Laminated glass is a kind of toughened glass for civil use. It can withstand external impact of certain energy change of temperature difference without breaking. Even if it is broken, the whole glass is broken into small particles with obtuse angle similar to honeycomb shape, which is easy to hurt people, so it has certain safety. Toughened glass can't be cut. It needs to cut the size before toughening, has the characteristic of "self explosion". According to different uses, toughened glass can be divided into full toughened glass, semi toughened glass, regional toughened glass, flat toughened glass, bent toughened glass other types.
Laminated glass, as a kind of safety glass, will hurt people with sharp pieces after being broken like ordinary glass due to the adhesion of PVB film between two pieces of ordinary glass. At the same time, the sound insulation sunlight control properties of its PVB intermediate film make it a new building material with energy-saving environmental protection functions: the use of laminated glass can only insulate the 1000 hz-2000 Hz anastomotic noise that can penetrate the ordinary glass, but also block more than 99% of the ultraviolet absorb the heat in the infrared spectrum. As a new type of building materials, laminated glass will play an important role in the use of safety glass.
