Among them, PVB laminated glass is the most popular, because laminated glass, as a kind of safety glass, is produced in accordance with national standards. Even if it is cracked by impact, the fragments will still be glued to the film due to the bonding effect of PVB film sandwiched between two ordinary glass pieces, and the whole broken glass surface will remain clean and smooth, without dispersion. The strength of the laminated glass made of tempered glass will be greatly improved, and the fragments will become small particles of obtuse corner similar to honeycomb, which effectively prevents the splinters from stabbing and falling, which is not easy to cause serious injury to the human body and ensure personal safety. It is the first choice for many building installations. In Europe and America, most of the building glass is laminated glass, which is not only to avoid injury accidents, but also because laminated glass has excellent sound insulation and UV protection ability. This is because the PVB glue has a strong barrier effect on the sound wave, the sound wave is significantly weakened when passing through the laminated glass, reducing the noise interference of the work place or family life, to maintain a quiet and comfortable office environment. At the same time, it has a very good anti-ultraviolet effect (anti-ultraviolet rate of more than 90%), which not only protects people's skin health, weakens the transmission of sunlight, reduces the energy consumption of refrigeration, but also prevents indoor valuable furniture, exhibits, artworks and other items from fading due to the influence of ultraviolet light. Laminated glass has many advantages, widely used in architectural grilles, high-altitude platforms, high-grade curtain wall doors and Windows, furniture, window, aquarium and other items and occasions, used in home decoration will also have unexpected good results.
