Chinese Abstract

本試驗目的在於評估木材經磷胺化合物處理後之尺寸安定性。木材係以五氧化二磷分別與十二種有機胺在二甲基甲醯胺中反應,反應後木材再以浸水法測定其抗收縮能;平衡含水率與體積膨脹率變化情形,係將處理材放置於27℃與30% RH、27℃與65%RH、27℃與90% RH的環境中21天測試。試驗結果顯示:磷胺化合物處理材的抗收縮能數值較低:其平衡含水率與體積膨脹變化率則隨著相對濕度的增加而變大,尺寸安定性較乙醯化、環氧化、與異氰酸鹽化處理材差:磷胺化合物無法有效地改善木材的尺寸安定性。

English Abstract

To evaluate the dimensional stability of phosphoramide-reacted wood, wood was reacted with a mixture which was derived from compounding phosphorus pentoxide and each of 12 amines including alkyl, halophenyl, and phenyl amines in N,N-dimethylformamide. Dimensional stability of such reacted wood was analyzed by antishrink efficiency (ASE) using the water-soak method. Volumetric swelling and equilibrium moisture content (EMC) of phosphoramide-reacted woods were also determined after being maintained at 27℃ and 30% RH, 27℃ and 65% RH, and 27℃ and 90% RH for 21d. The results revealed that phosphoramide-reacted woods had lower antishrink efficiency values than those of acetylated wood, expoxided wood, and isocyanated wood. Volumetric swelling and equilibrium moisture content of phosphoramide-reacted wood were increased when exposed to an environment with a higher relative humidity. Phosphoramides had less effect on improving the dimensional stability of wood.
