Whats the Copper-free mirrors ?
Copper-free mirrors are also known as environmentally friendly mirrors. As the name implies, the mirrors are completely free of copper, which is different from ordinary copper-containing mirrors. The mirror is provided with a very dense passivator on the surface. To protect the film, it can effectively prevent the mirror from being scratched, and according to related experiments, the service life of the copper-free mirror is longer than that of other mirrors.
Whats the Silver mirrors ?
In the production process of silver mirrors, after the reflective layer of silver is plated, a layer of copper is plated to protect it. The purpose of this is to prevent the mirror from being damaged. For copper-free mirrors, the copper protective film is replaced with a passivating agent. Membrane is not only environmentally friendly but also extends the service life.
What is the difference between copper-free mirror and silver mirror ?
The difference between a copper-free mirror and a silver mirror is whether the mirror surface has a copper-plated element. Through investigation, it is shown that the copper-free mirror's wear resistance, adhesion, and corrosion resistance are better than those of ordinary silver mirrors, and the reflectivity is higher. . The use time of copper-free mirrors is longer than that of ordinary silver mirrors, so most people will prefer copper-free mirrors when choosing.
