Tempered glass belongs to safety glass. Tempered glass is actually a kind of prestressed glass, in order to improve the strength of glass, usually use chemical or physical methods, the formation of compressive stress on the surface of glass, glass under external force first offset surface stress, so as to improve the bearing capacity, enhance the glass itself resistance to wind pressure, heat and cold, impact, etc. So, Widely used in high-rise building doors and Windows, glass curtain walls, indoor partition glass, lighting ceiling, sightseeing elevator passage, furniture, glass guardrail, etc
Advantage
The first is the strength compared with ordinary glass several times, bending resistance.
The second is the use of safety, the increase of its carrying capacity has improved the fragile quality, even if the tempered glass damage is also small pieces without acute Angle, the harm to the human body is greatly reduced. Compared with ordinary glass, tempered glass has 3~5 times of rapid cooling and rapid heating properties, generally can withstand temperature difference of more than 250 degrees, to prevent thermal cracking has obvious effect. It's one of the safety glasses. To guarantee the safety of high-rise buildings to provide qualified materials.
character | Tempered glass | Semi-tempered glass | Common glass |
safety | best | ordinary | no |
intension | 150Mpa | 100 - 120Mpa | 30 - 90Mpa |
heat endurance | 250 - 320℃ | 100℃ | 2-100℃ |
quadric stress | 95Mpa | 24-69Mpa | ...... |
Broken state | Obtuse-angle grain | Radioactive crushing | Sharp sheet |
Self-Destruct | yes | Basically Never | No |
Tempered glass is divided into plane tempered glass and curved tempered glass according to its shape. Generally plane tempered glass thickness of 11, 12, 15, 19mm and so on twelve kinds; Curved tempered glass thickness has 11, 15, 19mm and other eight kinds, the specific thickness after processing or depends on the manufacturer's equipment and technology. But curved tempered glass has a maximum radian limit for each thickness.
Degree of toughening
Tempered glass: tempered =2~4N/cm, glass curtain wall tempered glass surface stress α≥95Mpa;
The semi tempered glass: tempered =2N/cm, glass curtain wall semi tempered glass surface stress 24Mpa≤α≤69Mpa;
Super toughened glass: degree of toughening > 4N/cm.
