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

Abstract

<Abstract > Over the past years, Taiwan forest巳rs hav巴 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-c1osed 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 0 C for 2 hours in semi -c1osed dry kiln, the residual carbonized pin巳 leaf (abbreviated as pine c訂bon) can be ground to carbon powd巳r (pass 200-mesh screen) in a grinder. In view of the color (expressed as CIEL冶'b' : 29/0.33/1.81and BL': 3 1. 14) and gloss : 36.39毛 for a 6% carbon black and Direct Black 38 of 6% added black paper and dyestuff loss in white water during sheet forming , the pin巳 carbon containing black paper (100 g 1m) is comparable to that of commercial carbon filled black paper. <
