what is the difference between silver mirror and aluminum mirror

2018-08-29


First, look at the reflection of 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 of the silver mirror is more deep, and the paint of the aluminum mirror is lighter. The silver mirror is much clearer than the aluminum mirror, and the reflection angle of the object light source is more standardized. The reflectivity of the aluminum mirror is low, the reflection performance of the ordinary aluminum mirror is about 70%, the shape and color are easily distorted, and the life is short, and the corrosion resistance is poor, which has been completely eliminated in European and American countries. However, aluminum mirrors are easy to mass produce, and raw materials are also relatively low cost.

Second, look at the silver mirror and aluminum mirror back coating distinction

Generally, silver mirrors have more than two layers of paint protection. Scratch the part of the protective paint on the surface of the mirror. If the proof of the copper color on the bottom layer is a silver mirror, the silver-white proof is an aluminum mirror. In general, the back of the silver mirror is dark gray, and the back of the aluminum mirror is light gray.

Again, the contrast method distinguishes between silver and aluminum mirrors.

The silver mirror and the aluminum mirror are distinguished from the color of the front mirror: the silver mirror is dark and bright, and the color is deep, and the aluminum mirror is white and bright, and the color is bleached. Therefore, the silver mirror is distinguished by color: the color of the back is gray, and the color of the front is dark and dark. The two pieces are put together, shiny, and white is the aluminum mirror.

Later, compare the surface paint activity

Silver is an inactive metal. Aluminum is an active metal. When it takes a long time, aluminum will oxidize and lose its natural color. It will become gray. Silver will not. Simpler, it can be tested with dilute hydrochloric acid. The reaction of aluminum is very strong, and silver is very slow. The silver mirror is more waterproof and moisture-proof than the aluminum mirror. The photo is clearer and brighter. It is generally used in the damp place of the bathroom and is more durable than the aluminum mirror.

The appearance of silver mirrors and aluminum mirrors is very similar, but the cost of materials used in silver mirror production is significantly higher than that of aluminum mirrors. Not only that, but in terms of labor costs, the production process of silver mirrors is also more complicated, and the price and texture will certainly be the difference. Specifically, the difference is that the silver mirror is made of silver plating, and the aluminum mirror is made of metal aluminum: the difference is two. The price of the silver mirror is much higher than the price of the aluminum mirror. The cost of the aluminum mirror is low, and it is also durable. The bathroom should be placed in a dry place. When using a silver mirror for a mirror, the price is about 60-70 yuan / square meter, and the price of an aluminum mirror is about 40-60 yuan / square meter. The difference is three, from the brightness, silver. The refractive performance of the mirror is better than that of the aluminum mirror, and the silver mirror will appear brighter under the same light intensity.
