주사전자현미경(SEM) 관찰을 통한 수침대나무 강화제 연구

Abstract

Since excavation of Taean Mado Shipwreck No.1, many artifacts made of bamboo have been excavated. so we conducted a first experiment to find consolidation material for dimensional stabilization treatment. The experiment was conducted consolidation materials on the conservation for waterlogged wood, and the sample using vacuum freeze drying after water-soluble PEG impregnation maintained the shape well and the color was bright after the treatment. The method applied to conservate the bamboo artifacts excavated from Mado shipwreck No. 1, 2 and 3. However, some disadvantages have been identified after conservation in this way. There is a high possibility of warpage during vacuum freeze drying and after the conservation is completed, the strength is weakened, requiring much attention to management and movement. In the second consolidation material selection experiment, it was confirmed whether PEG of various average molecular weights could complement the strength. In order to maintain the strength, it was thought that a high degree of the consolidation material distribution in the sample was good. The extent of the distribution of the consolidation material was observed by scanning electron microscope, and the degree of distribution of the sample was not maintained or the strength was improved even when compared with the visual observation of the sample. Through this, it was confirmed that there is no correlation between the degree of distribution and the strength.
