출토 탄화 목제유물의 보존처리 : PEG법과 당알코올법 실험비교
A Study on Conservation Treatment for Excavated Carbonization Wooden Object: Comparative Experiment on the PEG Method and Sugar Alcohol Method

출토 부분탄화 목제유물은 물성이 다른 부위가 공존하는 것에 의해 박리와 변형이 일어나기 쉬운 것으로 오래전부터 보고되어 왔지만, 실험연구 등을 통한 연구성과는 많지 않았다. 이번 실험에서는 당알코올법과 일반적으로 널리 사용되고 있는 친수성 수지인 Polyethyleneglycol(PEG)법을 비교 대상 처리법으로 설정하였다. 중량변화율과 수축변화율, 전자현미경(SEM)관찰에 의한 목재조직의 변화양상을 검토한 결과 PEG4000법은 80% 이상 농도까지 단계적 함침이 필요하며 Sugar Alcohol(SA)법은 40% 농도 함침에서부터 안정적인 양상을 보여 단기간 함침의 가능성을 나타냈다. 본 연구에 사용한 판상 부분 탄화재의 변형은 주로 미탄화부의 수축에 의한 현상으로 생각되며 PEG4000법의 경우 최종 함침농도가 20%, 40%, 60%에서, SA법은 20% 농도에 함침한 샘플에서 목재세포조직의 수축이 확인되었다.

It is reported that excavated carbonized wooden objects tend to have more peeling and deformation stemming from the coexisting of different types of parts of objects. However, there is little research results on this. In this experiment, the sugar alcohol method was used and then compared with the results of the PEG4000 method which widely uses. This research targets: prediction of strength by weight increase, investigation of the dimensional stabilization effects by measuring the rate of shrinkage change, condition of drug penetration and change of wood texture by using a scanning electron microscope. As the results, the PEG4000 method needs a phased approach over 80% impregnation. On the other hand, the S A method remains steady from over 40% impregnation. The Deformation of carbonized wooden objects used in this experiment is considered as the phenomenon by shrinkage of non-carbonized parts. The PEG4000 method is verified the shrinkage in the samples treated with 20%, 40% and 60%; the S A method is verified the shrinkage in the samples treated with 20%.
Key Words: PEG4000, Sugar Alcohol, Carbonized wooden objects, Peeling and deformation, Deformation of non-carbonized parts
