Laminated glass refers to a transparent adhesive plastic film adhered between two or three layers of glass. It combines the strength and toughness of plastic with the hardness of glass, enhancing the glass's resistance to breakage. After undergoing special high-temperature pre-pressing and high-temperature high-pressure treatment, the glass and the interlayer film are permanently bonded to form a composite glass product.
The characteristics and functions of laminated glass: Even if the glass breaks, the fragments will adhere to the film, and the surface of the broken glass remains clean and smooth. This effectively prevents incidents of fragments puncturing and penetrating and falling, ensuring personal safety.
Except for automobiles, most building glass uses laminated glass. This is not only to avoid injury accidents, but also because laminated glass has excellent seismic intrusion resistance. The intermediate membrane can withstand continuous attacks from weapons such as hammers and firewood knives, and can also resist bullet penetration for a considerable period of time. Its level of security protection can be said to be extremely high. The glass breaks safely. It may shatter under the impact of a heavy ball, but the entire piece of glass still maintains an integral interlayer, and the fragments and sharp small pieces are still stuck to the interlayer film. When this kind of glass breaks, the fragments do not disperse and it is mostly used in vehicles and other means of transportation. Tempered glass requires a considerable impact force to break. Once it breaks, the entire piece of glass shatters into countless fine particles, leaving only a few broken pieces in the frame. Ordinary glass shatters easily upon impact, presenting a typical breaking condition and generating many long, sharp-edged fragments. When wire-reinforced glass breaks, mirror-toothed fragments surround the opening, and there are many glass fragments left around the penetration point. The lengths of the broken metal wires vary.
