How to judge the good and bad of the bathroom mirror?
1. Glass and underlying quality
The glass must be placed on the back to be used to imagine. At present, the mirrors on the market are mostly used as silver or aluminum as this layer of reflex. These two materials are quite different. Generally speaking, aluminum mirrors are prone to oxidation and whitening imaging, so life span will be short; silver mirrors are not easy to be oxidized, and they can still be used normally in a humid environment. Because the price of silver mirrors is much higher than aluminum mirrors, some merchants will use aluminum mirrors to counter silver mirrors to obtain huge profits. Consumers must know how to distinguish:
See the reflection clarity
Under normal circumstances, the silver mirror is clearer than the aluminum mirror, and the light source reflection angle is more standardized; the reflectance of aluminum mirror is low, about 70%, and it is easy to distort in shape and color.
Look at the back coating
The protective paint behind the bathroom mirror is scraped. If the bottom layer is copper, it proves that it is a silver mirror. If it is silver, it is proved 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 pale gray.
Look at the paint surface activity
Silver is not active metal, which is not easy to oxidize, and aluminum is active metal and is easy to oxidize. When purchasing, you can need to be in contact with dilute hydrochloric acid. If the response is not obvious, it proves that it is silver mirror. If the response is obvious, it proves that it is an aluminum mirror.
2. Imaging ability
The imaging ability of the bathroom mirror is preferred by clearness and no deformation. You can use the distant straight objects for reference, and observe the quality from multiple angles on the front, side, and negative aspects. In appearance with good quality mirrors, there is no bubble, debris, incomplete, color -changing, etc. In the movement, the straight objects will not bend and deform.
3. Appearance
When buying a bathroom mirror, you can observe whether its appearance is fine. Generally speaking, good quality mirrors must not have bubbles, impurities, discoloration, dark spots, black borders, etc. from the appearance. There must be no peeling, pinholes, impurities attachment, scratches, light dots, etc.
4. Waterproofing and rust resistance
The bathroom environment is humid, and the poor quality bathroom mirror is placed in one of the time. It is prone to rust and paint phenomenon in the edges of the mirror. If you buy a border bathroom mirror, you need to carefully observe whether the seams of the lens and the border are tight. If there are more exposed metal parts in the mirror, you should ask the specific material and confirm that the rust -proof material can be purchased.
