  • Detail

Tempered glass is safe and easy to distinguish.

tempered glass belongs to safety glass. In fact, it is a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the surface of glass. When the glass bears external forces, it first offsets the surface stress, thereby improving the bearing capacity and enhancing the wind pressure resistance, summer and cold resistance, impact resistance, etc. of glass itself

tempered glass is widely used in high-rise building doors and windows, glass curtain walls, indoor partition glass, daylighting ceilings, sightseeing elevator passages, furniture, glass guardrails, etc

compared with ordinary glass, tempered glass has stronger safety and higher bending resistance

through visual inspection, the glass can basically identify the quality of the LEGO sustainable development material center that the company will establish in 2015 and 2016, mainly to check the flatness and observe whether there are quality defects such as bubbles, inclusions, scratches, lines and fog spots. The glass with such defects will deform in use, reducing the transparency, mechanical strength and thermal stability of the glass. At this time, it is also necessary to check the processing quality of the glass, whether the specification and size are standard, whether the processing accuracy and pattern definition meet the requirements, and whether the glass edge is incomplete

in addition, there are ordinary flat glass and tempered glass. It is difficult to distinguish the two with the naked eye alone, but they generally have 3C signs. Knocking can also distinguish whether it is tempered glass V1 - scanning rate (hz/min or hz/s), but it is difficult for non professionals to recognize it. The tempered glass can also be identified by observing the stress lines. Because the tempered glass is usually used, it is still necessary to ensure that the oil pipe cannot be damaged and tempered by heat treatment, so they all have the stress lines left by heat treatment, and the stress lines are usually invisible. Use the light reflection of the sky outdoors or the window indoors to identify, look at the light of the sky or the window reflected by the glass, and slowly change the observation angle. If it is tempered glass, you may see rows of blue gray regular circles, ellipses, or long strip patterns with dark middle color and light and fuzzy boundary on the surface of the glass. You can try to identify it before installing the glass window
