According to the material, the mirror can be divided into acrylic mirror, aluminum mirror, silver mirror and non-copper mirror.
Acrylic mirror, whose base plate is made of PMMA, is called mirror effect after the optical-grade electroplated base plate is vacuum coated. Plastic lens is used to replace glass lens, which has the advantages of light weight, not easy to break, convenient molding and processing, and easy coloring. Generally, it can be made into: single-sided mirror, double-sided mirror, mirror with glue, mirror with paper, semi-lens, etc. can be made according to different requirements. Disadvantages: unable to withstand high temperature and poor corrosion resistance. Acrylic mirror has a big defect, that is, it is easy to be corroded. Once it comes into contact with oil and salt, it will be corroded and distorted in the sun.
Because the aluminum layer is easy to oxidize, the mirror surface is dark, and the aluminum layer does not fit tightly with the glass. If the edge seam is not tight, water will enter from the gap, and the aluminum layer will peel off after water enters, the mirror surface is easy to deform, and the service time and price are also lower than those of the silver mirror.
The silver mirror has a bright surface, high density of mercury, easy to fit with the glass, not easy to get wet and can be used for a long time, so most of the waterproof mirrors sold on the market are silver mirrors.
A copper-free mirror is also called an environment-friendly mirror. As the name suggests, the mirror is completely free of copper. It is a dense passivation protective film on the silver layer, which effectively prevents the silver layer from scratching, and has a long service life. It includes a glass substrate. One side of the glass substrate is coated with a silver layer and a paint layer, and a layer of passivation film is set between the silver layer and the paint layer, The passivating agent film is formed by neutralization reaction of the aqueous solution of acid salt and alkaline salt on the surface of silver layer. The paint layer comprises a primer applied on a passivating agent film and a topcoat applied on the primer.
According to the scope of use, mirrors can be divided into bathroom mirrors, cosmetic mirrors, full-body mirrors, decorative mirrors, advertising mirrors, auxiliary decorative mirrors, etc.
