Laminated glass is a composite glass product that is made by sandwiching one or more layers of organic polymer intermediate film between two or more pieces of glass. After special high-temperature pre-pressing (or vacuuming) and high-temperature and high-pressure process treatment, the glass and the intermediate film are permanently bonded together. Its performance and characteristics are as follows:
1. High safety: When impacted, the glass may break, but the intermediate film will stick to the fragments so that they will not splash and hurt people, which can effectively reduce the risk of injury to the human body.
2. Strong penetration resistance: The intermediate film has a certain toughness and strength, which can enhance the penetration resistance of the glass. It has a good resistance to external impacts such as bullets and stones, and can be used in some places with high safety protection requirements.
3. Good sound insulation effect: Laminated glass can effectively block the propagation of sound, especially the blocking effect of medium and low frequency sound is more obvious, which can create a quiet indoor environment.
4. High UV blocking rate: The intermediate film can absorb most of the ultraviolet rays, which can effectively prevent indoor furniture, curtains and other items from fading and aging due to ultraviolet rays, and can also reduce the damage of ultraviolet rays to the human body.
5. Good earthquake resistance: When natural disasters such as earthquakes occur, laminated glass can maintain its integrity and is not easy to break and fall, which buys time for evacuation and rescue.
6. Good aesthetics: Laminated glass can use interlayers of different colors and transparencies, and can also be made into various patterns and effects through special processes to meet the aesthetic needs of different buildings.
