摘要

本篇研究是採用台灣雲杉、美國雲杉、蘇聯雲杉、鐵杉、美國鐵杉、相思樹、木荷、橡膠木等八種省產與進口樹材進行乙醯化，測定其受褐腐、白腐菌腐朽後之抗腐朽性能。在經過120天白腐菌試驗後，八種乙醯化材之重量保存率皆高於92%，比未處理材之重量保存率56－85%高；其縱向抗壓強度保存率亦高於84%，比未處理材僅保存的29－77%為高。而在120天褐腐菌試驗後，八種乙醯化材之重量保存率皆高於89%，比未處理材之重量保存率43－85%高；縱向抗壓強度保存率皆高於73%，比未處理材僅保存5－22%高出甚多，尤其針葉樹材更加明顯。

Eight wood species were used for this experiment: Taiwan spruce, white spruce (USA), Elka spruce (USSR), Taiwan hemlock, western hemlock, Taiwan acacia, Chinese guger-tree, and rubber wood, to determine the decay resistances of the brown and white-rot fungi of acetylated wood. The decay resistance of eight species of acetylated woods related to residual weight properties was 92%, while the untreated woods was ranging 56-85% only for 120 days white-rot fungi test. The residual compressive strength parallal to grain of acetylated woods was more than 84%, while the untreated woods was ranging 29-77% only. The residual weight of eight acetylated woods was more than 89%, while the untreated woods was ranging 43-85% only for 120 days brown-rot fungi test. The residual compressive strength parallel to grain of acetylated woods was more than 73%, while the untreated woods was ranging 5-22% only, particularly softwoods was very conspicuous in this test.
