For tempered glass, there may be some of the following issues that users may encounter during installation or use. Let's find out:
1. Self-exploding glass
The problem of self-exploding tempered glass and the solution have been posted by Hai Long Glass in previous articles, you can refer to the link below:

2. Optical distortion
Tempered glass is produced on a horizontal tempering line. When the hot glass comes into contact with the roller during tempering, it can cause surface deformation due to a decrease in surface flatness, a phenomenon also known as “roller wave”. Roller waves are often noticed when light reflects off the glass. With glass panels with a thickness of 8mm or more, small scratches may appear on the surface.
3. Anisotropy
Anisotropy, also known as iridescence, appears on the surface of tempered glass
This phenomenon is formed during the tempering process, creating areas of different pressure in the cross-section of the glass. This pressure zone creates double refraction in the glass which is visible in polarized light. Polarized light occurs even in normal daylight conditions. The amount of polarized light depends on the weather and the angle of the sun. The double refraction effect is most noticeable at an angle or through a polarizer. Under the conditions of polarized light, pressure areas on the surface of tempered glass will appear colored spots, sometimes also called "Jaguar".
4. Laminated safety glass cracks on its own
The edge of the glass panel in direct contact with the structural frame or locations with positioning screws will reduce the edge strength of the glass and cause cracking when affected by temperature. Temperatures from different environments of the room such as air conditioners or heaters, when in contact with the glass, will change the temperature and create a temperature difference between the hot and cold environmental zones. In addition, there are other external factors such as the shade of the door frame, places where heat-insulating film is applied to the glass or decorative objects that will cause thermal shock to the glass. And when the pulling force at the edge of the glass is too great, cracking will occur.
5. The glass is stained with mold like an oil spill
Before installing the glass panels placed close together, water wets the glass or the weather has high humidity, creating the phenomenon of vapor absorption on the surface. This vapor does not evaporate quickly, the water molecules will interact and cause The silicate base in the glass is pushed out, and the glass surface will no longer be as smooth as before but will become rough, creating conditions for mold to grow.
Therefore, if the glass has been received at the construction site but has not been installed immediately, it must be stored in a dry place. If in case of water exposure, each glass panel must be separated and used to dry the glass panel thoroughly with paper to avoid mold. develop.
