What is the principle of tempered glass?

Tempered glass is a type of reinforced glass that has undergone tempering treatment. Its principle is to form a compressive stress on the surface of the glass, which is used to counteract some external forces. Advantages: 1. Higher strength; 2. Higher security. Disadvantages: 1. It cannot be processed again after tempering treatment; 2. There is a possibility of self explosion.
1、 What is tempered glass and its principle?
Tempered glass is a type of reinforced glass that enhances the compressive and impact resistance of ordinary glass through physical and chemical treatment methods.
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 forces, the surface stress will offset some of the external forces, weakening the external forces on the glass itself, thereby improving its load-bearing capacity.

2、 What are the advantages of tempered glass?
1. Higher strength
Tempered glass has higher strength. Compared with ordinary glass, its Flexural strength and impact strength have been increased several times or even 10 times.
2. Higher security
The increase in load-bearing capacity of tempered glass also improves the fragility of glass. Even if it is destroyed, the fragments of tempered glass remain in a non sharp angle state, greatly reducing the possibility of injury. In addition, tempered glass is resistant to rapid cooling and heating, and can resist significant temperature differences.

3、 What are the drawbacks of tempered glass?
1. No further processing after tempering treatment
Tempered glass has integrity and cannot be further processed or cut. Therefore, before tempering, it is necessary to first process the glass into the required shape.
2. There is a possibility of self explosion
In the environment with large temperature difference, due to the principle of Thermal expansion, tempered glass may self explode, so there are certain requirements for the use environment.
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, which is used to counteract some external forces and achieve the effect of reducing the impact force on the glass itself. Compared with ordinary glass, tempered glass has higher strength and safety, but it cannot be further processed and there is also a phenomenon of self explosion.
