[China Glass Network] At present, urban noise has become an important part of environmental pollution, which not only interferes with people's normal life and work, but also seriously affects physical and mental health. Noise pollution mainly includes industrial noise, social noise and traffic noise. With the rapid expansion of urban motor vehicle ownership, it has stimulated the rapid development of transportation facilities, and thus has urban expressways, traffic trunk lines, and urban railway construction. These new transportation facilities make it difficult to find a quiet place in the city. Therefore, how to solve the noise nuisance has become a hot spot of attention today.
Today, let's talk about the solution to noise pollution. It is a good strategy to block noise by purchasing soundproof doors and windows (door and window decoration renderings). Let's take a look at the way to buy soundproof windows and doors.
First, the soundproof glass window to buy
In the past, because the city was not developing fast, many windows in the houses did not pay attention to sound insulation. With the rapid development of urbanization, the noise is gradually increasing. Therefore, when doing window decoration, you should try to buy window glass with better sound insulation. window frame.
1. Look at the materials including aluminum profiles, glass, hardware, whether the color is consistent, and whether the hardware assembly is complete.
2, look at processing high-quality aluminum alloy window, fine processing, tangential smooth, consistent angle (the main frame is usually 45 degrees or 90 degrees), in the splicing process should not appear more obvious gaps, smooth switch.
3, look at the glass to see if it is hollow glass, there is no coating, plating composite film is generally resistant to corrosion, wear, high gloss.
4, look at the size to see if the window size is correct.
Second, sound insulation door purchase points
The doors and windows in the room are thinner than the walls, so in addition to the windows, the doorway is another key to blocking noise. The security doors and interior doors on the market have corresponding soundproofing products. What should you pay attention to when purchasing?
Core-filled soundproof door: filled with glass wool or rock wool in the door leaf core, and the door fan is sealed with a sponge rubber strip.
Outer-sounding door: a layer of artificial leather is wrapped on the outside of the ordinary wooden door fan, the artificial leather is filled with rock wool, and the long artificial leather bead is nailed with the foaming nail, and the gap around the gap is sealed with a sponge rubber strip.
Soundproof fireproof door: The sound-absorbing material such as rock wool is embedded in the wood frame of the door leaf. The outer part is inlaid with asbestos board, galvanized iron sheet and refractory fiber board. The gap around the gap is sealed with a sponge rubber strip.
1. The formula for weight sound insulation is directly related to the density of the material. Therefore, the sound insulation with high density is relatively good, and the molded door is relatively light. This is the root cause of poor sound insulation of the molded door. But note: the soundproof cotton in the middle of the flat hollow door will be more soundproof than the solid wood door.
2. Look at the thicker surface layer. The thicker the sound insulation, the better. The general laminate of the wooden door should be 8mm thick. The thickness of the surface layer is also good, but the cost is increased. However: the iron surface of the iron plate fire door is 3mm thick, and the sound insulation effect is also good.
3, look at the flatness of the wooden door, the better the combination of the same door, regardless of the structure. As long as the deformation of the wooden door is not soundproof.
