What are the three major differences between silver mirrors and aluminum mirrors?
The appearance of silver mirrors and aluminum mirrors is very similar, but the cost of materials used in the production of silver mirrors is significantly higher than that of aluminum mirrors.
Not only that, in terms of labor costs, the production process of silver mirrors is also more complicated, and the price and texture will of course be different. the difference. Specifically, the first difference is that the silver mirror is made of silver electroplating, while the aluminum mirror is made of metal aluminum; the second difference is that the price of the silver mirror is much higher than that of the aluminum mirror, and the aluminum mirror is low in cost and durable, just don’t put it in the bathroom It should be placed in a dry place; difference three, in terms of brightness, the refraction performance of the silver mirror is better than that of the aluminum mirror, and the silver mirror will appear brighter under the same light intensity.
Aluminum mirror is also called aluminized mirror, aluminum mirror, glass mirror, mirror glass, mirror plate glass. The high-reflective aluminum mirror system uses high-quality float glass as the original film, which is cleaned and polished in sequence, high-vacuum metal deposition aluminum plating, rapid oxygen reaction, the first corrosion-resistant paint and drying, and the second waterproof and hardened paint It is made by drying and other processing procedures.
High-grade float aluminum mirrors can be made into tinted mirrors of various colors. Colored mirrors can add different decorative effects, such as gray mirrors, brown mirrors, green mirrors, blue mirrors, etc.
Silver mirrors are commonly known as waterproof mirrors, mercury mirrors, silver-plated mirrors on glass surfaces, glass mirrors, mirror glass, etc. Silver mirrors are widely used in furniture, handicrafts, decoration, bathroom mirrors, vanity mirrors, optical mirrors, and car rearview mirrors. When storing mirrors, they should not be stacked together with alkaline and acidic substances, and should not be stored in humid environments.
Silver mirror also refers to the phenomenon that reducing sugar reacts with Torrens reagent to form simple silver on the test tube wall during the reducing sugar test. So how to distinguish silver mirror and aluminum mirror?
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 deeper, 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.
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 silver mirror and the aluminum mirror are vividly painted differently
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.
How to distinguish between silver mirror and aluminum mirror?
1. First, look at the reflection clarity of the silver mirror and aluminum mirror
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 deeper, 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.
2. Secondly, look at the difference between the back coating of the silver mirror and the aluminum mirror
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.
Again, contrast method to distinguish silver mirror and aluminum mirror
Silver mirror and aluminum mirror can be distinguished from the color of the front mirror: the silver mirror is dark and bright, with deep color, and the aluminum mirror is whitish and bright, with 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.
3. Finally, compare the activity of the surface paint
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.
The “silver mirror” uses silver as the electroplating component, while the “aluminum mirror” uses metal aluminum. The difference in material selection and manufacturing process makes the two bath mirrors quite different. The refraction performance of “silver mirror” is better than that of “aluminum mirror”. Under the same light intensity, “silver mirror” will appear brighter.
Nowadays, many people hesitate to choose super white mirror or silver mirror for decoration. So what are the differences between super white mirror and silver mirror? Let’s take everyone to find out.
1. The ultra-white mirror is made of ultra-white glass, also known as colorless glass, high-transparency glass, and low-iron glass. It is a relatively high-grade variety of glass products, with high light transmittance, high transparency, and crystal clear products. , Noble and elegant, known as the “Crystal Prince” of the glass family, while ordinary silver mirrors are made of float glass.
2. Ultra-clear mirror glass has high technological content, is difficult to produce, and has strong profitability. The high quality determines its high price, especially after it is made into an artistic mirror. Quality makes ultra-clear glass a symbol of building identity. Ordinary silver mirrors can be mass-produced quickly, and the production difficulty is small.
3. The ultra-white mirror is much clearer than the ordinary silver mirror, and the geometric angle of object light source reflection is more standardized. The ordinary silver mirror has a low reflectivity, and the reflection performance of the mirror is about 70%. The shape and color are easily distorted, and the service life is short, and the corrosion resistance is poor. .
