摘要

本研究探討三種針狀刺縫處理與ACQ-BKC、CuAz防腐藥劑濃度對柳杉、台灣杉及光蠟樹防腐處理材注入性能之影響，透過試材滲透度與銅化合物有效成分吸收量評估不同濃度處理後之防腐處理材適用的危害分級，研究結果顯示柳杉、台灣杉及光蠟樹之ACQ-BKC與CuAz防腐處理材，可符合K4與K5危害分級要求之80%以上滲透度基準。ACQ-BKC比CuAz防腐藥劑對木材有較良好滲透性。針狀刺縫處理具有提高防腐藥劑滲透性之效果。柳杉、台灣杉及光蠟樹針狀刺縫處理試材欲達到K4與K5等級之ACQ-BKC處理液濃度分別為6.2%與15.4%；7.1%與15.5%；4.2%與12.4%。柳杉、台灣杉及光蠟樹針狀刺縫處理試材欲達到K4與K5等級之CuAz處理液濃度分別為7.4%與12.0%；9.4%與16.3%；5.7%與9.8%。以刺縫密度10,000孔/m^2，深度10mm之針狀刺縫處理具有可有效改善防腐藥劑注入性能，建議產業界可應用本技術改善防腐處理材的品質。

This study investigated three kinds of pin incising treatments and different concentration solutions of ACQ-BKC and CuAz preservatives on the penetration performance of Japanese cedar (Cryptomeria japonica), Taiwania (Taiwania cryptomerioides), and Taiwan ash (Fraxinus griffithii). The hazard classes of the preservative treated wood were evaluated according to the retention of active ingredients (copper compounds) and the penetration of preservatives in the treated specimens. The experimental results showed that the penetrations of preservative treated wood of Japanese cedar, Taiwania, and Taiwan ash could conform K4 and K5 outdoor use class penetration requirements of 80%. The ACQ-BKC preservative was found to have the higher penetration than that of CuAz preservative. The penetration of preservatives could be improved effectively by pin incising treatment. The ACQ-BKC solution concentrations for preservative treated wood could conform K4 and K5 hazard classes of Japanese cedar, Taiwania, and Taiwan ash should be at least of 6.2% and 15.4%; 7.1% and 15.5%; 4.2% and 12.4%, respectively. The CuAz solution concentrations for preservative treated wood could conform K4 and K5 hazard classes of Japanese cedar, Taiwania, and Taiwan ash should be at least of 7.4% and 12.0%；9.4% and 16.3%; 5.7% and 9.8%, respectively. The pin incising treatment with a density of 10,000 holes/m^2 and a depth of 10 mm could effectively improve the penetration performance of wood preservatives. It is suggested that the industry can apply this technology to improve the preservation quality of preservative treated wood.
