摘要
土遗址、石质文物、古代建筑等不可移动的硅酸盐质文物在保存过程中普遍受到了严重的盐损害,致使其所承载的历史艺术信息正在逐渐的失去,危害最大的可溶盐是Na_(2)SO_(4)和NaCl。采用盐结晶抑制剂降低或防止硅酸盐文物盐害是一种去除盐的新手段,旨在降低盐的结晶压力或使盐在文物表面析出,而不沉淀在孔隙中。探讨了影响盐损伤的几个关键因素,总结了盐结晶抑制剂的作用机理及抑制剂在降低硅酸盐文物中NaCl和Na_(2)SO_(4)盐损害中的应用。为硅酸盐文物中盐害的去除提供方法参考,对结晶抑制剂在文物中的应用潜力进行了展望。
Purposes—The immovable silicate heritage such as earthern sites,stone and ancient buildings have been severely damaged by salts in the process of preservation,resulting in the gradual loss of the historical and artistic information they carried.The most harmful soluble salts are Na_(2)SO_(4)and NaCl.The use of crystallization inhibitor is a new method to reduce or prevent salt damage of silicate heritage,which aims to reduce the crystallization pressure of salt or make salt precipitate on the surface of heritage without settling in pores.Methods—Several key factors affecting salt damage are discussed.The action mechanism of crystallization inhibitor and its application in reducing NaCl and Na_(2)SO_(4)damage in silicate heritage are summarized.Result and conclusion—a method reference for the removal of salt damage in silicate heritage is provided,and the application potential of crystallization inhibitors in cultural relics is prospected.
