The difference between tempered glass and ordinary glass
Because the strength of the tempered glass is relatively high, and the fracture is broken, the pieces break into uniform small particles and have no sharp angles like a common glass knife. Therefore, it is called safety glass and is widely used in interior decoration. Migo Glass In the front of the home glass, the production of round coffee table, round table top, partition, bathroom wall and so on.
Generally, when the ordinary glass is broken, the sharp knife-like sharp corner is easy to cut the child or hit, causing damage to the human body. After the glass is broken, it becomes a small particle or a knife. This is the most important difference between tempered glass and ordinary glass. However, in engineering inspections, it is unrealistic to use such destructive tests. How can we know if we 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 tempering, the surface of the glass forms a uniform compressive stress, while the inside forms a tensile stress, which greatly improves the performance of the glass. The tensile strength is more than three times that of the latter, and the impact resistance is more than five times that of the latter. It is also this feature that the stress characteristic is an important sign to identify tempered glass, that is, tempered glass can see the colored stripes on the edge of the glass through the polarizing plate, while the black and white can be seen in the surface layer of the glass. spot. Polarizers can be found in camera lenses or glasses, and attention is paid to the adjustment of the light source during viewing, which makes adjustment easier. If you have any needs, you can find Migo Glass.
