Due to the low noise of the workshop itself and the strict inspection of air cooler machine, many enterprises have high requirements on noise . When industrial air cooler are installed to deliver cool air to the workshop, the air ducts are affected by wind speed and pressure. There will be a sound of blowing. If the design is not reasonable, the air duct may make abnormal noise and bring some noise pollution to the environment. If you want to reduce the noise in this situation, you must install sound insulation cotton on the air supply duct

In fact, in the actual use of air duct sound insulation cotton, we usually encounter two types, sound-absorbing cotton and sound-insulating cotton. The sound insulation cotton material does block the transmission of sound, but it is easy to cause sound energy reflection. Good sound-absorbing and sound-insulating cotton materials, for example, our main purpose is sound insulation, so to put it bluntly, it is to “eliminate” the noise. It is a kind of porous material with laminated step density, and the holes inside are connected. After the sound enters, it will rub against the hole wall of the material, transform the energy, and finally achieve the purpose of attenuating the sound energy. When we directly put the sound insulation cotton on the air duct, the sound insulation effect of choosing the corresponding material is very good. If there are two situations where there is no effect or the effect is not obvious: one is that the material used itself has no effect, which is related to the material and structure, then you can replace it with an effective sound-proof cotton material and the effect will come out by itself. Another situation is that the normal installation method of sound insulation cotton should be pasted on the surface of the air duct to ensure that there is no flatness and no hollowing, that is to say, only in this way can the best sound insulation effect be achieved.

Do you know that putting sound proof cotton on the air duct of water air cooler can not only eliminate sound, but also play a certain role in heat preservation. At the same time, when the industrial evaporative air cooler is inspected, the noise and various indicators are more suitable for the requirements, especially quietness is required. environment, the air duct is processed in this way, which is also excellent for office workers, and the sound insulation cotton is more decorative than the hard iron sheet: soft, rich natural material texture experience, a variety of available Selected modern color system, simple decorative shape. Secondly, it has strong impact resistance: soft, natural texture, high elasticity, it will not break under the impact of huge external force, it can withstand unexpected impact, and protect the integrity of the air duct.
