Glass has the role of space amplification and decorative effect, and glass occupies at least 70% of the doors and Windows, so the quality of glass plays a crucial role in doors and Windows.
Tempered glass has always given a good impression of safety and reassurance. So here's the question! On the safety of tempered glass, what is the cause of the glass self-explosion?
The instability of the original glass
The original glass itself contains impurities nickel sulfide, in the glass manufacturing process, if bubbles and impurities are not completely eliminated, they may rapidly expand under temperature or pressure changes and lead to rupture.
The more impurities and bubbles inside it, the higher the self-detonation rate. The current glass production technology can not completely eliminate the existence of nickel sulfide impurities, so the self-explosion of glass can not be completely avoided, which is also the inherent characteristics of glass.
Thermal stress caused by extreme weather
Thermal stress due to temperature change, also known as thermal burst. When the indoor air conditioning is turned on in summer, the outdoor sunlight is exposed, and the surface temperature of the glass suddenly rises or falls, the thermal stress gap formed inside and outside may lead to cracks and breakage. At the same time, extreme weather such as typhoons and rain may also cause glass to burst.
Unprofessional installation leads to self-explosion
The construction personnel are not professional, did not maintain a safe distance of 5~10mm between the glass and the surrounding aluminum frame, or reluctantly loaded the glass into the small aluminum frame, the glass is directly attached to the edge of the aluminum frame, and the edge is forced to explode.
Regarding the purchasing channels for glass
Buy safe to use. When we buy doors and Windows, we must understand the details and functions of doors and Windows products, and understand the "origin" of doors and Windows glass. Therefore, when choosing doors and Windows, we can correspondingly understand whether the original glass of doors and Windows comes from well-known brands, and whether the glass surface is printed with the 3C mark. Choose brand manufacturers for our doors and Windows safety to add protection!
Regarding the size of glass area
We all know that the safety index of glass is much lower than that of the wall, so the glass of home doors and Windows is not necessary to be too large. The larger the glass area, the greater the pressure of the profile structure, and the greater the chance of elastic movement and shaking of the doors and Windows; And with the increase of the floor-to-ceiling window glass area, the thickness and strength of the single piece of glass should also be improved accordingly, so that the glass has enough wind pressure resistance.
