Can tempered glass be punched, and how to punch tempered glass

No holes can be opened.

Only before tempering, the holes are machined and then tempered. If you want to open the hole, you need to open it before the glass is tempered, and then tempered. Temperedglass reinforcedglass belongs to safety glass.

Tempered glass is actually a kind of prestressed glass, in order to improve the strength of the glass, chemical or physical methods are usually used; Compressive stress is formed on the surface of the glass, and the surface stress is first offset when the glass is subjected to external force, so as to improve the bearing capacity and enhance the wind pressure resistance, cold and heat resistance, impact and so on. Note the difference with FRP.

Tempered glass can no longer be punched.

This is because during the manufacturing process, the glass is cooled rapidly, and the structural stresses should be in a state of equilibrium. If it is punched, it destroys this state and it will break into small grains. However, it can be annealed and then tempered.

And tempered glass cannot be reused and cut, because it is customized. If it is really tempered glass, once the surface is damaged, it will burst.

Tempered glass is first punched and then tempered, tempered can not be punched after tempering, tempered glass is made of ordinary glass, the strength of ordinary glass is greatly improved, and the deformation ability is reduced, so the destruction is all broken.

Tempered glass, also known as tempered glass, is the use of heating to a certain temperature after rapid cooling method or chemical method for special tempering treatment of glass, its strength is several times greater than that of untempered glass, with good impact resistance, bending resistance and resistance to sudden cooling and sudden heat.

The use of tempered glass and precautions:

The use is more extensive, it is more common in modern decoration, especially in the balcony, bathroom, etc. is often used, because it has safety, so people use more, tempered glass is broken, it will crack into small pieces of round and blunt, which does not hurt people, and belongs to a very safe glass.

To be clear, of course, it can be perforated, otherwise many frameless windows are directly perforated and installed in the tempered glass.

Tempered glass cannot be perforated. Because the compressive stress of the glass surface is adjusted in the production process of the tempered glass, once the tempered glass is punched, the tempered glass will be broken into honeycomb obtuse particles because the balance of uniform compressive stress is destroyed, and it will no longer be used, so it is not possible to punch holes for tempered glass.

Tempered Glass Introduction:Temperedglass reinforcedglass belongs to safety glass. Tempered glass is actually a kind of prestressed glass, in order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass, and the glass first counteracts the surface stress when it bears external force, thereby improving the bearing capacity and enhancing the wind pressure resistance, cold and heat resistance, impact and so on.

Note the difference with FRP.

Glass drill bits for tempered glass drilling。With a glass drill bit, you only need to use a glass drill bit to punch holes in the glass, and it is true that you need to drill while watering, but you don't need to pour too much water. As long as the drill bit does not smoke, take a mineral water bottle, prick a hole in the lid, and hit it with an electric drill.

Robust method, remove and perforate, at present many window glass is tempered glass insulating glass, so first of all, it is necessary to determine the raw material of glass, if it is tempered glass, it can no longer be punched.

Advantages of tempered glassThe strength is several times higher than that of ordinary glass, the flexural strength is 3-5 times that of ordinary glass, and the impact strength is 5-10 times that of ordinary glass, which improves the strength and safety at the same time. It is safe to use, its bearing capacity is increased, and the fragile properties are improved, and even if the tempered glass is damaged, it is a small fragment without acute angles, and the damage to the human body is greatly reduced. The quenching and heating resistance of tempered glass is 2-3 times higher than that of ordinary glass, and it can generally withstand temperature changes of more than 150lc, which has obvious effects on preventing thermal explosion.

Summary. Tempered glass can also be punched, but if you want to punch holes, you need to meet the corresponding conditions, not all tempered glass can be punched as soon as it comes up, first of all, tempered glass can not be too thin, if it is too thin, it is easy to break when punched.

Tempered glass can also be punched, but if you want to punch holes, you need to meet the conditions of the corresponding hall, not all the tempered glass can be punched as soon as you come up, first of all, the tempered glass can not be too thin, if it is too thin, it is easy to break when punched. Limb World.

