Advantages and disadvantages of tempered glass

1. Safety: When the tempered glass is damaged by external force, the debris will become a honeycomb-like obtuse-angled small particle, which is not easy to cause serious damage to the human body.


2. High strength: The impact strength of tempered glass of the same thickness is 3 to 5 times that of ordinary glass, and the bending strength is 3 to 5 times that of ordinary glass.


3, thermal stability: has good thermal stability, can withstand the temperature difference is 3 times that of ordinary glass, can withstand temperature changes of 280 ~ 320 °C.


Tempered glass advantages

The first is that the strength is several times higher than that of ordinary glass and it is resistant to bending.

The second is safe use, and its load-bearing capacity is improved to improve the fragile nature. Even if the tempered glass is broken, it is a small piece with no sharp angle, and the damage to the human body is greatly reduced. The tempering resistance of tempered glass is 3 to 5 times higher than that of ordinary glass. Generally, it can withstand temperature changes of more than 250 degrees, which has obvious effects on preventing thermal cracking. It is one of the safety glasses. To ensure the safety of qualified materials for high-rise buildings.


Tempered glass defects


1. The tempered glass can no longer be cut and processed, and the glass can only be processed to the required shape before tempering, and then tempered.

2. Although the strength of tempered glass is stronger than that of ordinary glass, tempered glass has the possibility of self-explosion (self-rupture), while ordinary glass does not have the possibility of self-explosion.

3. The surface of the tempered glass will have unevenness (wind spots) and a slight thickness will become thin. The reason for the thinning is that after the glass is melted by hot melt, it is rapidly cooled by a strong wind force, so that the internal crystal gap of the glass becomes small and the pressure becomes large, so the glass is thinner after tempering than before tempering. Under normal circumstances, 4-6MM glass is thinned 0.2-0.8MM after tempering, and 8-20MM glass is thinned by 0.9-1.8MM after tempering. The degree of specificity depends on the equipment, which is why tempered glass cannot be mirrored.

4. The flat glass used for construction after passing through the tempering furnace (physical tempering) is generally deformed, and the degree of deformation is determined by the process of equipment and technicians. To a certain extent, it affects the decorative effect (except for special needs).
