Tempered Glass Characteristics And Disadvantages Of Tempered Glass
May 24, 2017

Tempered Glass Toughened glass characteristics of the advantages and disadvantages of tempered glass surface with a compressive stress glass. Also known as tempered glass. The glass was reinforced by the steel method, which began in France in 1874.

  Tempered glass belongs to safety glass. In fact, the use of chemical or physical methods, the formation of compressive stress on the glass surface, the glass bear the external force when the first to offset the surface stress, thereby enhancing the carrying capacity, enhance the glass self-resistance Wind pressure, cold and heat, impact and so on. Note that it is distinguished from fiberglass

  safety

  Tempered Glass When the glass by external damage, the debris will be similar to the honeycomb obtuse broken small particles, not easy to cause serious harm to the human body.

  high strength

  The same thickness of the tempered glass impact strength is 3 to 5 times the ordinary glass, bending strength is 3 to 5 times the ordinary glass.

  Thermal stability

  Tempered glass has good thermal stability, can withstand the temperature difference is 3 times the ordinary glass, can withstand 300 ℃ temperature difference.

  advantage

  Tempered Glass The first is the strength than ordinary glass to improve several times, bending.

  The second is the use of safety, its carrying capacity increased to improve the fragile nature, even if the destruction of tempered glass was no small angle of small pieces, the damage to the human body greatly reduced. Tempered quenching and cooling properties of tempered glass than ordinary glass has 3 to 5 times the increase, generally can withstand more than 250 degrees of temperature changes, to prevent the thermal cracking has a significant effect. Is a kind of safety glass. For the protection of high-rise buildings to provide qualified materials for security.

  Disadvantages

  Tempered glass defects:

  1. The tempered glass can no longer be cut, and processed, only in the steel before the processing of the required shape to the glass, and then steel processing.

  Although the strength of tempered glass is stronger than that of ordinary glass, but the tempered glass has blew its own rupture, and there is no possibility that ordinary glass is blew.

  3. Tempered Glass The surface of the tempered glass will be uneven (wind spot), with a slight thickness thinning. The reason for the thinning is because the glass in the hot melt softening, after a strong wind to make it quickly cooling, so that the glass inside the crystal gap becomes smaller, the pressure becomes larger, so the glass after the steel than in the steel before the thin. Under normal circumstances 4 ~ 6mm glass in the steel after thinning 0.2 ~ 0.8mm, 8 ~ 20mm glass in the steel after the thinning 0.9 ~ 1.8mm. The specific extent to be determined according to the equipment, which is tempered glass can not do the mirror of the reasons.

  4. Through the steel furnace (physical steel) after the construction of flat glass, there will be a deformation, the degree of deformation by the equipment and technical staff process
