Sound insulation glass is a kind of glass product that plays a certain role in shielding sound, usually double-layer or multi-layer laminated glass. Sound insulation and damping glue (film) in the middle of laminated glass plays a key role in weakening and attenuating sound propagation. Glass products with sound insulation function include laminated glass.
Insulating glass consists of two layers of glass, and the periphery of the glass is sealed by sealing strips and glass strips with high strength and high air tightness composite adhesive. The 6-9mm air layer in the middle is filled with drying gas, and the frame is filled with desiccant to ensure the drying of air between glass sheets. As shown in the figure. Its characteristics, because it has a certain cavity and good thermal insulation effect, are widely used in northern cities.
Sound insulation glass's principle of sound insulation effect: all kinds of outdoor sound sources vibrate to produce noise, and the noise propagates through the air medium. When the noise reaches the doors and windows of sound insulation glass, it is attenuated by sound insulation glass. Especially when the noise passes through the sound insulation and damping glue, the intermediate frequency noise and high frequency noise are absorbed, distorted, damped and attenuated by the sound insulation and damping glue, which can effectively filter out the intermediate frequency noise and high frequency noise, and finally the noise entering the room is only about 5%.
Common, annoying, annoying, insomnia noises "and" and "have basically disappeared, and they are hard to hear. The feeling indoors suddenly became soft, and it was much more comfortable to stay indoors. As the saying goes: living in the downtown area and living in the countryside will come true.
