Information
Toughened glass has a wide range of scenes in daily life. We can see the figure of toughened glass in both the construction field and electronic equipment and instruments. I believe many friends are also very curious about how tempered glass is made. Today, let's reveal how toughened glass is made.
In fact, tempered glass is made of ordinary glass after high-temperature heating in the tempering furnace. The prestress on the surface becomes more homogeneous, which strengthens the impact force and resistance of the glass, and the strength is 3-5 times that of ordinary glass. The methods of making tempered glass mainly include physical tempering method and chemical tempering method. Let's take a look at these two methods.
Physical tempering method: the production method of heating the glass close to the softening temperature of the glass, and then blowing air on both sides to cool it rapidly, so as to increase the mechanical strength and thermal stability of the glass.
Chemical tempering method: change the surface composition of glass by chemical method to increase the surface lamination stress, so as to increase the mechanical strength and thermal stability of glass. It is also called ion exchange enhancement method because it strengthens glass through ion exchange.
Generally speaking, the hardness of glass processed by physical tempering method is stronger than that of chemical tempering method, but the above two methods should also be selected according to the thickness you choose. Different thicknesses will require different requirements. For example, glass with a thickness of more than 3mm can adopt physical tempering method, and if it is too thin, it can only be chemical tempering method.
