Laminated glass is a relatively cheap type of safety glass commonly used in construction.
Its safety mainly relies on the film between two pieces of glass.
After the glass is broken, the fragments stick to the film and will not fall off. It is more secure than tempered glass. safe type. Due to the obvious advantages of laminated glass, manufacturers have developed laminated glass with different functions according to actual needs.
Classification of laminated glass:
1. According to the different melting points of the intermediate film, it can be divided into low-temperature laminated glass, high-temperature laminated glass, and insulating glass; the intermediate film can use PVB, SGP, EVA, PU, etc., as well as colored laminated glass and SGX printed intermediate film Laminated glass, XIR LOW-E interlayer laminated glass, etc.
2. According to the different materials of the middle clip, it can be divided into: clip silk, clip painting, clip paper, clip cloth, clip plant, clip silk, etc. Laminated glass with higher added value is embedded with decorative parts (metal mesh, metal plate, etc.), embedded with PET materials, etc., which belongs to laminated glass with both decoration and function.
3. According to the different bonding methods of the interlayer, it can be divided into mixed laminated glass, dry laminated glass and hollow laminated glass.
4. According to the different layers of laminated glass, it can be divided into ordinary laminated glass and bulletproof glass.
Laminated glass is widely used in buildings, what functional requirements should it meet?
A. On the basis of ordinary glass, it should have the ability of anti-seismic, anti-theft, bullet-proof and anti-theft.
B. The internal interlayer film can isolate 99% of ultraviolet rays, and has a protective effect on the color of indoor furniture decoration.
C. Requirements for energy saving coefficient. The interlayer film can reduce the solar radiant heat from entering the room, and at the same time prevent the loss of indoor heat, which can save electricity consumption.
D. Sound insulation. The film layer can buffer the sound waves generated by the sound vibration, thereby achieving the sound insulation effect.
E. High safety factor. The interlayer film has strong adhesion to glass shards and is not easy to penetrate after being impacted.
F. The decorative effect is good, and a variety of colors are available to meet the requirements of the surrounding environment and architectural design.
