Is tempered glass equivalent to explosion-proof glass?
The obvious feature of tempered glass is its high strength. Explosion-proof glass is a special glass made by machine processing using special additives and interlayers in the middle. Even if the glass is broken, it will not fall easily because the material in the middle (PVB film) or the explosion-proof glass on the other side has been fully bonded.
Advantages and disadvantages of tempered glass:
1. The strength is several times higher than that of ordinary glass and it is resistant to bending.
2. It is safe to use. Its increased bearing capacity improves its fragile nature. Even if tempered glass is damaged, it will be small fragments without sharp angles, which greatly reduces the harm to the human body. Although tempered glass is stronger than ordinary glass, tempered glass has the possibility of self-explosion (self-breakage), while ordinary glass does not have the possibility of self-explosion.
3. The surface of tempered glass will have unevenness (wind spots) and slight thickness thinning. The reason for thinning is that after the glass softens in hot melt, it is quickly cooled by the strong wind, which makes the crystal gap inside the glass smaller and the pressure greater, so the glass is thinner after tempering than before tempering. Generally, 4~6mm glass becomes 0.2~0.8mm thinner after tempering, and 8~20mm glass becomes 0.9~1.8mm thinner after tempering. The specific degree depends on the equipment, which is also the reason why tempered glass cannot be made into a mirror.
4. Flat glass used in construction after a tempering furnace (physical tempering) generally has deformation, and the degree of deformation is determined by the equipment and technical personnel. To a certain extent, it affects the decoration effect (special needs are excluded).
Explosion-proof glass features:
1. High safety: Because the PVB in the middle layer is tough and has strong adhesion, it is not easy to penetrate after being impacted and broken, and the fragments will not fall, and they are tightly bonded to the PVB film.
2. More functions: Compared with other glasses, it has the functions of shock resistance, anti-theft, bulletproof, explosion-proof, and UV protection.
3. More energy-saving: The central PVB layer can reduce solar radiation, avoid power loss, save air conditioning power, and buffer the sound wave vibration products, thereby achieving a sound insulation effect. However, the sound insulation effect is not ideal because it does not have a vacuum layer.
