毛白杨压缩变形回复工艺与应用的研究
A Study on the Technique and Application of Compressive Deformation Recovery of Poplar Timber
摘要
Abstract
In this study,timbers of poplar (Populus tomentosa)were softened by hot water immersion or microwave assisted water immersion,and then compressed cross the grain at the temperatures of 120℃,140℃ and 160℃.Effects of softening and hot pressing temperature on the recovery of wood were analyzed.The process parameters of full recovery of compression deformation based on the viscoelasticity of wood were studied.The results showed that the optimization of process parameters were the poplar wood treated by using 80 kW microwave power 30 s after 12 h water immersion,and compressed at 140℃.The cold water immersion 10 h recovery rate of the wood could reach 80.26%.The application in crafts making confirmed that this technique was feasible.The results of this study would provide a new way to increase the added value of low quality and fast growing wood.关键词
