中文摘要 | 為拓展速生樹種小徑木之利用層面,以台灣速生樹種之小徑木相思樹及木油桐為原料,利用瑞典Sunds Defibrator之實驗用解纖機(D型)進行解纖,探討中密度纖維較之製造之最佳製板條件。試驗結果為200 g絕乾木片以180℃蒸氣壓力蒸煮3 min,解纖1 min為最適宜,不僅節省解纖動力且可獲得優良之纖維,其解纖動力總耗電量0.1516-0.1763kwhr,纖維長度0.70-0.82 mm,纖維游離度15~19 Defibrator. Second。按0.75比重,1 cm板厚之製材以木油桐之成板較擾,其板性如下:MOR為(287± 60)kgf/cm^2,MOE為(2.3± 0.3)x10^4 kgf/cm^2,IB(801± 2.7)kgf/cm^2,木螺絲釘保持力(49.5± 6.1)kgf,吸水厚度膨脹率(33.7± 8.2)%,吸水率(86.8± 20.8)%。 |
英文摘要 | The purpose of this study is to increase wide utilization of fast-growing tree species, using smalllogs of Taiwan acacia and Wood oil tree as raw materials whichwere defibered by the Sunds Defibrator's D-type defibrator to investigate the optimum process conditions for producing medium density fiberboard. The result of this experiment is: A batch of wood chip at the oven dry weight of 200g was defibered under 180℃ steam pressure for 1 min. and cooked for 3 min., can have the most excellent fiber. The range of the fiber length was 0.70- 0.82 mm, and Sunds Defibrator freeness was 15-19 Defibrator second. Under this condition the power expense was minimum, its total electric power was 0.1516 ~ 0.1763 Kwhr. The physical properties of medium density fiberboard (1 cm thickness and 0.75 specific gravity) made of Wood oil tree were better than that of Taiwan acacia, and its properties were as follows: MOR was (287 ± 60) kgf/cm^2 , MOE (2.3 ± 0.3) X 10^4 kgf/cm^2, Internal bond strength (8.1 ± 2.7) kgf/cm^2 , Wood screw holding capacity (49.5 ± 6.1) kgf, The thickness swelling was (33.7 ± 8.2)%, Water absorption was (86.8 ± 20.8)%. |
