【摘要】:正目前,用于文物表面清洗的多糖類水凝膠一般為固體塊狀或呈半固態(tài),敷于待清洗區(qū)域,使得有效的活性組分發(fā)揮清洗效果。本研究通過將預(yù)成型的瓊脂凝膠磨碎成可以刷在文物表面上的微小顆粒,用于文物的表面清潔。瓊脂提取自海藻,可用作增稠劑,在食品工業(yè)中有廣泛應(yīng)用。瓊脂的凝固點(diǎn)和熔點(diǎn)溫度不同,熔點(diǎn)約85~90℃。本研究通過實(shí)驗(yàn)論證了一種可用于水敏性文物表面清洗的簡便方法,創(chuàng)新點(diǎn)在于將瓊脂凝膠磨碎后的小顆粒刷于污面處的處理方式。
[Abstract]:At present, the polysaccharides hydrogels used for the surface cleaning of cultural relics are usually solid block or semi-solid, which is applied to the area to be cleaned, so that the effective active components can exert the cleaning effect. In this study, the preformed Agar gel was ground into tiny particles that could be brushed on the surface of the cultural relic, and used to clean the surface of the cultural relic. Agar extracted from seaweed can be used as thickener and widely used in food industry. The freezing point and melting point temperature of Agar are different, the melting point is about 8590 鈩,
