Many people may hear about the special use of tempered glass, but not everyone knows what tempered glass is? Currently, tempered glass is applied a lot in buildings, commercial centers, hospitals, houses, ...
So what is tempered glass? What characteristics does it have that appeal and is so popular? Let's find out in this article with MOIVAONHATOI:
WHAT IS TEMPERED GLASS?
DEFINITIONS ON Tough glass
Only the name of tempered glass also indicates the ability to withstand the great external force of the glass, but if you know another name of tempered glass is tempered glass, you will easily imagine. What is tempered glass.
Tempered glass is ordinary glass tempered to 680-700 degrees Celsius and quickly cooled with cool air. The cooling process is accelerated to increase glass surface compression (increase hardness) to increase bearing capacity, impact resistance and better heat resistance. This tempering process will make the glass 4-5 times harder than ordinary heat-free glass.
As a result, tempered glass will be less likely to break due to temperature changes. Often broken glass will form many sharp and dangerous pieces. But tempered glass when broken will "crumb like corn", thus minimizing the damage of glass.
Tempered glass is so hard that if you hold a pestle (not an iron hammer) against the glass surface of a thickness of 12mm-19mm, it is almost impossible to break.
The surface stress of 12mm tempered glass is above 81 MPa (ie> 810 Bar). For ease of comparison, the back tire pressure is 2.5 Bar (often called 2.5 kg), while the surface stress of 12mm tempered glass is up to 810 Bar (300 times more).
ACKNOWLEDGMENT ABOUT POWER
You can see the edge of the tempered glass is always sharpened and rounded, not square like normal glass.
Another way you use a small hammer to tap the glass, tempered glass always has more echoes, but this method should not be tried because if too strong, it will easily break the whole sheet.

How are other glasses safe?
Laminated Glass: is made by gluing 2 or more layers of ordinary glass together. Between the 2 glass layers is a layer of PVB film. Thanks to these layers of film, when broken, these fragments are retained, not thrown out of danger. With different types of film can create many types of glass such as clear glass, tinted glass, reflective glass, ... Laminated glass after finishing can continue processing (cutting, drilling, grinding, ...) should have mass production possible.

WHAT ARE THE ADVANTAGES OF Tempered Glass?
- Tempered glass has high rigidity, impact resistance - good impact resistance, effective anti-vibration. With this outstanding feature, toughened glass is often used as glass walls office, glass façades for tall buildings, hydraulic doors, glass shower cabins, glass stair railings, ...
- Good sound insulation.
- Tempered glass is greatly appreciated compared to other building materials in the field of construction. It brings sophistication, elegance, modern professional style to the project.
- Safety, Reduce damage when broken: Tempered glass is difficult to break, only when subjected to impact or excessive heat pressure (many times compared to conventional glass), the new glass will break. When the glass breaks, it will be dispersed into small particles, sharp edges will be abraded and harmless. Users also do not have to worry about the fire escape problem because the glass is always equipped with the ability to escape.
- Resist sudden temperature change. Tempered glass features a very high temperature change suddenly, the temperature difference when changing can be up to 150oC without cracking. This is not possible with conventional glass (50 ° C).

What are the disadvantages of tough glasses?
- Although the case of natural glass breakage is very rare, it still gives users certain worries.
- Tempered glass is also glass, so it is clear and bright so it will quickly get dirty if not cleaned regularly.
- If using too much tempered glass in the room, it is easy to cause overexposure or greenhouse effect - over heat.
- Tempered glass cannot be reprocessed like normal glass, once shaped and tempered, the glass will retain its shape and cannot be chopped or resized. Edge grinding or drilling must be done before the tempering process begins.
With the above information, you probably better understand what tempered glass is, as well as know more about its characteristics. Read carefully the advantages and disadvantages of this type of glass to see if it really suits your house, or your company.
