Tempered glass is a common type of glass in daily life. It is generally used in products such as windows, mobile phone films, furniture and so on. Regarding the tempered glass on the windows, many people have questions. Is the tempered window glass anti-theft? Generally, they will consider the issue of home safety. Let me take a look at the article with the editor below. By the way, is tempered window glass anti-theft? By the way, whether household ordinary glass is tempered or not, and how to distinguish whether the glass of the window is tempered or not.
1. Is the tempered window glass anti-theft?
Is tempered window glass anti-theft? The answer is yes.
Tempered glass has strong safety performance. When the glass is damaged by external force, the fragments will become honeycomb-like obtuse-angled small particles, which are not easy to cause serious harm to the human body. Moreover, the impact strength of tempered glass of the same thickness is 3-5 times that of ordinary glass, and the bending strength is 3-5 times that of ordinary glass.
The quenching and heating resistance of toughened glass is 3-5 times higher than that of ordinary glass, and it can usually withstand temperature changes of more than 250 degrees, which has a significant effect on preventing thermal cracking. Tempered glass is a kind of safety glass, and it is also a qualified material for high-rise buildings.
Second, ordinary household glass or tempered glass
Tempered glass is also known as safety glass. According to current industry standards, high-rise and small high-rise buildings must use safety glass, that is, toughened glass. Tempered glass must be used for all glass below 500 meters above the ground, and tempered glass must be used for a single piece of glass with an area greater than 1.5 square meters, and tempered glass must also be used for inner sashes with windows above 7 floors. Moreover, the door must also use toughened glass.
Under normal circumstances, ordinary glass is easy to be broken and scratched, while the fragments of tempered glass will become honeycomb-shaped small obtuse-angle particles, which are not easy to cause harm to the human body. Compared with the two, it is safer to use toughened glass.
Tempered glass is a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are generally used to form compressive stress on the surface of the glass. When the glass is subjected to external forces, it will first offset the surface stress, improve the bearing capacity, and enhance the glass's own wind resistance. Stress, cold and heat, shock, etc.
Flat tempered and bent tempered glass belong to safety glass. It is often used for high-rise building doors and windows, glass curtain walls, indoor partition glass, daylighting ceilings, sightseeing elevator passages, furniture, glass guardrails, etc.
Three, how to distinguish whether the glass of the window is toughened
There are many ways to judge whether the glass material of a window is tempered glass. The following are the most common ways for reference.
1. Distinguish from the state of fragments formed by the fragmentation of a piece of glass
Generally, the relatively regular small fragments are ordinary tempered glass; most of them are regular small fragments, and a small part of the central area is relatively large fragments, which are regional tempered glass; otherwise, it is not tempered glass. .
2. Listen to the sound
You can use something to knock on the glass. Generally, the sound of tempered glass is clear and crisp; while the sound of ordinary glass is dull.
3. Judging from the refraction of light by glass
If it is tempered glass, you may see rows of circular or oval or long strip patterns with regular blue-gray, dark colors in the middle, and light and fuzzy borders on the glass surface.
4. Use a glass cutter to slide
If it is tempered glass, it is difficult for the glass knife to leave scratches on it.
