The Weakness of Tempered Glass

Fistly,where is the tempered glass weak?

The middle part of the tempered glass is the strongest, and the corners and edges are the weakest. In case of emergency, you can break the tempered glass to escape. The best way is to use a safety hammer or other sharp hard block to beat the edge and corners of the glass, especially the middle of the top edge of the glass, once the glass has a crack, it is easy to smash the whole glass.

Secondly, what are the advantages and disadvantages of tempered glass?

Advantages:

1, high strength: the mechanical strength, impact resistance and bending strength of tempered glass can reach 4-5 times that of ordinary glass.

2, high thermal stability: tempered glass can withstand a huge temperature difference without damage, resistance to temperature change is the same thickness of ordinary float glass 3 times. It can withstand the temperature difference of 150℃, and has obvious effect on preventing thermal cracking.

3, high safety: After the tempered glass is damaged by strong force, it quickly presents small obtuse particles, thus ensuring personal safety to the maximum extent. Application: Furniture, electronic and electrical industry, construction, decoration industry, bath room, automobile, escalator, and other places with special need for safety and dramatic temperature changes, and can be used as insulating glass and laminated glass original pieces.

Cons:

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

2, although the strength of tempered glass is stronger than ordinary glass, tempered glass has the possibility of self-explosion (self-rupture) when the temperature difference is large, and ordinary glass does not have the possibility of self-explosion.

Thirdly,What are the precautions for the use of tempered glass?

1, pay attention to protect the corners of the tempered glass

If there is damage at the corners of the tempered glass, the risk of glass self-explosion is multiplied. Because the stress points of tempered glass are all concentrated in the corners, the protection of the corners is particularly important, and the use of tempered glass with damaged corners cannot be treated with caution;

2, to avoid the tempered glass in a long-term state of pressure

In order to the interior beauty, many families will choose to use tempered glass as a table table, generally tempered glass to withstand the pressure between 70mpa to 100mpa, the pressure multiplied by the force area of the glass is the greater pressure it can withstand. Convert to the quality of the item =(pressure * area)/10, if not necessary, do not place heavy objects on the tempered glass desktop for a long time to avoid the pressure value reaching a critical point resulting in the tempered glass breaking;

3, avoid uneven hot and cold

If in an extreme state, the two ends of a piece of glass are subjected to high temperature and low temperature, then 90% of the glass will explode, for example, in the light of the incandescent lamp poured cold water, the glass of the incandescent lamp will break. Although for tempered glass, this situation will be very small, but not afraid of ten thousand is afraid of one;

4. Stay away from acid and alkali

Avoid making tempered glass contact with alkaline substances such as sodium hydroxide (NaOH caustic soda) and hydrofluoric acid (HF), glass is essentially silicon dioxide (SiO2), which will chemically react with the above substances;

5, do not use sharp, hard objects to knock the corners of the glass
