【摘要】：近年來的分析與研究表明,海洋出水沉船的木材中普遍存在大量的以Fe S2和Fe S為代表的硫鐵化合物難溶鹽,它們在空氣中和一定濕度條件下,會氧化生成硫酸,使木材纖維素發(fā)生快速降解,從而對木船造成毀滅性的破壞。目前,硫鐵化合物的脫除仍然是世界性難題,很多國家發(fā)現(xiàn)的木質(zhì)沉船都面臨這方面的困擾。為此,本研究以寧波象山"小白礁I號"清代沉船遺址出水的船體木材構(gòu)件為研究對象,研發(fā)了金屬絡(luò)合劑與氧化劑復(fù)配材料EDTAHO,開展了海洋出水木材中沉積的二硫化亞鐵的去除技術(shù)初步研究,取得了良好的保護(hù)效果。本研究結(jié)果可為后續(xù)脫水定型和加固修復(fù)打下良好的基礎(chǔ),有利于海洋出水木質(zhì)船體的長期保存。
[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.
