枫杨和柘树应用于弯曲木的工艺研究

THE RESEARCH OF P. STENOPERA AND C. TRICUSPIDATA ON WOOD BENDING TECHNOLOGY

对枫杨和柘树两种木材的弯曲性能及蒸煮软化工艺的试验结果表明,枫杨的弯曲性能为1/11.6,柘树为1/6.7,均能用于一般曲木件的生产。木材含水率和加热温度对木材的顺纹压缩塑性变形及弹性模量均有显著影响,在相同的蒸煮工艺条件下,柘树比枫杨具有更大的塑性变形和弹性模量。

The bending capacity and the steam softening treatment condition of P. stenoptera and C. tricuspidata are discussed in this paper. It turns out that the bending capacity of P. stenofera and C. trienspidaata is one-eleven point sixth and one-six peint seventh respectively. The wood can be used for common bent wood production. The water content and the temperature of the wood obviously affect its plastic deformation parallel to the grain and its modulus of elasticity. Under the same steaming condition, C. tricnspidata shows a greater plastic deformation and modulus of elasticity than P. atenoptera.
