What is the Difference Between Tempered Glass and Laminated Glass?

The difference between tempered glass and ordinary glass.

After the glass broken, the fragments will break into uniform small particles and there is no common sharp knife-shaped glass, which is called the safety glass and widely used in cars, interior decoration. The ordinary glass broken sharp knife-like sharp corners are easy to cut children or impactors, causing personal injury. After the glass is broken into small particles or knife. This is the main difference between tempered glass and ordinary glass. However, in engineering inspection, it is unrealistic to use such a destructive test at every turn. So how can you know what you buy is tempered glass or not? There has to be analyzed from the principle of tempered glass manufacturing. Tempered glass is obtained by cutting an ordinary annealed glass into the required size first, then heating it to a near softening point, and then performing rapid and uniform cooling. After tempering the glass surface to form a uniform compressive stress, while the internal tensile stress is formed, the performance of the glass can be greatly improved, the tensile strength is more than 3 times the latter, the impact resistance is more than 5 times the latter. It is also this feature, the stress characteristics of authenticity to become an important symbol of toughened glass, that is tempered glass can be seen through the polarizer in the glass edge of the color stripes, and in the glass surface observation, you can see the black and white White spots. Polarizer can be found in the camera lens or glasses, observe the adjustment of the light source, so that easier to observe. Laminated glass refers to the middle of the double-glazing sandwiched with a special gum, this approach glass after the safety factor higher than ordinary tempered glass. Most are used for high-rise building landscape balcony. It will not be broken after the balm drop but the whole piece of adhesive together, it is safe. The price slightly higher than the same thickness of ordinary tempered glass.
