| 铜雕保养氧化银法。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。 The silver oxide process is maintained by copper carving. The exposed surface of cuprous chloride is closed by contacting silver oxide with cuprous oxide, so as to control the corrosion of copper carving. First, remove the powdery rust by mechanical method, and expose the ash white wax like cuprous chloride. Then silver oxide and alcohol are mixed into paste, which is coated on the surface of cuprous chloride, and placed in a humid environment to make it fully function, forming cuprous oxide and cuprous chloride, and covering the surface of cuprous chloride. Both of them are stable salts, so many times of operation, until the utensil is placed in a high humidity environment, there is still no corrosion point of powdery rust. This method is suitable for the articles with spot local corrosion and the articles with metal inlay. |
