本研究緣起於部分民間拜拜燒香所用之線香的中心軸(線香軸)於燃燒後
會留下黑色或灰黑色的鬚狀殘餘物,為瞭解造成此現象的原因及尋找改善
方法,本實驗以臺灣常見之六個竹種及廠商提供之線香軸為試驗材料,對
其燃燒性質進行試驗,探討影響竹材燃燒灰化性質的因素。並以無機化學
藥品處理竹材,視其是否會影響燃燒殘餘物的顏色,結果發現竹材燃燒後
所留下之黑色殘餘物是因其部分有機物燃燒不完全所致,無機成分對有機
物之殘餘物顏色有重大的影響。許多金屬離子對有機物的燃燒具催化作用
,其中以鈣、鎂離子最能促進有機物的悶燒作用,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,使原為黑色或灰
黑色的竹材殘餘物變為白色或灰白色。以蒸餾水、0.5N HCl、6N HF/6N
HCl的混合酸處理竹材,可在不同的程度上去除其中所含的灰分(礦物質
)。經處理之試樣在熱分析上所表現的熱性質與未處理者不同,與未處理
者相較,去灰分試樣(蒸餾水處理、0.5N HCl處理、6N HF-6N HCl處理)
與添加化學藥品(添加氯化鈣、硝酸鈣、硝酸鎂)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。去灰分處理使線香軸的釋出熱能溫度向較高溫位移(350℃∼550℃之
間)。添加化學藥品處理則使線香軸釋出熱能的溫度範圍縮小,約在330
℃∼480℃之間。
This study was generated by a common problem of joss stick
which left black or gray black residue after bur- ning. In
order to find out some solution , we try to realize the factors
affecting the buring property of bamboos stick which is the
main supporter of joss stick. Six common Taiwan bamboos and 2
joss sticks as experential materials. We treated bamboo samples
with inorganic chemicals to see if they could change the color
of samples'' residue.Result showed that the black residue was
produced due to the imcomplete combustion of bamboo sticks. The
inorganic compotents affect the color of residue significantly.
Some metal ionshave catalystic effect on combustion of organic
materials. In which Ca and Mg could enhance the smoldering
combus- tion to produce a more complete burning. CaCl2, Ca(
NO3)2 or Mg(NO3)2 could change the color of bamboos'' residue
from black or gray black to white or gray white. Treating
bamboo samples with distilled water, 0.5N HCl and 6N HF/6N HCl
mixed acid could remove inorganic conponents in different
degree. The thermo- property of treated samples showed
different behavior against the untreated samples. The deashed
samples (treated with distilled water, 0.5N HCl or 6N HF/6N
HCl) and chemical-added samples (treated with CaCl2, Ca(NO3)2
or Mg(NO3)2) are produced a sharp mass loss in a smaller
temperature range and were shift the first differential
thermogravity mass loss to a higher tempe- rature. The
exothermal reaction of deashed samples was shift to a higher
temperature (350℃∼550℃).And the temperature range of
exothermal reaction of chemical-added samples was become narrow
at about 330℃∼480℃.
