Laminated glass is made by sandwiching a strong and thermoplastic resin intermediate film (PVB) between two pieces of glass under high temperature and pressure. The characteristics are as follows: Safety: The elastic intermediate film in laminated glass has the function of absorbing impact and preventing the penetration of impact objects. If the glass breaks, the fragments will firmly adhere to the intermediate film and will not fall off or scatter, thus minimizing the damage. Protective properties: Compared with other glass products, laminated glass has a greater protective effect on people and property. Multilayer laminated glass can withstand bullets, bombs, and violent attacks. Soundproofing: Due to the ability of the interlayer film of laminated glass to reduce the sound and vibration that penetrates the glass, it has a good effect on suppressing noise propagation. Control the characteristics of sunlight: Laminated glass can not only reduce the dazzling visible light of the sun, but also reduce the energy of sunlight penetrating through it, thereby reducing the cooling load and achieving energy-saving effects. Pressure resistance: Laminated glass not only has a certain strength, but also has good water resistance when sealed with compatible glass sealant around it. When the glass is damaged, the connecting effect of the intermediate film prevents the glass from immediately penetrating, so laminated glass can be widely used as underwater glass, such as aquariums, swimming pools, etc. UV blocking performance: The interlayer film of laminated glass has a strong UV filtering function, which helps protect valuable furniture, display items, or store goods from UV radiation and fading, causing the items to depreciate. Typhoon and earthquake resistance: Laminated glass has good resistance to typhoon and gust impacts when exposed to natural environments; And earthquake resistance can prevent glass fragments from falling.
