汽车机械的躁动让很多商家绞尽脑汁停止控制，隔音棉就是其中的一种材料。他的隔音效果有多严重？我们可以停止这个材质设置吗？
The restlessness of automobile machinery makes many businesses rack their brains to stop control, and sound insulation cotton is one of them. How serious is his sound insulation effect? Can we stop this material setting?
其来源也是由于汽车噪音的产生。使用主要是汽车的底盘、车门、引擎盖、车窗、车顶等容易产生噪音的零部件。贴在引擎盖上还可以避免雾天行车带来的视觉冲击。
Its source is also due to car noise. The use center is mainly the chassis, door, hood, window, roof and other parts that are prone to noise. Sticking it on the hood can also avoid the visual impact of driving in fog.
原理：机械刺激声→声波被输送到空气中→棉花原料的多纤维结构→声波通过许多纤维的反射穿过棉花的过程，相互叠加，相互碰撞，而声波能量转化为热能→此时降低声波强度→使声音消失。
Principle: mechanical stimulation sound → sound waves are transmitted to the air → multi fiber structure of cotton raw materials → the process of sound waves passing through cotton through the reflection of many fibers, superimposing and colliding with each other, and the sound energy is converted into heat energy → at this time, the sound intensity is reduced → the sound disappears.
作用：使机械声不再响亮，剩下的只是机体的振动；减少并有效缓解底盘金属疲劳，延长车身使用寿命；防水性能好，防止钣金腐蚀；有效降低和吸收机体金属零件的振动能量，减缓零件的磨损，延长零件的使用寿命；保持引擎盖表面的油漆；保温等效果。
Function: make the mechanical sound no longer loud, and the rest is the vibration of the body; Reduce and effectively alleviate chassis metal fatigue and prolong the service life of the car body; Good waterproof performance, preventing sheet metal corrosion; Effectively reduce and absorb the vibration energy of metal parts of the body, slow down the wear of parts, and prolong the service life of parts; Maintain the paint on the hood surface; Heat preservation and other effects.
步：在
济南宝马汽车专修发动机舱盖上套上相应的防火隔音棉，因为隔音棉可以提供发动机产生的噪音，而且还具有隔热的作用。长期高温会损坏车罩外部的油漆，隔音棉也会起到保护油漆的作用。
Step 1: put the corresponding fireproof and sound insulation cotton on the engine compartment cover of BMW in Jinan, because the sound insulation cotton can not only provide the noise generated by the engine, but also has the function of heat insulation. Long term high temperature will damage the paint on the outside of the car cover, and the sound insulation cotton will also protect the paint.
第二步：此时可以在车厢内的底盘和后车厢的底盘上安装减震吸音垫、防水隔音棉和减震垫，这也是为了减少由振动形成的共振引起的声音。还可以降低轮胎在运动中引起的路面噪音，降低排气引起的噪音。
Step 2: at this time, shock absorption pads, waterproof and sound insulation cotton and shock absorption pads can be installed on the central chassis and the chassis of the rear compartment, which is also to reduce the sound caused by resonance formed by vibration. It can also reduce the road noise caused by tires in motion and the noise caused by exhaust.
第三步：可以在门的装饰板上贴上防震垫和隔音棉，发生触感会导致内板部件掉落。这时，隔音棉就具有降低共识和保持饰边稳定性的作用。
Step 3: you can stick shockproof pads and sound insulation cotton on the decorative panel of the door, and the touch will cause the inner panel components to fall. At this time, the sound insulation cotton has the function of reducing consensus and maintaining the stability of trim.
第四步：前后轮的挡泥板也需要贴隔音棉，因为这两个也是行驶时振动带的传递区域。它还可以减少由道路和金属结果引起的摩擦引起的噪音，也可以减少其驾驶员受到噪音的影响。
Step 4: the mudguards of the front and rear wheels also need to be pasted with sound insulation cotton, because these two centers are also the transmission areas of the vibration belt when driving. It can also reduce the noise caused by friction caused by road and metal results, and reduce the impact of noise on its drivers.
The above is all about the problems and precautions introduced to you today. I hope it can help you. If you want to know more, you can contact us by phone or follow our website http://www.lutongqixiu.com , our staff will contact you in time.
