What is laminated glass?
Laminated glass is a type of safety glass that consists of two or more layers of glass with PVB (polyvinyl butyrate) coating layers created during a combined process of pressure and temperature. Talaq PVB with different thicknesses, the most practical of which are 0.38 mm, 0.76 mm and 1.52 mm, is used to make all kinds of laminated glass. The number of laminated glass layers is determined based on their type of application. The presence of PVB talc between two layers of glass makes the glass not fall after breaking and the crushed glass particles are kept sticky to the talc and are prevented from being separated and spread in the environment, that is why the use of laminated glass In high-rise buildings, it is very effective in preventing risks caused by natural disasters such as earthquakes and fires, which cause the collapse of normal and tempered glass.
Comparison of laminated glass with normal glass
In the lamination process, polymer layers are placed between two or more layers of glass and the whole assembly is permanently integrated under pressure and heat. The most important characteristic of laminated glass is its fracture pattern. Glass breaks on impact, but the broken pieces stick to the middle layer and the glass maintains its integrity. Laminate glass has a higher safety factor than normal glass. Normal glass shatters into large and sharp pieces in the impact, which can lead to life and death losses. Financially, it becomes huge. Tempered glass is in a better condition compared to ordinary glass. As a result of failure, these glasses are broken into small and unbreakable pieces, which do not pose any danger to life, but the glass collapses anyway. The philosophy behind the emergence of laminated glass was to solve this problem of glass.
Applications of laminated glass
Because of its high resistance, laminated glass is also considered a type of security glass, and in addition to its use in residential buildings (which are used as a kind of sound insulation and material for the visibility of the outside of the building;) in other places, including It is used in airports, office and commercial places, chain stores, showcases of exchanges and gold shops and other places and also as a decorative floor in buildings. Unbreakable glass is also used as car glass because it Due to the elasticity of the glass, the amount of damage caused by breaking it during an accident is reduced and it provides the safety of the driver. In addition, this type of glass is used as bulletproof glass and soundproof glass in security places.
