The principle of tempered glass cover technology: By heating and rapidly cooling the glass, the surface of the glass presents uniform compressive stress and the interior presents uniform tensile stress, thereby improving the flexibility and increasing the strength of the glass several times. Figuratively speaking, the upper and lower surfaces of tempered glass are like a spring net that shortens towards the center, while the inner central layer is like a spring net that stretches outwards. When the glass bends, the spring on the outer surface is stretched open, allowing it to bend a larger arc without breaking. This is the source of toughness and strength.

The shapes of tempered glass are different, but the common ones are still flat and curved. Tempered glass has relatively high safety compared to other types of glass, but the tempered glass we use may exhibit poor flatness,Tempered glass coverWhat are the reasons for the poor flatness of tempered glass?

When tempered glass is heated, the temperature difference between the upper and lower surfaces of the tempered glass will cause deformation, resulting in upward or downward bending. Different treatments should be taken according to different situations.

2. Uneven random temperature distribution can also cause deformation of tempered glass. Tempered glass manufacturers tell everyone that this is mainly due to poor equipment condition.

When heating tempered glass, there is a temperature difference between the center and the edges, which can also cause deformation of the tempered glass. The reason is that the temperature in the center is higher than that in the edges, resulting in unevenness during cooling.
