The maintenance of metal materials mainly includes the following aspects:
Storage environment: Metal materials should be stored in a dry and sealed environment, avoiding humidity and high temperature. Humidity and high temperature will cause metal oxidation and corrosion, affecting its performance and life.
Avoid contact with chemicals: Metal materials should be kept away from chemicals such as acids, alkalis, salts, etc., which will react chemically with metals, causing corrosion and damage.
Prevent friction and collision: Metal materials should avoid friction and collision with hard objects during use to avoid scratches and deformation. Especially precious metals such as gold and silver, which are softer in texture, need more attention to protection.
Regular cleaning: Use a mild detergent and soft cloth to wipe the metal surface regularly to remove dirt and dust. For metals of different materials, the cleaning method is also different. For example, gold can use mild soapy water or professional cleaning fluid, and silver can use toothpaste or professional silver washing water.
Rust-proof treatment: For metal objects that are stored for a long time or are not used frequently, you can apply anti-rust oil or use anti-rust packaging materials, such as anti-rust paper, anti-rust bags, etc., to isolate air and moisture and extend the service life.
Electroplating and spraying: Through electroplating or spraying anti-rust paint, a protective layer is formed on the metal surface to improve corrosion resistance and aesthetics. Electroplating is to deposit a protective layer on the metal surface through an electrochemical reaction, and spraying is to spray anti-rust paint directly on the metal surface to form a solid coating.
Use desiccant and nitrogen filling: Place desiccant in the container where metal materials are stored to absorb moisture, or fill nitrogen in the packaging space to remove oxygen and reduce the chance of oxidation.
