Why do bathroom mirrors have spots?

by:CBM     2021-08-07
When looking at the mirror, I found some black spots on the bathroom mirror, which affected the use of the bathroom mirror. But why the bathroom fittingsmirror is smooth and stain-free, but also has spots? In fact, this kind of situation is not uncommon. The bright and beautiful bathroom mirrors are exposed to the water vapor in the bathroom for a long time, and the edges of the mirror will gradually darken and even gradually spread to the center of the mirror. The reason is that the surface of the mirror is usually manufactured by electroless silver plating, and silver nitrate is the main raw material. There are two cases of black spots. One is that the protective paint and silver coating on the back of the mirror peel off in a humid environment, and the mirror does not have a reflective layer. Second, in a humid environment, the silver-plated layer on the surface is oxidized into silver oxide by air. The silver oxide itself is a black substance, causing the mirror to look black. mirrors are cut. The exposed edges of the cbm mirror are easily corroded by moisture. This corrosion often starts from the edge and gradually spreads to the center, so the edge of the cbm mirror must be protected. Use glass glue or edge banding to seal the edge of the mirror. In addition, it is best not to lean against the wall when installing the mirror, leaving some gaps to help the mist and water vapor evaporate. Once the mirror turns black or spots, there is no way to relieve it, but to replace it with a new mirror. Therefore, reasonable use and maintenance on weekdays become very important; CBMLED anti-fog bathroom mirrors keep the bathroom mirrors in the bathroom away from the damage of fog. mirror factory production, wholesale sales.
