Abstract

This study examines the removal effects of solvents which were applied on three adhesives and three filling materials for ceramics. The chosen materials are Cemedine C, Loctite$^{(R)}$ 401$^{TM}$, Araldite Rapid Type, plaster of paris, CDKI 520A+B, Araldit$^{(R)}$ SV427-2+HV427-1. For the first examination, each different materials were soaked into different solvents, and then the soften level were compared by compressive pressure. The result of the first exam showed that Cemedine C was dissolved easily in acetone. Furthermore Araldite, CDK and SV427 were soften efficiently by Dichloromethan, Tetrahydrofuran and DMX(Dichloromethan+Methanol+Xylene). However, Loctite and plaster were not able to make sample for the first test. Therefore, the second test carried on only. The second examination, chosen effective solvents from the first test were applied with two different methods; soaking and saturated atmosphere. Almost every sample could removed by soaking method in ten minutes, and saturated atmosphere method needs 24 hours for the safety.

국내에서 토기 복원에 주로 사용하는 접착제 3종: Cemedine C, Loctite$^{(R)}$ 401$^{TM}$, Araldite Rapid Type와 메움제 3종: 석고, CDKI 520 A+B, Araldit$^{(R)}$ SV 427-2+HV 427-1의 제거효과에 대해 연구했다. 1차 실험에서 각각의 재료들을 여러 용제에 침적해 연화의 정도(Soften level)를 비교하고, 2차 실험은 연질토기 시료와 경질토기 시료에 재료들로 복원하여 침적법과 증기법의 효과를 비교했다. 1차 실험 결과 Cemedine C와 Loctite는 아세톤에 쉽게 녹았고, Plaster(석고)는 인산나트륨에 효과적으로 제거되었다. Araldite Rapid Type와 CDKI 520과 SV427은 Dichloromethan, Tetrahydrofuran, DMX (Dichloromethan + Methanol + Xylene)에 효과적으로 제거되었다. 2차 연구는 1차 연구를 토대로 제거에 효과적이라 판단되는 용제를 각각 침적법과 증기법으로 제거하였다. 대부분의 시료에 적용된 재료들은 침적법으로 10분 이내에, 증기법으로는 약 24시간 후에 제거되었다.
