Properties and applications of laminated glass

Laminated glass consists of two or more pieces of glass, sandwiched between a layer or multiple layers of intermediate film (PVB, SGP, EVA, PU and other materials) through special high temperature process, so that the glass and the intermediate film bonding as a whole, become a product, become the real laminated glass. Now let's learn about laminated glass.

1, safety: when hit by external force, due to the elastic intermediate layer has the effect of absorbing impact, can prevent impact material penetration, even if the glass is damaged, it can only produce fine crack similar to the spider network, the debris firmly adhered to the intermediate layer, can avoid personal injury or property loss caused by falling glass debris. Whether installed vertically or tilted, it can withstand the penetration of external impact, and the whole piece of glass remains intact, can continue to resist impact and wind and rain until replacement.

2, anti-theft (anti-penetration) : PVB laminated glass is very tough, even if the thief will crack the glass, because the middle layer of glass firmly adhered to together, still maintain integrity, so that the thief can not enter the room, has a protective effect on people and property. The standard "two clip one" glass can withstand the penetration of the general external impact, even if there is a strong damage of the opening, the opening is very small. Once damaged, the middle layer can still protect the building until the glass is replaced.

3, sound insulation: glass is a kind of ancient iron material, is not an effective sound barrier, if the noise through the glass conduction, indoor people have an impact; Because of the damping function of PVB film on sound wave, laminated glass can effectively inhibit the propagation of noise.

4, UV protection function: in the window design, natural light conduction plays a very important role, but too much sunlight will lead to too high heat, laminated glass has a variety of stable coloring, PVB film can absorb 99% of the UV, which helps to protect valuable furniture, wall charts, displays or commodities from UV radiation and fade. Most of the absorbed energy is lost by re-radiation and convection.
