[China Glass Net] Since the tempered glass is broken, the pieces are broken into uniform small particles and have no sharp angles like ordinary glass knives. They are called safety glass and are widely used in automobiles and interior decoration. In the home, the sharp knives and sharp corners of the ordinary glass are easy to cut children or impacters, causing personal injury. After the glass is broken, it becomes a small particle or Knife-like is the main difference between tempered glass and ordinary glass. However, in engineering inspections, it is unrealistic to use such destructive tests. So how can you know if you are buying tempered glass? This has to be analyzed from the principle of tempered glass. The tempered glass is obtained by first cutting the ordinary annealed glass into the required size, then heating it to a near softening point, and then performing rapid and uniform cooling. After the tempering treatment, the surface of the glass forms a uniform pressure, while the inside forms a tension, which greatly improves the performance of the glass. The tensile strength is more than three times that of ordinary glass, and the impact resistance is more than five times that of ordinary glass. It is also this feature that the tension characteristic becomes 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 polarizing plate, while black and white can be seen on the surface of the glass. Spots. Polarizers can be found in camera lenses or glasses, and attention is paid to the adjustment of the light source during viewing, which makes it easier to observe.
