How to analyze tempered glass?

At present, glass is widely used in inorganic non-metallic materials, which can be used in construction, daily use, art, instrument other fields, with a very rich variety. In addition to the general toughened glass printed glass, there are also optical glass, dimming glass other types with high technical requirements.

Toughened glass is rare. What are the advantages of toughened glass? Let's take a look:

1、 Advantages

1. Safety: the strength is several times higher than the ordinary glass, the bending strength is 3-5 times of the ordinary glass, the impact strength is 5-10 times of the ordinary glass, which improves the strength safety at the same time.

2. High strength: it is safe to use, its bearing capacity increases to improve the fragile property. Even if the toughened glass is damaged, it also presents small pieces without sharp angle, which greatly reduces the harm to human body. The properties of toughened glass are 2-3 times higher than that of ordinary glass. It can bear the temperature difference of more than 150LC, which has obvious effect on preventing thermal cracking.

3. Temperature resistance: the temperature difference of toughened glass can reach about 200 ℃, which can bear the temperature change of different weather.

2、 How to distinguish ordinary glass toughened glass

1. Generally, the deep processing manufacturers of toughened glass have their own toughening marks. Most of the toughening marks are trademarks of their own factories. The easiest way to see whether the glass is toughened is to directly find out whether there is a toughening mark.

2. Observe the edge of the glass. In general, toughened glass has no small incision. Even if it does, it will feel "softer" than ordinary glass when touched by hand. Ordinary glass has many small cuts on its edges, which are sharp.

3. When you see the glass in the sun light (you can't put things behind the glass), there will be a layer of mist after tempering. Common is transparent,

4. Knock the glass with fingers, the sound is clear tempered

5. Broken. After the toughened glass is broken, the fragments will be broken into uniform small particles. After the ordinary glass is broken, it is a knife like sharp angle. This is the main difference between tempered glass ordinary glass, but it is no doubt unrealistic.
