The effective way to protect corrosion copper sculptures must first determine the principle of protection technology for corrosion copper sculptures. Only the protection technology treatment under the premise of strict principles is reasonable and feasible. Years of conservation practices have confirmed that the following principles must be followed: (1) Copper corrosion products should be selectively removed and retained The bronze urns that existed thousands of years ago are corroded to varying degrees. The corrosive covering is a symbol of ancient art, so some corrosion should be preserved, but the copper chloride and basic chlorination of the copper sculpture Copper and so on need to be removed without reservation, eradication of chloride damage to copper sculpture is the key to derusting technology. Ancient bronze rituals, weapons, and bronze mirrors often exhibit mineralized corrosion products such as black lacquer ancient, green lacquer ancient, mercury enamel, and jujube red. If the structure is tight and does not penetrate deep into the copper body, it can generally Reserved. (2) Maintaining the original condition is the basic requirement for protecting bronze sculpture The essence of maintaining the original shape of bronze sculpture is to protect its historical value, artistic value and scientific value. The original shape of the bronze sculpture includes its shape, ornamentation, color, crafts, materials, etc. Therefore, when choosing a technique to treat the corrosion copper sculpture, the first thing to consider is that it does not affect its original shape, especially the change of the appearance color of the bronze sculpture. Any method that obviously changes the color of the corrosion layer of the copper sculpture should be used cautiously. The bronze sculpture cannot be treated beyond recognition, especially the content of the ancient information on the artifact can be preserved. (3) The method used must be tested The chemical composition, structure and corrosion of bronze sculptures are different. The repair method used must have a scientific basis. It must be tested repeatedly beforehand, and then repaired. (4) Careful use of protective materials In the process of protecting the corrosion of copper sculptures, including decontamination, derusting, corrosion inhibition, sealing and other processes, certain chemicals must be used. This must be done with caution, and the amount of chemicals used should be reduced as much as possible. at the lowest limit. NANTONG MASTERPIECE TRADE CO.,LTD , https://www.mpheadwear.com
