The filling of blowing agent must play a certain role in sound insulation, but blowing agent belongs to flammable, used in the high temperature near the engine, I think it is still a little inappropriate. There are many ways to sound insulation, the most simple and effective is to replace the Michelin most comfortable Hao Yue tire, what other sound insulation cotton shock adhesive even if, after all, to remove a lot of things, there will be abnormal sound after removal.
What is a foaming agent
For foaming agent, we are the most common is, when we send it special delivery, send you some fragile, especially, this time because the box is bigger, more space, in order not to let the enclosed items damage inside the running back and forth, when the Courier will be in the white space to spray some foaming agent, after spray in foaming agent soon dry, At this time, blowing agent plays a fixed role, and buffer effect. Simply put, foaming agent is actually foam board.
Are the fins insulated with foaming agent
1. I think the foaming agent of the wing board absolutely plays a sound insulation role. Because I am engaged in the tire industry, I understand that sometimes, it is not necessarily the noise made by the tire, but mostly the noise made by the Rolling Stones and other things hitting the lining of the wing board when the tire is running. If you fill a large amount of foaming agent, you can make the lining of the wing board full. For example, when we hit the empty bottle and the bottle full of water, we intuitively feel that the empty bottle is louder. The bottle full of water is relatively quiet and muffled, so it is definitely useful to supplement the foaming agent.
2. I once removed the taillight of Lufeng X7 car, rear wing plate and bumper filled with a large number of foaming agent, no doubt, this is in order to make the car in a collision, increase the buffer force, on the other hand must be for sound insulation.
Car tire noise is blowing agent effective
Useful, but not much effect, and later for the removal of leaf plate and maintenance of other parts increased great difficulty.
Tyre noise is big, can see if a tire model of this problem, question the Lord you didn't say is what car, what type of tires, such as your bba car, most of them are explosion-proof, of course the noise is very big, because its tires hard, wall thickness, so the noise is big also, this can be addressed by the late replacement tires.
Secondly, if you do not want to change the tire, you can solve it by doing sound insulation, but the sound insulation is professional, not to say that randomly fill the gap inside the sound insulation material. This sound insulation is the most effective, but the price is not cheap, if you use good materials, the price of the vehicle sound insulation from 5000-tens of thousands of different, according to the model and material, the price is very different.
By the way, this extra sound insulation will increase the weight of the car, a better material will be about 200 jin, equivalent to the mass of an adult, so the fuel consumption will increase.
