the density of 1.373g/cm3.the MOR, MOE, TS, IB of the bind...
