中文摘要 | 有些金屬元素對有機物的燃燒具催化作用。本研究以無機鹽類處理竹材,來瞭解其影響竹材燃燒的性質,結果發現,以鈣、鎂化合物最能促進竹材悶燒作用,使其燃燒更完全。氯化鈣、硝酸鈣、硝酸鎂可有效改變竹材燃燒殘餘物的顏色,可使原為黑色或灰黑色的竹材殘餘物變為白色或灰白色。添加無機鹽類試樣在較小的溫度範圍內產生急劇的重量損失,且使產生最大示差熱重量損失的溫度向較高溫位移。添加無機鹽類處理使線香軸放熱反應的溫度範圍縮小,約在330~480℃之間。 |
英文摘要 | Some matallic elements have catalystic effect on combustion of organic materials. In this study, inorganic salts were used to treat bamboo incense stick and the results showed that calcium and magnesium could enhance the smoldering combustion to produce a more complete burning. Calcium chloride, calcium nitrate and magnesium nitrate could change the color of bamboo residue from black or gray black to white or gray white. Inorganic salt treated samples were produced a sharp mass loss in a smaller temperature range and shifted the first differential thermogravity mass loss to a higher temperature. Their temperature range of exothermal reactions were also become narrow at about 330-480℃. |
