tempered building glass

Tempered glass 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. 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-resistant srength: Impact-resistant strength of tempered glass is 3-5 times higher than that of float glass of the same thickness. Thermal stability : Thermal stability of tempered glass is 3 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 can offset due to opposite stress direction. When tempered glass is heated extremely, compressive stress is generated 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. Application Tempered glass is safty glass, extensively applied in the places which has critical request of high mechenical strength and safety, such as glass door, curtain wall of building, indoor partition, elevator,showcase, door and window of building, furniture and household appliance etc. Types of Product: clear, tinted, color glazed,heat-reflective coated, Low-E, IGU and laminated glass etc. Color: clear, ultra-white, various green, blue,grey and brown.