But I still don't recommend punching.

The tempered glass that we want to open is 10 mm.

OK. It's about 40 centimeters.

Forty centimeters is also OK, provided that the tempered glass can withstand internal and external pressure.

It should be bearable.

After all, it's dangerous to not be able to bear it.

How much does it cost to make such a hole?

Under normal circumstances, it is 15-30 yuan for an ordinary glass hole, which is slightly different in different cities.

How much is Chengdu City?

50-70 yuan.

Is there a professional hole opening master**.

This is not Sorry.

No.

Tempered glass cannot be perforated, tempered glass belongs to safety glass, and there is compressive stress on its surface. When the tempered glass is subjected to external force, for example, we use an electric drill to punch holes in the glass, and the tempered glass will break into small particles. If we want to punch holes in the tempered glass, we can inform the merchant of the glass opening size when customizing the glass, and the manufacturer will strengthen the glass after the ordinary glass is opened.

Tempered glass belongs to safety glass. Tempered glass is actually a kind of prestressed glass, in order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass, and the glass first counteracts the surface stress when it bears external force, thereby improving the bearing capacity and enhancing the wind pressure resistance, cold and heat resistance, impact and so on. So the punching should be carried out before the tempering process.

Choose a tempered glass method

When we choose tempered violence, we must first check whether the glass has 3C certification. Tempered glass belongs to 3C compulsory certification products, and tempered glass cannot be sold without 3C certification. When purchasing, we can use our fingers to wipe the 3C certification, if the 3C logo can be erased, then the certification is fake.

Or we can check the authenticity of 3C certification on the 3C certification network. Shed faction.

When buying tempered glass, everyone should check the appearance of the product. For example, we can use glasses to observe the edge of tempered glass, and you can see that there are colored stripes on the edge of the steel simple key glass, if not, the glass is not tempered glass. When purchasing, we also need to check whether the edges of the tempered glass are flat and smooth.

Carefully observe whether there are bubbles, scratches and other defects on the surface of the glass.

When purchasing tempered glass, you can measure the size and thickness of the glass and check whether the size of the glass meets the requirements. There are many brands of Chain He tempered glass, and we try to choose products from well-known manufacturers. When purchasing, we also need to check whether the packaging of the product is damaged, whether the product has a certificate and so on.

Hello dear, I'm glad for your question, can tempered glass be punched: can the hole be opened, first wash the glass parts to be processed, cool dry or dry, and then mark the punching site; Use a steel file or grinding wheel to burr the perforated or parts that need to be processed, and drip concentrated hydrofluoric acid (. Every 1 hour or so, wipe off the residual liquid with a dry cloth and replace it with a new drop; And so on and so forth.

Usually it takes about 1 day to perforate the glass with a thickness of 1 mm, and it can be corroded quickly if it is less than 1 mm, and it takes about 3 days to penetrate the glass plate with a thickness of 2-3 mm. The rules to be followed for drilling tempered glass: 1 Only tempered glass with a width greater than 8 times the thickness can be drilled.

2. For tempered glass with a thickness of no more than 12mm, the interval from the hole edge to the glass margin should not be less than 1 5 times of the glass thickness; For tempered glass with a thickness of more than 12mm, the interval from the hole edge to the glass edge should not be less than 2 times the thickness of the glass; 3. The diameter of the round hole on the tempered glass should be 1 6mm less than the thickness of the glass; The diameter of the round hole should be less than 1 3 of the width;The radius of the rounding of the corner position of the special-shaped hole in the glass plate should be greater than the thickness of the glass. 4. When the corner position is not less than 90o, the interval from the hole edge to the corner tip should be greater than 6 5 times the thickness of the glass. 5. The concave part should be selected with a fillet radius not less than the thickness of the glass.

Hope mine helps! If you are not clear, you don't have to end the consultation, you can continue to ask it, if you feel satisfied, you can help give a thumbs up!
