Tempered glass/Reinforced glass is safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, it first offsets the surface stress, thereby improving the bearing capacity and enhancing the resistance of the glass itself. Wind pressure, cold and heat, impact, etc. Pay attention to distinguish it from glass fiber reinforced plastic.
Tempered glass is obtained by first cutting ordinary annealed glass to the required size, then heating it to about 700 degrees close to the softening point, and then rapidly and uniformly cooling it (usually 5-6MM glass is heated at 700 degrees for about 240 seconds, Cool down for about 150 seconds. 8-10MM glass is heated for about 500 seconds at a high temperature of 700 degrees, and cooled for about 300 seconds. In short, according to the thickness of the glass, the time for heating and cooling is also different). After tempering, uniform compressive stress is formed on the surface of the glass, while tensile stress is formed inside, which improves the bending and impact strength of the glass, and its strength is about four times that of ordinary annealed glass. The tempered glass that has been tempered cannot be cut, ground, etc. or damaged, otherwise it will be "shattered" due to the destruction of the uniform compressive stress balance.
advantage:
1. The strength is several times higher than that of ordinary glass, and it is resistant to bending.
2. It is safe to use, and its carrying capacity is increased to improve the fragile nature. Even if the tempered glass is damaged, it will be small fragments without acute angles, which greatly reduces the damage to the human body. Compared with ordinary glass, the resistance to rapid cooling and rapid heating of tempered glass is improved by 3 to 5 times. It is a type of safety glass. To ensure the safety of qualified materials for high-rise buildings.
