Laminated glass is a composite glass made of a tough polyvinyl butyral film (PVB) sandwiczed between two or more pieces of glass and processed at high temperature and pressure. Because the toughness of the PVB film is very good, when the laminated glass is violently hit and broken by external forces, the film layer will absorb a lot of impact energy, and make it rapidly attenuated, so the laminated glass is difficult to be broken: even if the laminated glass is broken, the glass fragments are basically adhered to the film, keeping the whole laminated glass fragments do not fall off, so it becomes a real sense of safety glass.
Widely used in building lighting roof, awning, overhead ground, high-grade curtain wall doors and Windows, Windows, furniture, elevators and so on.
Peculiarity
1. Safety: the laminated glass installed on the building is affected by any external force, even if the glass is broken, it can still remain intact in the original frame, and still has a certain role in wind and rain protection. Therefore, laminated glass is the true sense of safety glass.
2. Noise reduction :PVB film has an obstructing effect on sound waves, thereby reducing noise and reducing noise interference at work or home.
3. Anti-ultraviolet: It has a great barrier effect on ultraviolet rays in the sun (up to more than 99%) to avoid ultraviolet radiation. Therefore, it can protect indoor valuable home counties or artworks from the influence of ultraviolet light and fade.
4. Bulletproof and explosion-proof: The use of multi-layer laminated glass can produce a variety of levels of bulletproof and explosion-proof glass.
5. Hurricane and earthquake resistance: Due to the high tenacity and strong adhesion of laminated glass, even if the laminated glass is broken, the fragments are still retained in place, which is more suitable for use in hurricane and earthquake areas.
