How Thermal Process Tempered Glass?

How Thermal Process Tempered Glass You Should Know

Tempering is a heat or chemical treatment in order to compress the surface of the glass layer so as to improve their resistance to breakage. The method comprises heating the glass to approximately 600 ° and then rapidly cooled. If defective, the stored energy is released in the form of the surface energy; That is why, if it is broken, breaks up into small blunt fragments do great damage. Although the heat treatment, color, clarity, chemical composition and the glass light transmission characteristics remain unchanged. Obvious changes are tensile strength and improved resistance to thermal stresses and thermal shock.

The thermal annealing glass is advantageous for the following reasons:


Strength is a key advantage. Glass, such as glass are known typically 4 to 5 times stronger than annealed glass and twice as strong as the TVG thickness, size and the like of the article.


When broken, glass breaks into relatively small pieces so the risk of serious injury as compared to conventional glass to reduce.

Thermal rupture:

Usually exposed directly to the glass surface sunlight heats the fastest, while the edges are relatively cooler. This creates temperature differences within the glass and the chances of thermal breakage. But a fully tempered glass has increased the margin opportunities to resist thermal breakdown strength.

Resistance border:

Increased the glass edge strength as compared with the normal offers designers the flexibility to use it in the glass spider and glasses fixed point.

Tempered glass application

The automotive industry uses glass for windshields, side windows, back windows and sunroofs in some cars. Inside it is for display cases, shelves, partitions, shower enclosures, shower doors, interior doors, toilets and more used.

The computer screens are made of glass.
