Tempered glass

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
