How to distinguish the type of mirror aluminum plate?

 Aluminum mirror reflect different points from low to high good grade, mirror film, which contains 5052 aluminum plate, aluminum mirror polished, entrance mirror polished aluminum, aluminum mirror entrance oxide, and super aluminum mirror.

 Choose a reflector that suits you according to the characteristics and positioning of your product. If you want to make a product with high quality of life, then choose a mirror with different entrances. If it is low-end, choose a domestic one. The feature of domestic mirrors is that there is no problem with the environmental protection data processing between surfaces, the mirror rate will change with the change of learning time, and the price is relatively cheap; the feature of imported products is that the reflectance is not messy, divided into 86% ordinary mirrors and 95% %The ultra-mirror design has two grades, and the price is slightly more expensive.

 The mirror surface is made in Germany and Italy, and the mirror surface in Japan is not oxidized, and it is made of sheets of different sizes and specifications, and the loss is high. However, its unique texture effect has been favored by manufacturers of electronic technology product structure shells.

 Simple test method:

 At the entrance of the mirror aluminum plate, after tearing off the protective film, touch the mirror with your fingers, the sweat of your fingers will stay on the mirror, but wipe it with a dry cloth or paper towel, and the fingerprints will be wiped clean without leaving any traces.

 The domestic mirror aluminum plate is different, and the finger prints left will become more and more dirty after being rubbed, and the effect of a mirror surface cannot be restored in the end.

 There is another test method:

 Put a small aluminum plate to your ear and bend it quickly. If you can hear a slight tearing sound, it proves that it is an imported aluminum oxide plate, otherwise it is a domestic ordinary polished plate. Because the surface of the oxidized mirror aluminum plate of the network entrance itself develops a layer of oxide film similar to corundum, because the structure analysis of the aluminum itself is different from that of the oxide film, the oxide film will burst and make a slight tearing sound when bending.
