In the home, the sharp knife-shaped corners of ordinary glass broken can easily cut children or hit persons, causing personal injury. Whether the glass breaks into small particles or a knife shape is the main difference between tempered glass and ordinary glass. But in engineering inspections, it is undoubtedly unrealistic to use such destructive inspections at all times.
How to distinguish tempered glass:
Tempered glass is obtained by cutting ordinary annealed glass to the required size, then heating it to a near softening point, and then performing rapid and uniform cooling. After tempering, uniform compressive stress is formed on the surface of the glass, and tensile stress is formed inside, which greatly improves the performance of the glass. The tensile strength is more than 3 times that of the latter, and the impact resistance is more than 5 times that of the latter.
It is also because of this characteristic that the stress characteristic has become an important sign to distinguish true and false tempered glass, that is, tempered glass can see colored stripes on the edge of the glass through the polarizer, and black and white can be seen on the surface of the glass. Alternate spots. The polarizer can be found in the camera lens or glasses. Pay attention to the adjustment of the light source when observing, so that it is easier to observe.
