Product characteristics of PVB laminated glass:
1) Safety precautions: When the glass is broken by impact, the impact resistance of various types of glass is obviously different. Because PVB film has the effect of absorbing impact energy and strong bonding force, the glass fragments are still firmly bonded to the PVB film, and the impact object is not easy to penetrate the glass, thereby reducing the damage to the human body and preventing natural disasters and man-made damage , Prevent all kinds of accidents from happening.
2) Thermal insulation performance: Laminated safety glass has good thermal insulation performance, which can reduce the heat exchange between the heating in the room in winter and the cold air in the room in summer with the external environment, so as to achieve the effect of energy saving.
3) Sound insulation performance: when the sound wavelength in the air is equal to the bending wavelength of the sound in the glass, the coincidence effect will occur. In some frequency ranges, ordinary glass has a strong sound transmittance. Since sound is a combination of sound energy at different frequencies, effective sound control must require a wide range of sound levels to be reduced. As the PVB film produces vibration damping when sound waves pass through the glass, it can effectively block the consistent noise of 1000-2000 Hz that is often encountered with ordinary glass.
4) Infrared isolation performance: The PVB film in the laminated safety glass can filter 99.8% of the ultraviolet rays in the sun, which is the biggest advantage of the laminated safety glass over other glasses. Ultraviolet rays in sunlight have sterilization and medical effects, and are also the cause of the fading of fiber products, coatings, furniture, and daily utensils. Laminated safety glass using PVB film can isolate this ultraviolet light and is widely used in art galleries, museums, and high-end merchandise display windows.
