        Tempered glass:


        Tempered glass also be called toughened glass, it is a kind of safe glass. It is a type of glass with even compressive stress on the surface which is made by heating float glass to nearly softening point (600-650°),Then cooling it down rapidly in glass surface. During the instant cooling process, the exterior of glass is solidified ,while the interior of the glass is cooled down relatively slowly. The process will bring the glass surface compressive stress and the interior tensile stress which can improve the mechanical strength of glass by germination and result in good thermal stability.

        Advantages of tempered glass:

        1)High intensity:The strength is 4-5 times of ordinary annealed glass in same thickness;

        2)High thermostability:Tempered glass can withstand the large temperature difference(200℃), the thermostability is 3 times of ordinary annealed glass;

        3)High safety:Once breakage occurs, the glass breaks into small cubical fragments, which are relatively harmless to human body.
