In recent years, with the rapid improvement of modern science and technology, the ancient and traditional glass industry has rejuvenated, and various glass products with unique functions have come out. Want to understandTempered glassWhat is the difference with ordinary glass, and the method of distinguishing between tempered glass and ordinary glass, you will know after reading the article.
Tempered glass is safety glass.It is based on the principle of material toughening.It cools instantly when the glass is heated to a softened state.It is a tempered stress layer inside the glass, which increases the ability of the glass to resist pressure and impact. The size of the corn kernels is basically no damage to the human body. Generally, tempered glass is not very straight and has a little twists and turns. Ordinary glass has a surface that is resistant to pressure and impact. It has a sharp knife shape and a sharp edge, which causes great damage to the human body. The glass is very straight, without twists and turns.
A simple way to distinguish between tempered glass and ordinary glass:
With polarized sunglasses, you can see colored stripes, and you should not see it without steel.
Turn the angle to see if there is any pressure spot on the surface of the glass. You will see irregular deformation of the glass on the entire surface.
Looking at the side, when the glass is tempered, it will soften, and the flatness will deteriorate due to the roller table.When facing the face, the open space in the center is an ellipse.
The flatness of tempered glass is worse than ordinary glass.Simple method: put the two glasses close to each other vertically and investigate the two long sides of the two pieces of glass that are close together.Look at the long sides of the two pieces of glass Is there any obvious gap between them? If there are gaps, do they all have a certain arc shape? If so, they should be tempered. Note that they are face to face, not face to back. This requires physical strength. Otherwise, use two exposures Let's take a look at the X-ray film. When you look at the side 70, you should see a blue wind spot after tempering. The flatness of the glass is also significantly lower than that of the glass before tempering.
Bring a flat mirror in the sun, tempered glass is flower, glass is not.
The tempered mark is printed on the glass by high-temperature ink through screen printing.In the process of glass tempering, the high-temperature ink merges with the surface of the glass. Fluoric acid will also leave more significant traces.) Therefore, the simple and direct way to see whether the glass is tempered is to mark it with a tempered mark.
Able to use sharp objects to describe the edge of the glass (the point is that it will not be seen in the future after installation) .If scratches are prone to occur, it means that the glass is not toughened. This indicates that the glass is now tempered. If you break a piece of tempered glass, the fragments will break into uniform small particles and there will be no sharp corners throughout the glass.
