Qun'an SGP laminated glass

Qun'an SGP laminated glass

The ideal laminated glass interlayer film for building curtain walls should meet the following requirements:
1. It has high bonding ability to glass and strong tear strength, which can prevent the glass from scattering when it breaks.
2. It has strong protective ability to prevent the damage of natural forces and manpower. Strong resistance to strong winds, earthquakes, violence, theft, etc.
3. Can withstand the sudden impact of indoor personnel, prevent the glass from scattering or the whole out, to avoid indoor personnel flying out of the fall.
4. There is enough residual bearing capacity, and the whole piece will not fall off when the glass is broken and then deformed.
5. The interlayer film has a large shear modulus, so that the two glasses are bent as much as possible, thereby increasing the bearing capacity and bending rigidity of the glass, reducing the thickness of the glass, and reducing the weight of the glass.
6. Colorless and transparent, able to withstand the effects of ultraviolet light, water vapor and external climate change, long-term use without yellowing discoloration.

Product Details


The PVB interlayer film currently used cannot fully meet the above requirements. However, Dongguan Qun'an Plastic Industry Co., Ltd. recently developed a higher performance SGP film for curtain wall laminated glass, to adapt to super high-rise building curtain wall, large-span lighting roof, super large-sized laminated glass, all-glass structure and other laminated glass. High standard requirements.
The characteristics of the group SGP ionic interlayer film, this laminated film has many excellent properties.
It has high strength and shear modulus and excellent mechanical properties: the shear modulus of SGP is more than 50 times that of PVB, the tear strength is 5 times higher than that of PVB, and the hardness is 100 times that of PVB. After the SGP is glued, the glue layer between the two pieces of glass does not substantially slide when the glass is stressed, and the two pieces of glass work as a single piece of glass of equal thickness. In this way, the bearing capacity is twice the bearing capacity of the PVB laminated glass of equal thickness; at the same time, the SGP laminated glass has a bending deflection of only 1/4 of the PVB laminated glass under the same load and equal thickness. As the bearing capacity increases, the deflection decreases and the glass thickness decreases accordingly. It is possible to reduce the amount of glass by about 40%, which also reduces the weight of the curtain wall. Not only is it beneficial to the main structure design, but also the material saving is energy-saving, because the production of each standard box float glass consumes 16Kg of standard coal and consumes 7.5 degrees of electricity. If tempering, homogenization, etc. are added, the energy consumption will be even more.
