【摘要】：成都商业街船棺葬,是迄今为止发现规模最大的船棺合葬墓。为了有效地保护遗址中出土的船棺、独木棺等大型木质文物,需要对棺木所存在的各种病害进行科学地认知。本研究利用傅立叶变换红外光谱仪,从化学成分角度对出土棺木的糟朽病害情况进行了剖析。结果表明,出土棺木中半纤维素几乎完全流失、纤维素含量降低、木质素的含量相对上升,纤维素大分子链发生降解。因此,需要对船棺、独木棺等进行必要的加固处理,才能避免棺木在干燥过程中发生皱缩、开裂等形变。
[Abstract]:Chengdu commercial street boat coffin burial, is the largest ship coffin found so far.In order to effectively protect the large wooden relics such as ship coffins and wood coffins unearthed in the site, it is necessary to scientifically recognize the various diseases existing in the coffins.In this study, Fourier transform infrared spectroscopy (FTIR) was used to analyze the rotten diseases of unearthed coffins from the point of view of chemical composition.The results showed that the hemicellulose was almost completely lost, the cellulose content decreased, the lignin content increased, and the macromolecular chain of cellulose was degraded in the unearthed coffin.Therefore, it is necessary to strengthen the coffins of ship and wood in order to avoid the deformation such as shrinkage and cracking in the drying process of coffins.
