|The composition of the mobile phone glass is not much different from that of ordinary glass, except that the content of the glass silica of the mobile phone is higher and the melting temperature is higher. The main difference between them is the post-processing process. After ordinary glass is melted, it can be annealed (the thickness can be less than 2mm without annealing), otherwise it will be easy to burst. After the mobile phone glass is melted, it is not thinned because it is very thin. It will not burst. However, in order to achieve high strength, it is difficult to produce ultra-thin cell phone glass tempering process through tempering process. The reason is that it is too thin and it is difficult to generate strong stress, so the process is special.
In addition to physical tempering, a few high-end mobile phone glass will be chemically tempered to achieve high strength. In addition, in order to improve the mobile phoneglassHardness and scratch resistance, high-end mobile phone glass will also be coated on the surface, such as a layer of Al2O3 (Al2O3), Mohs hardness can reach 9 (Al2O is the main component of red sapphire), so also Called sapphire glass. Other coatings, such as oil resistant coatings, conductive coatings, etc., are independent of the glass itself and are related to the needs of the phone.
