(Summary description)Tempered glass belongs to safety glass. Tempered glass is actually 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 glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the resistance of the glass itself. Wind pressure, cold and heat, shock, etc. Pay attention to distinguish it from FRP. Flat tempered and bent tempered glass belong to safety glass. Widely used in high-rise building doors and windows, glass curtain walls, indoor partition glass, daylighting ceilings, sightseeing elevator channels, furniture, glass guardrails, etc. After the toughened glass is broken, the fragments will be broken into uniform small particles and there is no common glass knife-shaped sharp corner, so it is called safety glass and is widely used in automobiles, interior decoration, and windows that open to the outside on high floors.

ZhuoGao glass manufacturer teaches you how to distinguish qualified tempered glass?
1. Dimensions and allowable deviations: According to the difference in side length and thickness of the glass, the allowable errors in side length, diagonal line, hole position, and hole size are respectively specified.
2. Allowable deviation of thickness: According to the difference of glass thickness, the allowable deviation of each medium thickness glass is specified, for example: the allowable deviation of the thickness of 12mm tempered glass is +-0.4mm.
3. Appearance quality: Appearance quality clearly stipulates the number of edges, scratches, clamp marks, cracks, and missing corners of tempered glass.
4. Curvature: The curvature of flat tempered glass should not exceed 0.3% when it is bowed, and it should not exceed 0.2% when it is corrugated.
5. Impact resistance: Take 6 pieces of tempered glass for experiment, and the sample is qualified if the damage is not more than 1 piece.
6. Fragment status: There are clear requirements for the number of fragments in any 50X50mm area of each tempered sample, and no fragments longer than 75mm are allowed. Example: 4~12mm tempered glass reduces the number of fragments to 40 pieces.
7. Shot bag impact performance: The sample will not be damaged when the drop height of the bullet bag is 1200mm.
8. Surface stress: The surface stress of tempered glass is not less than 90MPa.
9. Thermal shock resistance: toughened glass is resistant to 200 degrees Celsius temperature difference without being damaged.
