中文摘要 | 現今飯店、旅館、餐廳等公共使用空間之室內裝潢或建築,必須具備及採用難燃、防火及隔熱特性之建築材料是公共安全非常重要的課題。此研究目的亦係針對上述問題集思研發一輕質非玻化之木陶瓷複合材蔚為其用。實驗證明,杉木粒片與無機粘土混合並以 1100 ℃燒結後,可得一多孔狀之複合材;經熱流法檢測其熱傳導,木陶瓷複合材之熱傳導值介於 0.10 至 0.30 W mK-1 之間,其值且會隨杉木粒片之增加而遞減;以黃色粘土及白色粘土燒結之對照組,其熱傳導值分別為 0.29 及 0.26 W mK-1 , 其值均大於木陶瓷複合材及杉木實木之熱傳導值。木材粒片之大小對木陶瓷複合材之熱傳導值並不影響。研究證實,木陶瓷複合材具有高孔隙率及較低之熱傳導率,其絕熱性能足以充當建築用之壁板及其他建築上之利用。 |
英文摘要 | Building materials with properties of good inflammability and high heat insulation are essential for interior decoration and architecture, especially for hotels, restaurants, and other public places, where it is very important that materials are fireproof. The objective of this study was to develop a light non-vitreous wood-ceramic composite (WCC) for building applications. The WCC was made of China fir wood particles and inorganic clay powder sintered at 1100℃. Pores were created inside of the WCC. The thermal conductivity was measured by a heat flow method. The values of thermal conductivity of the WCCs ranged from 0.10 to 0.25 W mK-1. As the amount of wood particles increased in the WCC, its thermal conductivity decreased. The thermal conductivity of the sintered white clay panel (0.29 W mK-1) was higher than that made of yellow clay (0.26 W mK-1). Wood particle size had no significant influence on the thermal conductivity of the WCCs. The thermal conductivities of pure sintered yellow clay and white clay panels were higher than those of both China fir solid wood and the WCC. The heat insulation performance of the WCC appears to warrant its use as wall paneling or other architecture applications as a result of its higher porosity and lower thermal conductivity. |
