What is explosion proof glass, sign, what is fireproof glass logo?

Explosion-proof glass is a glass in which tempered glass is attached to other objects so that the residue will not easily scatter when broken. Generally, there are laminated glass and film glass, all of which belong to explosion-proof glass. Some of the car windshields are added with explosion-proof film, and some are not, but the essence is tempered glass.

Explosion-proof glass is actually ordinary glass after high temperature treatment, so that its molecular structure changes, so that in case of its bursting, its fragments are small round particles, there are no sharp fragments. The technical term is tempered glass. In this way, even if it shatters, it will not cause harm to the human body.

Now the general shower room on the market is known as tempered glass, the subtle difference is in the degree of tempering, good glass is completely tempered, almost less than 100% tempered, more than 8mm glass on the market basically can not reach 100% tempered, so it is not that this tempered glass will never break, but its probability of breaking is very low, even if the broken fragments are rounded, it is not easy to cause harm to the human body.

So there are now two explosion-proof remedies on the market (in addition to the glass itself).One is the film, this practice is like a broken bone clip on the splint, the bone can not be scattered, but the break will still break, so he belongs to a kind of after-the-fact remedy, but also lack of confidence in his own glass, because a good tempered glass will not cause harm to the human body even if broken, so there is no need for film to protect, in fact, it also increases the cost (the outer film is generally more than 200 a square).

Another way is to apply a protective layer on the inner wall of the glass, so that it can effectively prevent the corrosion of the glass by the minerals in the water, so that the structure of the glass is stable so that it will not burst, so this method should be called precaution. The service life of this glass is at least 5 to 10 years longer than that of ordinary glass (one application).

Fireproof glassThe letter sign above is the three C, which is its most significant sign, if it is Class A, it corresponds to the composite fire type, this product must be mandatory by the stateProduct Certificationto be able to sell in the market, so consumers need to check if there is one when they buy3C certification

If it is Class C, it is a monolithic fireproof type, and this glass does not need to pass the mandatory certification. If it is a single piece of fireproof glass, it is marked DFB. If it is composite, it is marked FFB.

This thickness, nominal 25 mm, has reached the Class A fire rating, and the fire resistance time can reach one and a half hours. So it will be displayed.

The front shows its structural type, the back 25 indicates its nominal thickness, the third item shows that its fire resistance is grade A, and the last one indicates the time.

Introduction of fireproof glass

1. Fireproof glass can play a role in fire prevention, once a fire occurs, this glass is not the same as ordinary glass type, it is not easy to burn, and it can also block the spread of fire, which is a preventive type of material.

2. Its fire level and performance are all certified by professionals, and it needs to be processed through a special process, which belongs to a special glass, and the raw material can choose float glass.

The main differences are that the properties are different, the characteristics are different, and the applications are different, as follows:

First, the nature is different.

1. Explosion-proof ballasts are glass-resistant.

Explosion-proof glass is a kind of glass that can resist violent impact, and it is a special glass made by machine processing using special additives and a sandwich in the middle.

2. Ordinary glass.

Ordinary glass generally refers to ordinary flat glass, also known as window glass.

Second, the characteristics are different.

1. Explosion-proof glass.

Compared with other glasses, it has the properties of shock resistance, anti-theft, bulletproof, explosion-proof, and anti-ultraviolet.

2. Ordinary glass.

It has the properties of light transmission, heat insulation, sound insulation, wear resistance, climate change resistance, and some have the characteristics of heat preservation, heat absorption, radiation protection, etc.

Third, the application is different.

1. Explosion-proof glass.

Due to the high impact strength and safety of use of explosion-proof glass, Yuchun is suitable for the ceiling of buildings.

Shower rooms, floors, partition walls, skylights in industrial plants, shop windows, kindergartens, schools, gymnasiums, private houses, villas, banks, jewelry stores, etc.

2. Ordinary glass.

It is widely used in mosaic building doors, windows, walls, interior decoration, etc.

Fireproof glassThe logo is a CCC mark. That is, 3C certification reunion ming.

It is China's compulsory product certification system.

It is a basic security certification. The logo collapse is mainly composed of two parts, the upper part is the 3C sign in the ellipse, and the lower part is the letter + 6 digit number sign. The logo above is the certification system, while the letter + 6 digits below represent the manufacturer of processed glass.

Summary. Yes, if there is no 3C mark on the glass, then it belongs to ordinary glass, and does not belong to qualified tempered glass. In order to protect the personal safety of consumers, our country has made it mandatory to stipulate that tempered glass must be certified by 3C, and it is required that the tempered glass must be printed with the 3C mark, but there is no such mandatory provision for ordinary glass.

Yes, if there is no 3C mark on the glass, then it is a shield from ordinary glass, and it is not a qualified tempered glass. In order to protect the personal safety of consumers, our country has made it mandatory to stipulate that tempered glass must be certified by 3C, and it is required that Bishiqing must be printed with 3C marks on tempered glass, but there is no such mandatory provision for ordinary glass.

Hope it helps, I wish you a happy life! Please kiss and give a thumbs up <>

There is no special sign on the fireproof glass, but GB > stipulates that the lower right corner of each product should have a product mark, enterprise name or trademark that is easy to erase without pretending to be a scumbag. You can use this to identify whether it is fireproof glass or not.

Hope it helps. If my answer is helpful to you, please also give a thumbs up (comment in the lower left corner), look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress. Finally, I wish you good health and a good mood!

Pro-glass with explosion-proof function, generally choose to screen the "explosion-proof glass" logo in the lower right corner of the glass, indicating that the explosion-proof glass implementation standard explosion-proof glass is measured by the size of the impact resistance, there are 4 joules, there are 7 joules, Guangzhou Xianglu explosion-proof glass has a formal test report, and the coal research institute has a false inspection qualified. Explosion-proof glass, is the glass that can prevent violent impact, it is the use of special additives and the middle layer of the sandwich made of machine-made special glass, even if the glass is broken, it will not fall easily, because the middle material (PVB film) or the other side of the explosion-proof glass has been fully bonded. Therefore, explosion-proof glass can greatly reduce the damage to personnel and valuable objects in the event of a violent impact.
