摘要

本報告依CNS 3000白塞法(Bethell-process)，以銅烷基銨化合物(ACQ-1, Alkaline Copper Quaternary-type 1)與微米化銅烷基銨化合物(MCQ, Micronized Alkaline Copper Quaternary)防腐劑，針對不同含水率（17-18%與40-50%）、木材長度（100cm與200cm）、滾輪加壓與無滾輪加壓處理等之柳杉製材，在相同真空加壓注入處理條件下進行防腐處理，並探討對ACQ-1與MCQ防腐劑液注入量與防腐劑有效成分吸收量之影響。試驗結果顯示，低含水率柳杉（材長100cm）滾輪壓縮與無滾輪壓縮處理材對MCQ防腐劑吸收量各會較ACQ-1防腐劑大1.66倍與6.55倍，而高含水率柳杉（材長200cm）則相反，對ACQ-1吸收量各會較MCQ大57.5%與6.1%。
對ACQ-1之吸收量係以高含水率柳杉會大於低含水率柳杉，但對MCQ之吸收量則相反，低含水率柳杉會高於高含水率柳杉。低含水率與高含水率柳杉對ACQ-1與MCQ之吸收量均由端部向中央部位減低。
對ACQ-1防腐劑，在低含水率柳杉，由注入量推算之吸收量會較實際吸收量各大0.27倍與2.01倍，而高含水率柳杉則相反，實際吸收量會各較推算吸收量大0.87倍與1.33倍。對MCQ防腐劑、低含水率柳杉之實際吸收量會大於推算吸收量的3.84倍與3.67倍。而高含水率柳杉、滾輪壓縮處理材係推算吸收量會大於實際吸收量0.11倍，而無滾輪壓縮處理材則相反，實際吸收量會大於推算吸收量1.86倍。

The sawn lumbers of Cryptomeria japonica (Japanese cedar) with different moisture contents (17-18% and 40-50%), lengths (100 cm and 200 cm), and Roller-Pressing treatments (so-called OD method), were treated with ACQ (Alkaline Copper Quaternary- type 1) and MCQ (Micronized Alkaline Copper Quaternary) by Bethell-process according to CNS 3000. The relationships between impregnated preservative quantity and retention of active threshold ingredients of Japanese cedar wood were then investigated. The results showed the retentions of MCQ-treated Japanese cedar with lower moisture content and shorter length were 166% higher for the treated wood with OD method and 655% higher for the treated wood without OD method than those of ACQ-treated Japan cedar, respectively. On the contrary, the retentions of ACQ-treated Japanese cedar with higher moisture content and longer length were 57.5% higher for the treated wood with OD method and 6.1% higher for the treated wood without OD method than those of MCQ-treated Japan cedar, respectively. Both ACQ and MCQ methods appeared higher retentions of impregnated preservative in the ends of wood than in the middle part.
The predicted retentions of ACQ-treated Japanese cedar with lower moisture content were 27% higher for the treated wood with OD method and 201% higher for the treated wood without OD method, respectively. On the contrary, the actual retentions showed the opposite results, in which ACQ-treated Japanese cedar with higher moisture content were 87% higher for the treated wood with OD method and 133% higher for the treated wood without OD method, respectively. The actual retentions of MCQ-treated Japanese cedar with lower moisture content, however, were 384% higher for the treated wood with OD method and 367% higher for the treated wood without OD method, respectively. Their predicted retentions of MCQ-treated Japanese cedar with higher moisture content were 11% higher than the actual retentions for the treated wood with OD method, while, the actual retentions were 186% higher than the predicted retentions for the treated wood without OD method.
