Due to the breakage of the tempered glass, the shreds break into uniform small particles and there is no sharp corner of the ordinary glass knife, so that it is called safety glass and is widely used in automobiles and interiors. In the home, sharp sharp corners of ordinary glass can easily cut children or impactors and cause personal injury. After the glass is broken, it becomes a small particle or a knife. This is the main difference between tempered glass and ordinary glass. However, it is unrealistic to use this destructive test at any time during the inspection of the project. How can you know if you bought toughened glass? This has to be analyzed from the principle of tempered glass manufacturing. Normally annealed glass is cut to the required size, then heated to a near softening point, and rapidly and uniformly cooled. After the tempering treatment, uniform pressure is formed on the glass surface, and tension is formed inside the glass. The performance of the glass is greatly improved. The tensile strength is more than 3 times that of ordinary glass, and the impact resistance is more than 5 times that of ordinary glass. It is also this feature that tension characteristics have become an important indicator of the identification of true and false tempered glass, that is, tempered glass can see colored stripes on the edge of the glass through the polarizing plate, while the surface of the glass can observe black and white. Spots. The polarizer can be found in the camera lens or glasses. Observe the adjustment of the light source during observation so that it is easier to observe. The State clearly clarifies the indoor glass products such as bathroom partitions in the “Regulations for the Management of Architectural Safety Glassâ€: Safety glass must be used. All aluminum alloy doors use tempered glass. The “3C certification†logo is printed on the front of the glass to ensure the safety and reliability of aluminum alloy doors.
