Outline of Final Research Achievements

With the conservation treatment of large wooden objects found at the undersea ruins, especially the wreck, in mind, we proceeded with the research for the following two purposes. (1) Manufacture a solar thermal collectors and heating circulation device, and carry out conservation processing of large wooden objects excavated from undersea ruins. (2) Investigate the mechanism of suppressing rusting of iron parts of wood objects excavated from undersea ruins by trehalose.
Specifically, it was confirmed that a solar thermal collectors and heating circulation device was manufactured and used and could withstand practical use. Regarding research on iron rust suppression, empirical and scientific research revealed that trehalose inhibits the electrical behavior that is a necessary requirement for iron rusting.

Academic Significance and Societal Importance of the Research Achievements

我が国においては海底遺跡出土大型木製品の保存処理は継続的に実施されておらず、現在は止まった状況にある。今回の太陽熱集熱加熱循環装置とトレハロースによる鉄部錆化抑止メカニズムに関する研究で得られた成果や様々なデータの蓄積によって、元寇沈船の引き上げと保存処理に着手できる段階に到達したと言える。
