铜雕如何保养呢?

作者: 来源: 日期:2019-10-8 7:16:03 人气:0

保持铜雕原貌,有个收藏保管问题,铜雕在地下经过长期腐蚀氧化,质地已不坚固,特别是半脱胎铜雕,甚至比瓷器还易损,因此对铜雕妥善保存,防止出土后受损,对投资者来说十分重要。

To maintain the original appearance of copper carving, there is a problem of collection and preservation. After a long period of corrosion and oxidation in the underground, the texture of copper carving is not strong, especially the half-bodied copper carving, which is even more vulnerable than porcelain. Therefore, it is very important for investors to properly preserve copper carving and prevent damage after excavation.

出土的铜雕经常是泥锈混浊,纹饰不清,进行适当的清洗,让泥土自行脱落,而后用小毛刷轻轻刷洗,遇到有影响纹饰的土锈,可用小竹签慢慢剔除,切忌用铜刷或硬毛刷着力刷洗,更不能用利器清理打磨,否则会毁坏铜雕,而失去收藏价值。

The unearthed copper carvings are often muddy, unclear decoration, proper cleaning, so that the soil will fall off, and then gently brush with a small brush, encounter the soil rust that has an impact on decoration, can be slowly removed with a small bamboo stick, do not use a copper brush or hard brush to brush, and can not use sharp tools to clean and polish, otherwise it will destroy the copper carvings, and lose collection value.

那么如何对铜雕进行保护保养呢?

So how to protect and maintain the bronze sculpture?

①氧化银法。用氧化银与氧化亚铜接触,封闭氯化亚铜的暴露面,达到控制腐蚀铜雕的目的。先用机械方法,剔除粉状锈,露出灰白色蜡状物氯化亚铜。然后将氧化银与酒精调成糊剂,涂在氯化亚铜表面,并置于潮湿环境中,使其充分作用,形成氧化亚铜和氯化铜,覆盖氯化亚铜表面。两者皆为稳定性盐,如此多次操作,直至将器物置于高湿环境中仍不出现粉状锈的腐蚀点为止。此法适于斑点状局部腐蚀的器物及有金属镶嵌物的器物。

(1) Silver oxide method. The exposed surface of cuprous chloride is sealed by contacting silver oxide with cuprous oxide to control the corrosion of copper carving. First, the powder rust was removed by mechanical method, and the grey waxy cuprous chloride was exposed. Then silver oxide and alcohol are mixed into paste and coated on the surface of cuprous chloride, and placed in a humid environment to make it fully functional, forming cuprous oxide and cuprous chloride, covering the surface of cuprous chloride. Both are stable salts, which are operated so many times until no powdery rust corrosion spots are found in the high humidity environment. This method is suitable for speckle locally corroded and metal mosaic articles.

②苯骈三氮唑法。苯骈三氮唑是杂环化合物,与铜及其盐类能形成稳定络合物,在铜合金表面生成不溶性且相当牢固的透明保护膜,使铜雕病被抑制并稳定下来,防止水蒸气和空气污染物的侵蚀。用蒸馏水和甲苯、丙酮等有机溶剂,清除铜雕表面泥土油污,然后浸入苯骈三氮唑酒精溶剂中进行渗透,即可形成络合物保护膜。但苯骈三氮唑易受热升华,失去保护作用,所以最后应在铜雕表面涂一层高分子材料,做封护膜。

(2) Benzotriazole method. Benzotriazole is a heterocyclic compound. It can form a stable complex with copper and its salts. It can form an insoluble and fairly solid transparent protective film on the surface of copper alloy, which can restrain and stabilize copper carving and prevent the erosion of water vapor and air pollutants. Using distilled water and organic solvents such as toluene and acetone to remove clay and oil contamination on the surface of copper carving, and then immersed in benzotriazole alcohol solvent for penetration, a complex protective film can be formed. However, benzotriazole is easily sublimated by heat and loses its protective effect. Therefore, a layer of macromolecule material should be coated on the surface of the copper carving as a protective film.

③碱液浸泡法。将被腐蚀的铜雕置于倍半碳酸钠溶液中浸泡,使铜的氯化物逐渐转换为稳定的铜的碳酸盐,铜雕的氯离子被置换出来转入浸液中。浸液需定时更换,直至浸液中无氯离子出现为止。随后将器物用蒸馏水反复清洗,除去碱液,干燥后封护。碱溶液仅把氯化物提取出来,保留着色彩斑斓的孔雀石等腐蚀层,不损害铜雕的原貌。此法缺点是置换反应时间长;另外氯化物不仅附在锈层表面,而且已渗入器物腐蚀结壳的深部,难以置换彻底。

(3) Alkali immersion method. The corroded copper carving is immersed in sodium sesquicarbonate solution, so that the chloride of copper is gradually converted into stable copper carbonate, and the chloride ion of the copper carving is replaced and transferred into the immersion solution. The leaching solution should be replaced regularly until chloride-free ions appear in the leaching solution. Subsequently, the utensils were repeatedly cleaned with distilled water to remove the lye and sealed after drying. Alkali solution only extracts chloride and retains colorful corrosive layers such as malachite, without damaging the original appearance of copper carvings. The disadvantage of this method is that the replacement reaction time is long; moreover, chloride not only attaches to the surface of the rust layer, but also penetrates into the deep part of the corrosion crust of the apparatus, which makes it difficult to replace completely.
