Tempered glass - G-T-003

Tempered glass is that heat float glass to conversion temperature, then cool evenly , so make the glass surface with strong stress, during the cooling course, the glass surface is quick cooling and then solidified, instead the glass inner-part continue to cool & contract to make glass surface produce stress and inner part produce tension power, so improve the strength and anti-heat stability
Higher anti-heat property: can bear 300?? temperature, have obvious effect for preventing from heat-cracking

Higher Bearing pressure: the property to easy break can be got improved, when tempered glass broken, will take on obtuse angel broken piece, can greatest reduce the harm for human body
Higher Strength: anti-bent glass is 3-5 times of common glass, anti-compact power is 5-10 times of common glass

Safety property Tempered Semi-tempered Common glass
safety best Common no
strength 152MPA -------- 30-90MPA
Heat stability 250-320 100 20-100
Surface stress 95MPA 24-69MPA ----------
Broken state obtuse particle Radiation broken Sharp angle

property
Heat stability: can bear high temperature, about is 3 times of common glass, can endure 200-300 degree temperature change
High strength: the strength of tempered glass is about 4-5 times of common glass
Safety: when glass is destroyed by outer force, will become small particle at obtuse angle, greatest reduce the harm for human body
Standard: confirm to GB15763.2(tempered glass) nation standard, passed China CCC safety glass certificate
specification
Thickness: 4-19mm
Min size: 300*200mm
Max size: 2400*4800mm
Applicable range: tempered glass is a kind safety glass, widely used for these place with higher mechanical strength and higher safety property , for example, glass curtain wall, advanced kitchen window, shower house, auto handrail, balcony door & window, glass partition, gym, etc.
Package: packed in container or wooden box, each piece glass is packed in plastic bag & paper bag, the gap between glass and package box should use light & soft filling material that not easy cause to scratch, requirement should confirm to JC/T 512 Rule

Feature
Once crack, the crackle flaw will extend to edge, its broken pieces will keep within the frame, not fall down
Mechanical strength is 2 times of common glass
Can effectively resist heat-stress action, avoid heat-crack
Not easy to happen explosion phenomenon
With better flatness compared with tempered glass
Semi-tempered glass
Also called heat strengthen glass, the production craftwork is similar to tempered glass, just the cooling speed is a little slow, its surface stress is a litter smaller than tempered glass, so it is not safety glass
