How to identify the authenticity of toughened glass? What color does toughened glass 3C mark?

Glass is only transparent, but also has high strength hardness. It is an indispensable material in daily production life. There are many kinds of glass, in addition to the common float glass toughened glass, there are also hot-melt glass, laminated glass, frosted glass other varieties with special properties. Want to know how to determine the authenticity of toughened glass what color the 3C mark of toughened glass is, read the article shared by Lanzhou toughened glass manufacturer.

1、 How to determine the authenticity of toughened glass

Toughened glass is obtained by cutting ordinary annealed glass into required size, then heating it to near softening point, cooling it quickly evenly. After toughening, the surface of the glass forms uniform compressive stress, while the interior forms tensile stress, which greatly improves the performance of the glass. The tensile strength is more than three times of the latter, the impact resistance is more than five times of the latter.

It is also this feature that the stress feature becomes an important mark to identify the true false tempered glass, that is, the tempered glass can see color stripes at the edge of the glass through the polarized light sheet, the black white spots can be seen on the surface layer of the glass. Polarizer can be found in camera lens glasses. Pay attention to the adjustment of light source when observing, so it is easier to observe.

Each toughened glass has a 3C certification mark, which can also be used as a standard to judge whether it is toughened glass.

2、 What color does toughened glass 3C mark

3C logo color is important.

Since the tempered glass cannot be cut reprocessed after being fired, the ink is screen printed on the glass surface to form words patterns before the glass is toughened, then the ink glass are combined after high temperature sintering. Therefore, when the "3C mark" is seen in the purchase of doors windows, it can be scraped, The normal 3C mark can't be scratched off the original factory. If it can be scratched scratched off by hand, it can be concluded that it's fake toughened glass

In addition to the 3C mark, there must be a serial number below, which is a random code that will be repeated. Each random code has corresponding manufacturers products. When the certification mark distribution management center issues the compulsory product certification mark, the products corresponding to the code have been input into the computer database, consumers can code query on the national 3C certification network according to the number, Confirm the manufacturer.

Generally speaking, the door window glass with 3C mark is basically toughened glass, but we should be clear that 3C mark is a quality mark, it is just a basic safety certification, that is to say, if we can't see the 3C mark on the door window glass, we will be sure that the quality of the product will be a problem, so we don't pay attention to the use, For safety.

3C, China Compulsory Certification, English Name: China Compulsory Certification, English abbreviation: CCC. The full name of 3C certification is "China Compulsory Product Certification". It is a product conformity assessment system implemented by our government in accordance with laws regulations to protect the personal safety national security of consumers, strengthen product quality management.
