.When we tap a pan directly, we make a very crisp metal tapping sound. If we spray a thick layer of rubber into the pan, we will find that the tapping sound becomes very dull and the sound is obviously lighter. The rubber coated in the iron pan is the damping layer. The same is true in the automotive field: the inner layer of automotive steel plate can achieve the effect of noise reduction and sound insulation by pasting some soft materials. This is the function of automobile damper. It can effectively reduce the vibration of automobile steel plate and achieve quiet effect in the car.
Damping sheet, also known as cement or damper block, is a viscoelastic material attached to the inner surface of the car body. It is attached to the steel plate wall of the car body, mainly to reduce noise and vibration, that is to say, to play a damper role. All cars are equipped with dampers, such as Mercedes-Benz, BMW and other brand cars. In addition, dampers are also used in spacecraft, aircraft and other machinery that need to reduce vibration and noise.
In developed countries such as Europe and the United States, automotive dampers generally use macromolecule resin or rubber materials. As raw materials, these two raw materials will not volatilize toxic and harmful gases.
