Tempered Glass Processing

Jun. 30, 2017

Tempered glass(also called toughened glass,full tempered glass,shorten called FT)is a type of glass with even compressive stress on the surface which is made by heating float glass to nearly softening point and then cooling it down rapidy by air .During the instant cooling process, the exterior of glass is solidified due to rapid cooling while the interior of glass is cooled down relatively slowly .This process will bring the glass surface compressive stress and the interior tensile stress which can improve the mechanical strength of glass by gemination and result in good thermal stability.

Tempered glass is a glass which has been treated by a process of controlled heating and cooling in order to achieve a much higher mechanical and thermal resistance - up to 4-5 times more than the normal glass.

Furthermore for the security and safety features of tempered glass helps the fact that in case of an eventual breakage the glass breaks into small safe pieces.


Our tempered glass meets the requirements of the adopted in European standard EN 12150-1 - "Building glass. Thermally toughened soda lime silicate safety glass.“, on the basis of which you can obtain a certificate of conformity.

Our tempering line has the following characteristics:

· Tempering of flat glass – 3mm-25mm

· Tempering and bending of glass – 5mm-19mm

· Semi-tempering of glass – 4mm-8mm

· Maximum size for flat glass – 2400mm/4200mm.

· Maximum size for bent glass – 2400mm/5000mm.

Possibility for tempering patterned, tinted, reflective and low-e glasses with all available coatings on the market.

Feature 

Safety: Glass is not easy to be broken when attacked.Broken glass particle is of honeycomb shape with obtuse angles which won't cause severe hurt to human body.

High mechenical-resisitant srength:Impact-resistant strength of tempered glass is 3-5 times higher than that of float glass of the same thickness. Tempered glass can withstand sudden tenperature shift of 220℃-250℃ while float glass can only withstand shift of 70℃-100℃.When tempered glass suffers rapid cooling of a certain extent.

the internal tensile stress and compressive stress on the surface of glass which is as double as tensile stress. Therefore.tempered glass also can withstand certain level of rapid heating up.



Good flexibility:Deflection angle of  tempered glass is 3-4 times larger than that of float glass of the same thickness

.When there is load on tempered glass ,its maximum tensile stress does not located on the glass surface as float glass ,but on the central point of glass sheet.
