摘要: 研究了杉木炭化前后化学成分的变化情况.分析了杉木经160、190、220℃炭化后,苯-醇抽提物、木质素、纤维素、综纤维素及1%NaOH提取物含量的变化.研究表明:随着炭化温度的升高,苯-醇抽提物、木质素含量呈现上升趋势;纤维素含量总体上呈下降的趋势,综纤维素的含量也呈现下降的趋势,比纤维素的下降要明显;1% NaOH提取物的含量稍微上升.炭化温度较高时,木材内部的营养成分破坏越严重,木材的防腐性能越好,但强度有所下降;炭化温度较低时,能够更好的保持木材的强度及性能,因此应根据实际需要来选择木材的炭化温度.

Abstract: Research on the change of chemical composition of Chinese fir (Cunninghamia lanceolata) wood before and after carbonization was carried out. The contents of alcohol-benzene solubles, lignin, cellulose, holocellulose and1%NaOH extract of the wood after carbonization at 160,190,220℃ respectively were determined. Results showed: with the rise of carbonization temperature, contents of alcohol-benzene solubles and lignin showed a rising trend; cellulose content showed an overall downward trend. Holocellulose content also showed a downward trend, which is more significat than cellulose. One percent NaOH extract content slightly increased. the higher the temperature, the more serious was the damage of the nutritional substance in wood, the better was wood preservative property, but strength was declined. At lower carbonization temperature, the strength and properties of wood can be better maintained. It should be based on actual needs of the timber to choose temperature of carbonization.

Key words: carbonization of wood, chemistry composition, Chinese fir
