Explosion proof glass is a kind of glass that can prevent violent impact. It is made by machine with special additives and interlayer in the middleSpecial glass。
Chinese name
Explosion proof glass
Foreign name
explosion-proof glass
Thickness
0.76mm、1.14mm、1.52mm
Usefulness
Reduce the harm to people when encountering violent impact
Interpretation
Glass that can prevent violent impact
Features
High safety, more efficiency, and more energy saving
Even if the glass is broken, it will not fall down easily, because the material in the middle（PVB film）Or the explosion-proof glass on the other side has been fully bonded.Therefore, explosion-proof glass can greatly reduce the injury to personnel and valuables when encountering violent impact.
The color of explosion-proof glass is mainly transparent, which can also be usedTinted glassProduction, such as F Green, Volt Blue, Grey Tea Glass, European Grey, Gold Tea Glass, etc.
The film thickness used for explosion-proof glass is 0.76mm, 1.14mm, 1.52mm, etc. The thicker the film thickness, the better the explosion-proof effect of glass.

Explosion proof glass can be divided into two categories according to different production and processing technologies:
Ordinary explosion-proof glass
Explosion proof glass
Ordinary explosion-proof glass with single glass structureFloat glassMade by intensive treatmentSpecial glassThe strengthened glass surface has a strong resistance to violent impact. As the glass thickness increases, the explosion-proof effect of this type of glass continues to increase. The maximum thickness is generally 20 mm, and the glass with a thickness of more than 20 mm is made of explosion-proof glass. It is difficult to strengthen the treatment at one time. You must be careful when selecting ordinary explosion-proof glass user groups.
Once the ordinary explosion-proof glass is broken, the glass will become fragments and cannot effectively resist the wind pressure or the secondary impact of heavy objects.Strictly speaking, ordinary explosion-proof glass does not belong to "explosion-proof glass" in the true sense.
Reinforced explosion-proof glass
The reinforced explosion-proof glass is made by clamping two or more pieces of float glass with a strong PVB film in the middle, pressing it with a hot press and discharging the middle air as much as possible, and then putting it into a high-pressure steam kettle to dissolve a small amount of residual air into the adhesive film under high temperature and pressure.
The specification of explosion-proof glass in the domestic market is more than 300 mm * 300 mm square, which is smaller than 300 mm * 300 mm. At present, there are very few manufacturers with production capacity in this field. This kind of ultra small explosion-proof glass is widely used in underground rescue cabins in coal mines. Because of the high processing difficulty, the price has always been relatively expensive.
The thickness of reinforced explosion-proof glass mainly includes: 8mm - 10mm, 12mm-14mm, 16mm-18mm, 20mm - 22mm, 24mm-26mm, 30mm-32mm, 38mm-40mm.

High security: Because the PVB in the middle layer is tough and has strong adhesion, it is not easy to penetrate after being damaged by impact, and the fragments will not fall off, and it is tightly bonded with the PVB film.
More effective: Compared with other glasses, it has the properties of shock resistance, anti-theft, bullet proof, explosion-proof, UV protection, etc.
More energy saving: The middle PVB layer can reduce the solar radiation, prevent the loss of energy, save the power consumption of air conditioners, and buffer the sound wave vibration products to achieve sound insulation.But the sound insulation effect is not ideal, because it has no vacuum layer.

Due to the high height of explosion-proof glassImpact strengthTherefore, it is suitable for the ceiling, shower room, floor, partition wall of buildings, skylights of industrial plants, shop windows of shops, kindergartens, schools, gyms, private residences, villas, madhouses, banks, jewelry stores, securities companies, insurance companies, post offices, museums, prisons and other places.
Explosion proof glass is also often used in public facilities such as airports, hotels, office buildings of government agencies, or places prone to accidents (such as French windows, commercial residential buildings).
At the same time, the product is also widely used in military and high-tech industries, such as spacecraft, military instruments, solar cells andSolar receiverIn the industrial field, it is used in composite shock absorption steel plate, mining explosion-proof glass, etc.
Explosion proof glass
Some people in the market willWired glassIt is also included in the category of explosion-proof glass, and the wired glass isOrdinary glassBefore molding, iron wire/steel wire is inserted into the middle part of the glass at one time. The wired glass has not been strengthened and cannot withstand gravity impact. Its glass strength is no different from that of ordinary glass.Therefore, it is not really "explosion-proof glass".
But if two pieces of wired glass are made of PVB filmsandwich glassUnder this premise, it can be called explosion-proof glass, but its explosion-proof effect is inferior to that of explosion-proof glass made of strengthened glass.
In addition, some people also call explosion-proof glassHigh pressure resistant glassThis is mainly from the perspective that both have the common effect of withstanding certain pressure.Before purchasing, it is necessary to check the environmental requirements for the use of glass.
