| The horizontal toughened glass is one kind of security glass, heats up the glass to 700 about, causes its surface to form compression stress, but after in its superficial even quenching. According to processes the degree the difference, also may divide into the entire toughened glass and half toughened glass. Half toughened glass collides the broken after fragment from outside and the ordinary annealed glass is similar, but the coefficient of strength is ordinary annealed glass 2 times. In under the same thickness condition, the entire toughened glass surface anti- impact intensity ordinary annealed glass is higher than 5 times. The toughened glass characteristic is: The high anti- impact causes it not to be easy brokenly, also is not easy harming body; Good resists heat the sudden change enables it to resist 200 temperature differences. |
