摘　　要：对广西种植的16年生杉木树皮的单宁含量进行分析及其栲胶试制,并进行鞣革试验。分析结果显示,杉树皮单宁含量为7.2%,外皮单宁含量为2.4%,内皮单宁含量为12.9%;用内皮制成栲胶的单宁含量为50.6%;鞣革试验结果表明,纯植鞣时鞣透较慢,成革颜色为鲜桃红色,用于复鞣成革柔软丰满,成革各项性能比较良好,可以作为复鞣剂使用。杉木树皮利用开发还有许多工作需要深入研究,其利用价值有待挖掘。The tannin centent from 16-year-old Chinese fir bark planted in Guangxi was studied and its tannin was extracted.It was used to conduct tanning test.It was shown that the tannin content from the Chinese fir bark was 7.2%,the tannin content from the outer Chinese fir bark was 2.4%,the tannin content from the Chinese fir bast was 12.9%(with the purity of 50.6%).Tanning test showed that during pure vegetable tanning,the tanning process was slow,and the finished leather was bright peach red in color.It was used for retanning to make leather soft and plump,with good roperties,and can be used as a retanning agent.There is still much work to be done in the utilization and development of Chinese fir bark,and its utilization value needs to be explored.
