Toughened glass is also known as tempered glass. It is a glass obtained by heating ordinary glass to a softening point and quenching treatment. The surface has a strong and uniform compressive stress and the mechanical strength is multiplied. Compared with ordinary glass of the same thickness, the tempered glass is resistant to bending and impact. Three to five times higher, the ability to resist drastic changes in temperature is three times higher. Tempered glass has good safety and is granulated after being broken, thus avoiding possible damage to the human body. It is widely used in high-rise building curtain walls, indoor glass partitions, elevator handrails and other places where safety is required. The disadvantage of the tempered glass stage is relatively heavy. The use of tempered glass is not suitable for 18MM thick. Generally, the thickness of 15MM is enough to meet the bearing requirements of the performance. Too thick will only increase the burden of transportation and manual handling.
Tempered glass is a safety glass. Tempered glass is actually a type of prestressed glass. In order to increase 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, the surface stress is first offset, thereby improving the bearing capacity and enhancing the resistance of the glass itself. Wind pressure, cold and heat, impact and so on. The main advantages of tempered glass are two: the strength is several times higher than that of ordinary glass, the bending strength is 3--5 times that of ordinary glass, and the impact strength is 5--10 times that of ordinary glass, which improves the strength.safety. Safe to use, its load-bearing capacity is improved and the fragile property is improved. Even if the tempered glass breaks down, it will show small fragments without sharp angles, and the damage to the human body is greatly reduced. The quenching and rapid heat-heating properties of tempered glass are 2 - compared with ordinary glass. -3 times improvement, generally can withstand temperature changes above 150LC, has a significant effect on preventing thermal cracking.
