As we all know, toughened glass forms compressive stress on the surface of glass through chemical or physical methods, and its firmness is far superior
For ordinary glass, but in fact, if it is improperly used or lacks maintenance, tempered glass will also have the risk of bursting and breaking. Today, let's talk about how to maintain tempered glass.
1. Focus on protecting the corners of tempered glass
The middle part of the tempered glass partition is relatively firm, and the four corners are relatively weak, so the protection of edges and corners is particularly important. The safety hammer of the sign on the bus window glass is at the corner of the glass, which also makes use of the characteristics of tempered glass.
2. Avoid keeping tempered glass under pressure for a long time
Try not to place heavy objects on the surface of tempered glass for a long time to avoid crushing when the pressure reaches the critical point. The general tempered glass bears a pressure of 70mpa~100mpa, which is multiplied by the glass
The stress area of glass is the maximum pressure it can bear.
3. The tempered glass partition is pasted with an explosion-proof membrane
Some tempered glass needs to be manually pasted with an explosion-proof membrane to prevent the random flying of fragments during glass self-explosion. When selecting an explosion-proof membrane, try to select the explosion-proof membrane that has been certified and qualified for production safety membrane.
4. Ensure uniform heating
Under some extreme conditions, if high temperature and low temperature are applied to both ends of glass, the glass is very easy to self-explode. For example, if you pour cold water on a lighted incandescent lamp, the glass of the incandescent lamp will break. Therefore, the glass must be heated evenly.
5. Keep away from acid and alkali substances
Glass is essentially silicon dioxide (SO2), and the chemical reactions will occur when contacting with sodium hydroxide, hydrofluoric acid and other substances.
6. Pay attention to sharp objects
Although the strength of tempered glass is very high, the pressure on the glass at the contact point of sharp objects is relatively large. Once
Injury and impact, the glass is easy to be slightly cracked due to great external force.
