宁波“小白礁Ⅰ号”清代沉船位于浙江宁波象山石浦北渔山岛海域,约下沉于清代道光年间。经过长期的水下埋藏,“小白礁Ⅰ号”沉船船体遭受了一定程度的破坏。为了解“小白礁Ⅰ号”沉船所受腐蚀作用及机理,为后续保护处理提供依据,并为其他沉船保护提供借鉴,在沉船发掘工作期间,对遗址堆积情况进行了重点调查,并采集相关水样和沉积物样品进行了多项分析研究。研究表明:由于五列南北向石板的压仓以及细泥和海蛎壳堆积的覆盖,使得“小白礁Ⅰ号”船体底部得以留存但部分船体破坏严重;“小白礁Ⅰ号”沉船处于含盐量高、铁离子和硫酸根离子含量较高、有机质含量丰富的偏碱性水环境,船体木材中盐富集且含有较多的硫铁化合物;在对船体进行保护处理时,脱水定形保护前必须进行脱硫脱盐处理。
Ningbo “white reef I” Qing shipwrecks in Ningbo, Zhejiang Xiangshan Shipu Yushan Island waters, about to sink in the Qing Dynasty Daoguang years. After a long period of underwater burial, the hull of the “White Cattle I” suffered a certain degree of damage. In order to understand the corrosive effect and mechanism of sunken wreck in “Baihajiao I”, provide basis for subsequent protection and provide reference for other shipwreck protection. During the excavation of wreck, the investigation of the site accumulation was carried out. A number of analytical studies were conducted to collect relevant water and sediment samples. The research shows that the bottom of hull of “Baidiao reef Ⅰ” can be preserved but some of the hulls are damaged seriously because of the compaction of five columns of north and south to the slate and the accumulation of fine mud and oyster shells. "The sunken ship is in an alkaline water environment with high salinity, high iron ion and sulfate ion content and rich organic matter content. The hull wood is enriched in salt and contains more sulfur iron compounds. In the hull protection treatment , Desulfurization and desalination treatment must be carried out before the dewatering setting protection.
