What Is The Density of Tempered Glass?
In order to ensure our personal safety, tempered glass is used on the windows of some cars and trains, and some buildings are also tempered. So do you know why tempered glass is used in these places? How does it ensure our safety? Under normal circumstances, toughened glass is heavier, so its density is relatively large, it is more resistant to pressure, and will not produce sharper fragments when it is broken, thus protecting us. Since tempered glass is heavy, what is its density? Let us take a closer look.
Tempered glass is a kind of safety glass that can play a protective role. It is processed by physical methods to improve the strength of the glass, so that the finished tempered glass can withstand great impact. Before the production of Shenzhen glass, it needs to make a fixed size in advance, and then after different times and different degrees of high temperature, tempered glass of different thickness is formed. When we pick up the tempered glass, we will find that it is very heavy, so it has a high density.
The density of tempered glass is about 2500 kg/m3. If you compare it with the density of steel, its density can reach 1/3 of that of steel. The density of toughened glass is mainly related to its manufacturing process. Ordinary annealed glass undergoes high temperature treatment for a period of time to make its surface soft and liquefied. At the same time, the surface of the glass is blown and cooled. While heating and cooling, the surface of the tempered glass is in a compressed state. , Thereby changing the tension and strength of the glass. In fact, the density of tempered glass is the same as that of ordinary annealed glass, but because of the process of heating and cooling, the internal force is more
