摘要
漂白对中国书画纸,特别是宣纸的影响情况未见系统的研究。为此,首先研究常用漂白剂-漂白粉(次氯酸钙)对宣纸的影响,又将硼氢化钠、过氧化氢、高锰酸钾和次氯酸钙四种漂白剂进行比较。结果表明,次氯酸钙具有加速纸张老化的作用,在文物保护过程中应该尽量避免使用漂白粉。不同的漂白剂对纸张的影响不同。因此在文物保护中,要弄清各种斑点产生的原因,首先采用水洗等物理方法,无法去除时再慎重选择漂白方法。
The influence of bleaching on Chinese painting paper, especially Xuan paper, has not been systemically studied. In this work, the influence of calcium hypochlorite ( bleaching powder, Ca ( CIO ) 2 ), a frequently used bleaching agent, on Xuan paper was investigated. In comparison with other bleaching agents NaBH4, H2O2 and KMnO4, calcium hypochlorite can accelerate the aging of Xuan paper. The use of calcium hypochlorite in the paper conservation should thus be avoided. Besides, as different bleaching agents have different effects on paper, it's necessary to clarify the causes of stains in the paper and select a suitable agent for bleaching.
