聚乙二醇处理的木材尺寸稳定性研究

A Experimental Study of the Dimensional Stability of Wood Treated with Polycthylene Glycols

研究了用聚乙二醇(PEG)处理马尾松、麻栎和江南桤木三种木材的工艺条件及效果,结果表明,三种处理材经过长时间自然存放,抗干缩率可达80%以上,并且其耐腐性能提高。

This paper deals with the dimensional stability of wood of three species, Pinus massoniana,Ouercus acutissima Carr, and Alnus rabeculosa Hand-Mazz, treated with Polyethylene glycol(PEG). The optimum treatment condition was gained from the experiment. The dimensional sta-bility of wood treated with PEG was satisfactory, after a period of natural storage and the anti-shrink efficiency of treated wood reached than 80% and the decay resistance was also raised.
