What Are the Characteristics of Laminated Glass Interlayer Films?

The ideal laminated glass interlayer film for building curtain wall should meet the following requirements.

1. It has high bonding ability to glass and strong tear resistance, which can prevent glass from flying away when broken.

2. It has strong protection ability, which can prevent the damage of natural force and manpower. Sufficient resistance to strong wind, earthquake, violence, theft, etc.

3. It can withstand the sudden impact of indoor personnel, prevent the glass from flying out or falling out as a whole, and prevent indoor personnel from flying out and falling.

4. There is sufficient residual bearing capacity, and the glass will not fall off in one piece when it is bent and deformed after being broken.

5. The interlayer film has a large shear modulus, so that the two pieces of glass can be bent as much as possible in the entire section, thereby improving the bearing capacity and bending stiffness of the glass, reducing the thickness of the glass, and reducing the weight of the glass.

6. Colorless and transparent, it can withstand the influence of ultraviolet rays, water vapor and external climate changes, and it will not turn yellow and change color after long-term use.

The PVB film currently used cannot fully meet the above requirements. However, E&N film has an interlayer film for curtain wall laminated glass developed in recent years. E&N film is suitable for high-rise building curtain walls, large-span lighting roofs, and large and thick laminated glass , all-glass structure and other high standard requirements for laminated glass.

The features of ionoplast interlayer films

The ionoplast interlayer film has high strength, shear modulus, and mechanical properties. The shear modulus is more than 50 times that of ordinary PVB, and the tear strength is 5 times higher than that of ordinary PVB. After lamination of Ien films, the adhesive layer between the two pieces of glass will basically not slip 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 load-bearing capacity is twice that of ordinary PVB laminated glass with equal thickness; at the same time, under the condition of equal load and equal thickness, the bending deflection of Ion ionic interlayer laminated glass is only a quarter of that of ordinary PVB laminated glass. Due to the increased bearing capacity and reduced deflection, the thickness of the glass will decrease 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 design of the main structure, but also saves material and energy.
