馆藏唐代壁画画面霉斑清洗剂的筛选实验研究

为了有效清洗表面留有霉斑的馆藏壁画,筛选有效、安全的壁画表面清洗剂在壁画保护修复中尤为重要。本工作使用5%胰蛋白酶+清洗剂稀释液、5%中性蛋白酶+清洗液稀释液、氨才/乙醇溶液、70%乙醇溶液和去离子水五种生物和化学清洗剂,对壁画模拟霉板、提取和包裹壁画的棉纱及留有霉斑的唐代壁画表面进行清洗实验,筛选出了一种有效的生物清洗剂——胰蛋白酶清洗剂,并配合使用其它几种化学清洗剂可较为有效地清洗多数壁画表面霉斑顽渍。

Study of cleaning agents for removal mildew spot from Tang Dynasty mural paintings in a museum environment

It is important to select effective and safe painting cleaning agent for mildew spots on mural paintings.Five biological and chemical cleaning agents5% trypsinase with dilute cleaning agent; 5% neutral proteinase with dilute cleaning agent; an ammonium hydroxide and ethanol mixture; and 70% ethanol in deionized water were applied separately to a simulated mildew board,cotton cloth used for removing and packaging of the mural painting and to the surface of mildewed Tang Dynasty mural painting.Cleaning experiments suggested that a biological agent,namely the trypsin solution,was effective.This,along with a few other chemical cleaning agents,can remove most of the mildew on the mural painting to be.
