摘要
采用硫酰氟作为熏蒸剂处理樟子松木材,在试验室条件下,研究熏蒸处理对木材的抗弯强度、抗弯弹性模量、顺纹抗剪强度和顺纹抗压强度的影响。结果表明,经硫酰氟熏蒸处理后樟子松木材的抗弯强度、抗弯弹性模量、顺纹抗剪强度和顺纹抗压强度均有程度不同的变化;除顺纹抗剪强度有所增强,抗弯强度、抗弯弹性模量和顺纹抗压强度均减小;抗弯强度和抗弯弹性模量的相关性有所下降。
The effect on fumigation treatment bending strength, modulus of elasticity, sheafing strength parallel to grain and compressive strength parallel to grain of wood were studied. The result showed that all them had different changes. Bending strength, modulus of elasticity, and compressive strength parallel to grain of wood increased beside sheafing strength parallel to grain descended. The correlation between bending strength and modulus of elasticity descended to some extent.
