中文摘要 | 本研究目的在於探討臺灣杉(Taiwania cryptomerioides)邊材經二乙基氯磷酯(diethylchlorophosphate, DECP)化學改良後之耐腐性與抗白蟻性。試材與二乙基氯磷酯於60~65%下反應1、3、5、10、15、20 hrs後之藥劑留存率分別為7.25、15.89、23.73、26.2、29.49、30.76%。磷酯化材之耐腐性測定係依照CNS-6717標準以褐腐菌Laetiporus sulphureus及白腐菌Trametes versicolor進行評估。磷酯化材之抗白蟻性測定係依照ASTM-D3345標準以家白蟻(Coptotermes formosanus)進行評估。試驗結果顯示木材經磷酯化處理可以有效地改善其耐腐性與抗白蟻性。 |
英文摘要 | The objective of this research was to improve fungal decay and termite resistance of Taiwania (Taiwania cryptomerioides) sap wood chemically modified with diethylchlorophosphate (DECP). Specimens were treated with DECP at 60-65℃ for 1-, 3-, 5-, 10-, 15- and 20 hrs, and chemical retention (CR, %) of the reacted wood were 7.25, 15.89, 23.73, 26.2, 29.49 and 30.76%, respectively. Fungal decay resistance of phosphorylated wood was assessed according to procedures described in CNS standard 6717, and brown-rot fungus Laetiporus sulphureus and white-rot fungus Trametes versicolor were applied in this study. Termite resistance of the reacted wood was determined according to ASTM D3345, with test termite Coptotermes formosanus. Results showed that wood biodeterioration caused by decay fungi and termite was effectively prevented by treating wood with DECP through the reaction of phosphorylation. |
