High temperature causes tempered glass to “self-explosive” frequently

[China Glass Network] After entering the volt, the hot summer days above 35 °C have come one after another, which has caused many citizens to call "hot explosion." In the face of this hot weather, can you believe it? The tempered glass, which has always been known for its solidity, frequently “self-destructs” in high temperature days.

How to prevent bursting, it is more economical to attach tempered glass to the explosion-proof membrane, and it is also possible to install tempered laminated glass to avoid splashing of the glass when the glass bursts. At the same time, before installing and using tempered glass, you must first check whether the “CCC” compulsory product certification mark is printed, and ask professional construction personnel to install it in a standardized manner. The self-explosion of tempered glass has a certain relationship with the weather being too hot. Usually, there is rarely a case of tempered glass self-explosion. There is also a high temperature during the day in the summer, and low air-conditioning temperatures in the evening. The uneven heat and cold glass is also prone to self-explosion.

And the self-explosion of tempered glass is mainly the reason for the installation and the quality of the glass itself. "The coefficient of thermal expansion of tempered glass is relatively high. If there is not enough space for expansion and contraction during the installation process, it will easily lead to self-explosion of the glass in thermal expansion." In addition, the inside of the glass contains stones, bubbles and impurities, which are in the production process. If it is not completely fused, cracks are easily generated, and the glass contains nickel sulfide crystals, and these materials are also prone to burst by thermal expansion.

Compared with ordinary glass, tempered glass has the advantages of high toughness, bending resistance and high safety performance. Nowadays, in our daily life, the application of tempered glass has become more and more frequent. The doors and windows, sun room, sliding door, shower room, coffee table, etc. in the home, as well as the entrance and exit doors, windows and curtain walls of office buildings and buildings, can be seen almost everywhere. Tempered glass.

Professionals reminded that when cleaning and maintenance of tempered glass on weekdays, avoid contact with tempered glass with alkaline substances such as sodium hydroxide (NaOH caustic soda) and hydrofluoric acid (HF), because the main component of the glass itself is silica. (SiO2), the above substances will react once they are combined. Therefore, in the daily cleaning, wipe with a wet towel or newspaper, if the stain can be wiped with a towel, beer or warm vinegar, you can also use the glass cleaner sold on the market, avoid acid and alkaline Strong solution cleaning. The surface of the glass in winter is easy to frost, and it can be wiped with cloth dampened with salt water or white wine, which works well. Once the patterned frosted glass is dirty, it can be removed by rubbing the toothbrush with a cleaning agent along the pattern.
