The yield from aspen timber is best when relatively short components of sawn wood can be utilized. 当短的锯木部件可被利用时,白杨可以达到最佳产量。
A kind of wood-plastic composites was prepared by vacuum impregnation method with in-situ compounded nano-SiO2 modified urea-formaldehyde and aspen wood. 以原位复合纳米SiO2改性脲醛树脂为填充体,人工速生杨木为基体,通过真空加压浸渍法制得木塑复合材料。
Whether triploid Chinese poplar or Zhonglin aspen, physics properties of five-year-old wood are better than that of three-year-old wood. 使用三毛杨和中林杨的混合杨木制备APMP,物理性能基本不随二者比例的变化产生大的波动。
