What are the advantages and disadvantages of tempered glass?

1. What is tempered glass and what is its principle?

Tempered glass is a kind of strengthened glass. Through physical and chemical treatment methods, the compression and impact resistance of ordinary glass are enhanced.

The principle of tempered glass: through complex tempering treatment, a compressive stress is formed on the surface of the glass. When the glass is subjected to external force, the surface stress will offset part of the external force, so that the external force on the glass itself is weakened, thereby achieving an increase in bearing capacity.

2. What are the advantages of tempered glass?

1. Higher strength

Tempered glass has higher strength. Compared with ordinary glass, its bending strength and impact resistance are enhanced by several times or even 10 times.

2. Higher safety

The increased bearing capacity of tempered glass also improves the disadvantage of glass being fragile. Even if it is destroyed, the fragments of tempered glass are in a state without sharp angles, which greatly reduces the possibility of injury. In addition, tempered glass is resistant to rapid cooling and heating, and can withstand large temperature changes.

3. What are the disadvantages of tempered glass?

1. After tempering, it cannot be processed again

Tempered glass has integrity and cannot be processed or cut again. Therefore, before tempering, the glass needs to be processed into the required shape.

2. There is a possibility of self-explosion

In an environment with large temperature differences, due to the principle of thermal expansion and contraction, tempered glass may explode, so there are certain requirements for the environment in which it is used.

Simply put, the principle of tempered glass is the principle of mechanics. After special treatment, a compressive stress is generated on the surface of the glass to offset part of the external force to achieve the effect of reducing the impact force on the glass itself. Compared with ordinary glass, tempered glass is stronger and safer, but it cannot be processed again and there is also the phenomenon of self-explosion.
