中文摘要 | 本研究以菇類太空包木質殘料及高密度聚乙烯製備木材塑膠複合材(Wood-plastic composite,WPC),並利用色差計及全反射式傅立葉轉換紅外線光譜評估QUV加速耐候試驗期間,WPC之表面顏色及官能基變化。試驗結果顯示,隨著耐候試驗時間增加,WPC之表面顏色逐漸變淺。而由紅外線光譜可以發現,耐候7天後之WPC,其木質材料特性吸收峰C-O(1031cm^(-1))與羰基(1735cm^(-1))之相對強度呈現增加之趨勢;而隨著耐候試驗時間持續增加,其相對強度則逐漸下降。此外,加速耐候試驗28天後之WPC經粉碎處理後直接回收再製成WPC,並測定其各項物理機械性質,以探討回收再製對WPC性質之影響。其試驗結果顯示,回收再製之WPC,其尺寸安定性與原生WPC間無明顯差異。而在力學性質方面,雖然回收再製之WPC比抗彎強度(Specific modulus of rupture,sMOR)及比抗彎彈性模數(Specific modulus of elasticity,sMOE)略低於原生複合材,但對其比內聚強度(Specific internal bond,sIB)並無明顯影響,且比木螺釘保持力(Specific wood screw holding strength,sWS)較原生複合材高。 |
英文摘要 | In this study, spent mushroom cultivation materials and high density polyethylene were used to manufacture wood-plastic composite (WPC). The spectrophotometer and attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) were employed to evaluate the changes in color and functional groups on the surface of WPC during QUV accelerated weathering. The results demonstrated that the color change of WPC increased with increasing the exposure time of accelerated weathering. Moreover, after accelerated weathering for 7 days, the specific absorption peaks of C-O (1031 cm^(-1)) and carbonyl (1735 cm^(-1)) were significantly increased in ATR-FTIR spectra. However, with increasing the exposure time of accelerated weathering, both relative absorption intensities of 1031 cm-1 and 1735 cm-1 were decreased. After 28 days of QUV accelerated weathering, the WPC was directly smashed and remanufactured into a recycled WPC. Moreover, the effects of recycling and remanufacturing on the physicomechanical properties were also investigated. The results showed that the dimension stability has no significant difference between the recycled and the original WPCs. As for the mechanical properties, the recycled WPC exhibited lower specific modulus of rupture (sMOR) and specific modulus of elasticity (sMOE), similar specific internal bond (sIB), and higher specific wood screw holding strength (sWS) when compared to the original WPC. |
