Aluminum mirrors can also be called aluminum-coated mirrors, etc. The high-reflection aluminum mirror series uses high-quality float glass as the substrate, which is cleaned and polished in turn, high-vacuum metal deposition is aluminum-plated, oxygen reaction is fast, the first corrosion-resistant paint and baked After drying, the second coat of waterproof hardening paint and drying and other processing procedures are made.
Commonly known as waterproof mirrors, silver mirrors are widely used in furniture, handicrafts, bathroom mirrors, etc. When storing mirrors, they should not be stacked together with alkaline and acidic substances, and should not be stored in humid environments.
Then, what is the difference between the aluminum mirror and the silver mirror mentioned above? I will let you understand.
The reflection clarity of silver mirror and aluminum mirror is different
Compared with the paint on the surface of the silver mirror and the paint on the surface of the aluminum mirror, the paint on the silver mirror is darker, while the paint on the aluminum mirror is lighter. The silver mirror is much clearer than the aluminum mirror, and the geometric angle of object light source reflection is more standardized. The reflectivity of aluminum mirror is low, the reflective performance of ordinary aluminum mirror is about 70%, the shape and color are easy to be distorted, and the life is short, the corrosion resistance is poor, and it has been completely eliminated in European and American countries. However, aluminum mirrors are easy to mass-produce, and the cost of raw materials is relatively low.
The back coating of silver mirror and aluminum mirror is different
Generally, silver mirrors are protected by more than two layers of paint. Scratch off part of the protective paint on the surface of the mirror. If the bottom layer shows copper color, it proves to be a silver mirror, and if it shows silvery white, it proves to be an aluminum mirror. Generally, the back coating of the silver mirror is dark gray, and the back coating of the aluminum mirror is light gray.
Silver mirror and aluminum mirror have different brightness of front color
The silver mirror is dark and bright, with a deep color, while the aluminum mirror is whitish and bright, with a beautiful color. Therefore, silver mirrors are distinguished only by color: the color of the back is gray, and the color of the front is deep, dark and bright. When the two pieces are put together, the shiny and whitish one is the aluminum mirror.
The surface paint activity of silver mirror and aluminum mirror is different
Silver is an inactive metal, while aluminum is an active metal. After a long time, aluminum will oxidize and lose its color and turn gray, but silver will not. It is easier to test it with dilute hydrochloric acid. The reaction of aluminum is very strong, while that of silver is very slow. Silver mirrors are more waterproof and moisture-proof than aluminum mirrors, and can illuminate more clearly and brightly. They are generally used in wet places such as bathrooms and are more durable than aluminum mirrors.
