Aluminum mirror is also called aluminized mirror, aluminium mirror, glass mirror, mirror glass, mirror plate glass. High reflective aluminium mirrors are made of high-quality float glass sheets, which are washed and polished in turn, aluminized by high vacuum metal deposition, rapid oxygen reaction, first corrosion resistant paint and drying, second waterproof and hard paint and drying. Advanced float aluminium mirrors can be made into colored mirrors of various colors to increase different decorative effects, such as gray mirrors, brown mirrors, green mirrors, blue mirrors, etc. The thickness ranges from 1.1 mm to 8 mm, and the size of the aluminium mirror plate is 2440 x 1830 mm. Silver mirror commonly known as waterproof mirror, mercury mirror, glass surface silver mirror, glass mirror, mirror glass, etc. Silver mirrors are widely used in furniture, crafts, decoration, bathroom mirrors, makeup mirrors, optical mirrors, and automotive rearview mirrors. When storing mirrors, they should not be stacked with alkaline and acidic substances to avoid being stored in a humid environment. Silver mirror also refers to the phenomenon that reducing sugar reacts with Torrens reagent in reducing sugar test to produce elemental silver on the wall of test tube. So how to distinguish silver mirror from aluminium mirror in the end? Silver mirror and aluminium mirror have different reflective clarity Compared with the paint on the surface of the silver mirror, the paint on the silver mirror should be deeper, while the paint on the aluminum mirror is lighter. Silver mirrors are much clearer than aluminium mirrors, and the reflectance geometry of object light sources is more standardized. Aluminum mirrors have low reflectivity, about 70% reflectivity of ordinary aluminum mirrors. They are easily distorted in shape and color, and have short life and poor corrosion resistance. They have been completely eliminated in European and American countries. However, aluminium mirrors are easy to produce on a large scale and the cost of raw materials is relatively low. Different coatings on the back of silver mirror and aluminium mirror Generally silver mirrors are protected by two or more layers of paint. Scrape part of the protective paint on the mirror surface. If the copper proof on the bottom is silver, the silver proof is aluminum. Generally, the back coating of silver mirror is dark gray, while that of aluminium mirror is light gray. The front color brightness of silver mirror is different from that of aluminium mirror. Silver mirrors are bright and dark, while aluminium mirrors are white and bleaching. So silver mirrors can be distinguished only by color: the color on the back is grey, the color on the front is dark and bright. Two pieces together, shiny, white is the aluminum mirror. Silver mirror and aluminium mirror have different surface paint activity Silver is an inactive metal. Aluminum is an active metal. Over time, it will oxidize and lose its original color. Silver will not. Simpler, it can be tested with dilute hydrochloric acid. The reaction of aluminium is very strong, while that of silver is very slow. Silver mirrors are more waterproof and moistureproof than aluminium mirrors. They shine more clearly and brightly. They are usually used in wet places in bathroom or something and are more durable than aluminium mirrors. There are three major differences between silver mirror and aluminium mirror: the appearance of silver mirror and aluminium mirror is very similar, but the material cost of making silver mirror is obviously higher than that of aluminium mirror. Moreover, as far as labor cost is concerned, the process of making silver mirror is more complicated, and the price and texture of silver mirror will certainly be different. Specifically, silver mirrors are silver plated, while aluminium mirrors are metal aluminium; silver mirrors are much more expensive than aluminium mirrors, and aluminium mirrors are low-cost and durable. That is, do not put bathrooms in dry places. When wearing mirrors are used, silver mirrors are generally sold for about 60-70 yuan/square metre and aluminium mirrors for about 40-60 yuan/square metre. In terms of brightness, the refractive performance of silver mirror is better than that of aluminium mirror. Under the same light intensity, silver mirror will appear brighter.
