How to distinguish between silver mirror and aluminum mirror

First, look at the silver mirror and aluminum mirror resolution

By contrast lacquer and silver aluminum mirror surface of the mirror surface of the mirror silver paint to be significantly more deep more, paint aluminum mirror opposite of relatively light. Silver mirror a lot clearer than aluminum mirror, the reflected light object geometry more standardized. Aluminum mirror reflectance is low, ordinary aluminum mirror the performance of about 70%, shape and color easily distorted, and short life, poor corrosion resistance, has been completely eliminated in the United States and Europe. However, aluminum mirror easy to mass production, the raw material is relatively low cost.

Secondly, look at the silver mirror and aluminum mirror back coating distinguish

Usually silver mirror has two or more layers of paint protection. Scratch the surface of the mirror part of the protective paint, if it is proved that the underlying copper silver mirror display, the display proved to be silver aluminum mirror. Back-coat layer is generally dark gray silver mirror, aluminum mirror back coating layer is light gray.

Again, the contrast method to distinguish between silver mirror and aluminum mirror

Silver mirror, aluminum mirror from the front mirror to identify the color is: dark silver mirror is bright, deep color, aluminum mirror is bright white, color hair bleach. Therefore, the silver mirror from single color to distinguish: Back now color is gray, the color of the front color deep, dark bright. Two put together, shiny, whitish aluminum mirror.

Finally, compared to the level of activity surface paint

Silver is non-active metals, aluminum is an active metal, aluminum oxidizes a long time to lose color, turn gray, not silver, it may be simpler test with dilute hydrochloric acid, the reaction is very strong aluminum, silver is very slow. Silver mirror is more waterproof than the aluminum mirror moisture, according to the clearer and brighter, generally used in the bathroom or something moist places than aluminum mirror and durable.

The three major differences silver mirror and aluminum mirror

Silver mirror, aluminum mirror look very similar, but the cost of materials used in the production of silver mirror significantly higher aluminum mirror, not only that, the cost of labor, the production process of silver mirror is also more complex, of course, will be the price and texture the difference. Specifically, the difference between a silver mirror silver plating composition, and aluminum mirror using aluminum; the difference Second, the price of silver mirror is much higher than the price of aluminum mirror, aluminum mirror low cost, but also full of durable, is not to put bathrooms should be placed dry place, when the full-length mirror with a silver mirror generally cost about 60-70 yuan / square meters, aluminum mirror cost about 40-60 yuan / square meter; the difference between three brightness from speaking, silver refractive lens performance is superior to aluminum mirror, at equal light intensity of the irradiation, silver mirror will look brighter
