TEMPERED GLASS
Tempered Glass is produced by heating annealed glass in a furnace to approximate softening point then cool the glass quickly and uniformly by blow cool air onto its surface. Uniform compressive stress is formed on its surface, while tensile stress is formed inside, Therefore, it is more resistant to thermal breakage and is capable of withstanding higher wind loads and impact.
HEAT STRENGTHENED GLASS
The process of Heat Strengthening is similar to that of temped glass, however, in this instance the glass is quenched at a slower rate. The result is the glass tension is less than that of the tempered Glass.
STANDARDS
Comply with GB/T 17841 for Coating Glass Standard
Comply with BS EN 1863 European Standard
Comply with ASTM C 1048-18 American Professional Association standards
TEMPERED GLASS FEATURE
Safety: when broken, it will break into obtuse small particles, which is difficultly hurt people.
High strength: the strength of tempered glass is 4 times that of anneal glass.
Thermal stability: withstanding 200°C temperature difference at least.
HEAT STRENGTHENED GLASS FEATURE
It is obviously superior to ordinary annealed glass in mechanical strength, wind pressure resistance, impact resistance and thermal shock resistance
Low probability of spontaneous break
Better flatness than tempered glass
Non-safety glass
