【摘要】：近年来的分析与研究表明,海洋出水沉船的木材中普遍存在大量的以Fe S2和Fe S为代表的硫铁化合物难溶盐,它们在空气中和一定湿度条件下,会氧化生成硫酸,使木材纤维素发生快速降解,从而对木船造成毁灭性的破坏。目前,硫铁化合物的脱除仍然是世界性难题,很多国家发现的木质沉船都面临这方面的困扰。为此,本研究以宁波象山"小白礁I号"清代沉船遗址出水的船体木材构件为研究对象,研发了金属络合剂与氧化剂复配材料EDTAHO,开展了海洋出水木材中沉积的二硫化亚铁的去除技术初步研究,取得了良好的保护效果。本研究结果可为后续脱水定型和加固修复打下良好的基础,有利于海洋出水木质船体的长期保存。
[Abstract]:The analysis and research in recent years have shown that a large number of iron-sulfur compounds, such as FeS2 and FeS, are commonly found in the wood of the shipwrecked marine water, and they oxidize to form sulfuric acid in the air and under certain humidity conditions. The rapid degradation of wood cellulose, thus causing devastating damage to wooden ships. At present, the removal of sulphur compounds remains a worldwide problem, and many wooden sunken ships found in many countries are faced with this problem. In this study, the timber components of the hull of Xiaobai Reef I, Ningbo Xiangshan, were taken as the object of study. The metal complexing agent and oxidant composite material EDTAHOO were developed, and the removal technology of ferrous disulfide deposited in the effluent wood was studied. The results of this study can lay a good foundation for the subsequent dehydration and rehabilitation, and can be beneficial to the long-term preservation of the wooden hull.
