1. The service life of traditional silver mirrors is relatively short. Generally, black edges and dark spots will appear in half a year to a year. This is because traditional silver mirrors use a metal copper layer as a protective layer after the silver layer is plated. When copper ions come into contact with oxygen molecules in the air, they will react into black copper oxide, which will affect the appearance of the mirror. In addition, the protective ability of traditional mirror back paints is also very limited, and water molecules and some weak acid-base substances can easily pass through the paint layer. As a result, the silver layer is corroded; for the environment, the traditional mirror-making process will not only produce copper-containing wastewater and ammonia, but also the back paint of the mirror contains lead, which will have a certain impact on the human body and the environment. The copper-free and lead-free silver mirrors developed by our company have revolutionized the production process, completely changed people's concept of using silver mirrors, and set off a new wave of health and environmental protection!

 

2. Our company owns the first batch of new copper-free environmental protection lens production lines in China. Now the new generation of copper-free environmentally friendly lens manufacturing technology independently developed by our company breaks through the limitations of traditional lenses. Regardless of the lens quality, environmental protection, and even the production process, it is the crystallization of technology and excellence.

 

(1) The traditional silver mirror uses copper as the main protective material. However, over time, the lens will fog, and the edges will be corroded to appear black edges and black spots, and the image will gradually fade. Our company's new self-developed copper-free environmental protection production line, the new technology adopts an exclusive formula of copper-free production technology. Using an inert substance as the protective layer of the silver layer, we professionally call it a "passivation layer", the black edges and black spots can be delayed for at least 3 times before they appear.

 

(2) The new environmental protection mirror adopts an exclusive formula, and the environmental protection requirements in the production process far exceed international standards. The new technology has greatly reduced the ammonia emissions during the production process. We do not contain lead in the entire production process and materials, including the back paint, which is not harmful to human health and the environment.

 

(3) The mirror back paint uses epoxy paint to replace the traditional back paint materials. Its hardness and anti-permeability are greatly improved. It has a good insulation function for water vapor and acid-base substances. Thereby greatly extending the life of the mirror.
