With the rapid development of cities, there are viaducts in many big cities, and the noise nuisance problem brought by them is a problem that almost all big cities will encounter. The development of urbanization will inevitably make people's living environment worse. Villa-style garden-style residence is definitely a luxurious dream for ordinary people. Nowadays, the city has an inch of land and money. In order to solve the problem of traffic congestion, viaduct is obviously one of the best solutions. However, it is almost impossible to keep the viaduct away from the building. You can either live in the suburbs or in the countryside, so you can enjoy the sunshine and good living environment, but you can also lose convenience while staying away from the noisy city. Or you can choose the convenience of the city, but you have to bear the troubles caused by pollution and noise.
Therefore, how to solve noise disturbance has become a hot topic. Although adopting soundproof window method is a passive method to solve traffic noise, the effect is obvious. Soundproof door tell you that practice has proved that the soundproof window installed in areas with serious road noise, indoor noise can be reduced to below 40db of the National zero standard.
Selection of window frames. Soundproof window generally choose plastic steel profiles, multi-cavity plastic steel profiles, and the wall is thicker than aluminum alloy. The sound is not easy to penetrate through the profile. The choice of sound deadening strip. Generally, most of the selected materials are aluminum window frame with rubber sound deadening strip or wool sound deadening strip, but wool sound deadening strip is easy to remove hair after being used for a long time, and rubber becomes hard and aging after being used for a long time. Therefore, sound deadening strip should not only prevent aging but also maintain toughness.
Vacuum glass is a kind of using the principle of flat-shaped thermos bottle, the interlayer of two layers of glass developed and manufactured is vacuum with air pressure lower than 10-1PA, and the inner wall is coated with low radiation film, which is transparent or transparent, A square array of "supports" is set between the two layers of glass to withstand the atmospheric pressure of about 10 tons per square meter, so as to keep the interval between the glass and balance the flat heat preservation space under pressure, new glass deep processing products forming vacuum layer. Vacuum glass "vacuum layer" must be in the "support" square array spacing according to the thickness of the glass plate and mechanical parameters design, between 20mm-40mm. In order to reduce the heat transfer formed by the support "thermal bridge" and make it difficult for human eyes to distinguish, the diameter of the support is very small, and the diameter of the support in current products is 0.3 mm-0.5mm, the height is 0.1 mm-0. Between 2mm. Double-layer laminated glass is a film material sandwiched between two layers of glass, and this film is the same as the support of vacuum glass. The support of vacuum glass is very small, so it can be ignored, the film of laminated glass is as big as the glass, that is, it is all supporting points, and the noise will definitely be transmitted through the support. Of course, if there is a good window profile, make a good window seam seal, double-layer laminated glass can also achieve part of the sound insulation effect. In fact, laminated glass is mainly designed for safety. Some stations and public places use laminated glass. Generally, people often think that the sound insulation performance of double glazing unit is very good, which is actually a misunderstanding. The commonly used double glazing unit consists of two pieces of 3~6mm. The small hollow distance makes the air layer between the two glasses show strong "rigidity" and does not play the role of air spring, the advantages of the general double-layer plate structure are lost. At the same time, due to the resonance of the double-layer structure, the small hollow distance causes the resonance phenomenon to occur at medium and low frequencies, resulting in a decrease in sound insulation. In addition, At present, double glazing unit on the market uses aluminum strip or glass strips to stick two pieces of glass together in production. The Sound Bridge function of aluminum strip and glass strips also makes the sound insulation performance worse. Therefore, the sound insulation performance of double glazing unit structure is not much better than that of single-layer glass. Of course, it is undeniable that the thermal insulation performance of double glazing unit is relatively good.
