Manufacturing of Wood Charcoal Cup by Using Carbonization Method and Its Water Repellency

With increased interests in environmental issues, people are looking for new materials that serve special and bio-activated functions. One of interesting materials is charcoal which has excellent adsorption ability for harmful volatile organic compounds, fireproof performance, far-infrared ray emission, and electromagnetic shielding. Since non-crack carbonized board was developed from wood-based composite materials, carbonization method might be applied to woodcraft products such as wood cup and bamboo. In this study, manufacture of wood char-coal bowl was conducted with carbonization method developed in 2009 in order to activate wood products market. Ash tree(Fraxinus rhynchophylla) cup was carbonized at 600℃ with two pretreatments which were phenol resin and wood tar solution treatment. After carbonization of ash tree cup, non-crack charcoal cup were successfully manufactured. Phenol resin treatment af-fected on charcoal cup manufacturing both positively and negatively. For a positive way, it pre-vented shrinkage. For a negative way, it decreased water repellency. On the contrary, wood tar treatment accelerated shrinkage a bit and increased water repellency. Based on the results, wood tar can be used as pre-treatment solution for reducing post-treatment costs. We confirmed woodcraft products can be carbonized without deformation, so carbonization may provide a high value-added products from wood.
