摘要
采用加热和水蒸气处理方法对人工林杨树木材进行压缩变形恢复率的研究,目的是为了改善人工林软质木材的材性,提高其尺寸稳定性。结果表明:加热和水蒸气处理都是固定人工林木材压缩变形的有效方法;在处理温度相同时,水蒸气处理方法只需要4 min或8 min,而高温加热处理需要10 h或20 h。水蒸气处理方法更加经济。
The study of compressed deformation recovery rate by heating and steaming treatments on poplar wood(cut from plantation),is to improve characteristics of artificial soft wood and increase its size stability.The results showed that: heating and steaming treatments are all effective ways of fixed the timber deformation;At same temperature,steaming treatment needed 4 min or 8 min,only,and heating by high-temperature needed 10 h or 20 h.It concludes that steaming treatment is a more economical way.
