聚乙二醇处理木材的研究——Ⅱ.保存古木的试验

<正>本试验对用PEG处理的古船壳板(杉木、松木)进行了物理和化学测定,并以普通杉木和松木作比较。实验证明,PEG几乎可满足古木保存中的全部要求,用PEG处理古木是可行的最有效的方法。从稳定古木尺寸和抗湿的要求来看,以用PEG4,000较好。

A STUDY ON POLYETHYLENE GLYCOL TREATMENT OF WOOD II. A TEST ON PRESERVING ANCIENT WOOD

Physical and chemical determinations were made on the PEG treated wood samples Cunninghamia lanceolata (Lamb.) Hook.) and Pinus massoniana Lamb.] taken from ancient shipwrecks, and they were compared with the untreated wood of the same spieces. Experements showed that PEG may meet almost all the requirements in the preservation of ancient wood. It was concluded that PEG treatment is the most practical and effective way to preserve ancient wood. In view of mains taining anti-shrinkage efficiency and humidity resistance of ancient wood. PEG 4,000 proved to be better.
