China's bronze sculptures have now enjoyed a worldwide reputation. Many people have joined the ranks of bronze sculptures. Of course, one of the problems we have to face is the maintenance of bronze sculptures.

The silver oxide method utilizes the contact of silver oxide with cuprous oxide to block the exposed surface of cuprous chloride to achieve the purpose of controlling the corrosion of the copper sculpture. The powdery rust is first removed mechanically to reveal an off-white waxy cuprous chloride. Next, the silver oxide and the alcohol are adjusted into a paste, coated on the surface of cuprous chloride, and placed in a humid environment, so that it fully acts to form cuprous oxide and copper chloride over the surface of the cuprous chloride, which Both are stable salts, which are operated many times until the object is placed in a high-humidity environment without the corrosion point of powdery rust. This method is suitable for speckle-like localized objects and metal inlaid objects.
The benzotriazole method is a stable complex which forms a stable complex with copper and its salts, and forms an insoluble and relatively strong transparent protective film on the surface of the copper alloy, so that the copper carving disease is suppressed and stabilized. Prevent the erosion of water vapor and air pollutants. The complex oil protective film can be formed by removing the oil stain on the surface of the copper-carved surface with distilled water, an organic solvent such as toluene or acetone, and then immersing it in a solvent of benzotriazole alcohol. However, benzotriazole is susceptible to thermal sublimation and loses its protective effect. Therefore, a layer of polymer material should be applied to the surface of the copper sculpture to make a sealing film.
In the lye immersion method, the etched copper eagle is immersed in a sodium sesquicarbonate solution, and the copper chloride is gradually converted into a stable copper carbonate. The copper ions of the copper stalk are replaced and transferred into the immersion liquid. . The immersion liquid should be replaced regularly until no chloride ions appear in the immersion liquid.
