Laminated glass consists of two or more pieces of glass, with one or more layers of intermediate films (PVB, SGP, EVA, PU and other materials) sandwiched between them. After special high-temperature processing, the glass and the intermediate film are bonded as a whole, becoming a product and a real laminated glass.
Laminated glass is mostly used for windows in automobile manufacturing, large glass curtain walls or high-rise buildings. On the one hand, compared with ordinary glass, laminated glass has better quality and is resistant to use; On the one hand, when the laminated glass is broken, it will be granular and will not be sharp enough to cause harm to the human body. Let's learn about the laminated glass together.
When impacted by external force, the elastic interlayer can absorb the impact and prevent the penetration of the impact object. Even if the glass is damaged, it can only produce tiny cracks similar to spider webs. Its fragments firmly adhere to the interlayer, which can avoid personal injury or property loss caused by the falling of glass fragments. Whether installed vertically or obliquely, it can withstand the penetration of external impact, and the whole glass remains intact, which can continue to withstand impact and shelter from wind and rain until replacement.
PVB laminated glass is very tough. Even if the thief knocks the glass, the middle layer of glass firmly sticks together to maintain integrity, making it impossible for the thief to enter the room, which has a protective effect on people and property. The standard "two clip and one" glass can withstand the penetration of ordinary foreign impact objects. Even if it is damaged by strong force, the opening is very small. Once damaged, the middle layer can still protect the building until the glass is replaced.
glass is a kind of ancient iron material, not an effective sound insulation barrier. If noise is transmitted through glass, it will have an impact on indoor people; Because PVB film has the function of damping sound waves, laminated glass can effectively ease the propagation of noise.
In window design, natural light transmission plays a very important role, but too much sunlight will lead to too much heat. Laminated glass has various stable colors. PVB film can absorb 99% of the ultraviolet light, which helps protect valuable furniture, wall charts, displays or commodities from fading due to the influence of ultraviolet radiation. Most of the absorbed energy is dissipated outside by re radiation and convection conduction.
