碳化台灣二葉松落葉製造黑紙之研究

The Manufacture of Black Paper from the Carbonized Fallen Leaves of Taiwan Red Pine

乾旱季節的南台灣原始台灣二葉松富含油脂及樹脂落葉，經久不易分解，易引起森林火災。將二葉松落葉自林地移走，實有所難。利用裝在小卡車上之乾餾設備，運至二葉松林地，就地利用部份落葉當燃料乾餾（420℃、2 hr）二葉松葉，除可得餾出液外，尚可就殘留碳化針葉，磨成細碳粉（通過200 網目），供作黑紙之黑色料。經本試驗所製得之基重100g / m2 黑紙顏色CIELAB 值分別為29／0.33／-1.81，光澤度（75°）36.3% 足可比美含工業用黑碳粉黑紙之顏色。 Over the past years, Taiwan foresters have looked at the damages caused by the forest fires partly came from the oil and resin containing fallen pine leaves in southern Taiwan in dry season. Removal of the fallen leaves of Taiwan Red Pine (Pinus taiwanensis Hayata) from forest is impractical and not economic, so it seems feasible to transport a semi-closed drying kiln by truck to the forest site to incinerate the fallen leaves in situ. Besides the distillate collected from the leaves of red pine's dry distillation at 420°C for 2 hours in semi-closed dry kiln, the residual - carbonized pine leaf (abbreviated as pine carbon) - can be ground to carbon powder (pass 200-mesh screen) in a grinder. In view of the color (expressed as CIE L*a*b* : 29/0.33/-1.81and BL* : 31.14) and gloss : 36.3% for a 6% carbon black and Direct Black 38 of 6% added black paper and dyestuff loss in white water during sheet forming, the pine carbon containing black paper (100 g /m2) is comparable to that of commercial carbon filled black paper.
