How to maintain the general badge? Let the person in charge of Pingyang County Signage Factory tell you how to maintain the badge? The badge mainly pays attention to protecting its stable state and avoiding various oxidation reactions. Badges of different materials should also be preserved in different ways.
1: The pure gold badge should be kept on the tray, in the cover, in the cotton box or in a small bag, so as not to collide or be squeezed to avoid mechanical damage.
2: For iron badges, corrosion inhibitors, phosphate or tannate, waxing or outer sealing of polymer materials can be used to stop the outer cover and put it in a more dry place. 3: Sterling silver badges are susceptible to the erosion of sulfur-containing substances to make the color dark. This is black silver sulfide. It is also susceptible to chloride corrosion, forming corner silver (silver chloride). Sterling silver badges are insensitive to light and resistant to high temperature. They should be placed in a place with a clean atmosphere.
4: It is important to pay attention to the copper badge to protect its stable condition and prevent various oxidation reactions. For example, soaking in 5% sodium sesquicarbonate solution, silver oxide closing method, metal corrosion inhibitor, etc. are used to protect the copper badge and keep it in a relatively dry place.
