What is car noise insulation cotton

Many friends have just bought a new car and they will add some accessories to the car or dress it up, such as a guard under the engine or car noise insulation. In general, the original factory has been equipped with soundproof cotton for the car.

1, sound insulation cotton has a very good insulation effect of temperature. Therefore, with the sound insulation cotton, the surface of the engine cover can be well protected from rapid aging. Some car owners know that after a long time driving, the temperature inside the engine compartment will be very high, and the cover table paint will quickly age and crack after long-term high-temperature baking. Therefore, we usually find the hood of some cars. Aging loses its luster, while other places are relatively new.

2. When the temperature in the winter is relatively low, the insulation wool can also be well protected. The temperature in the cabin will not drop rapidly, so the temperature in the cabin will not drop abruptly, which can greatly reduce the damage caused by restarting the engine. . In other words, when the engine is kept at normal temperature, frequent start-stop damage is not significant, and if the temperature is too low, frequent start-stop damage is significant. Therefore, the protection of soundproofing cotton will be much less effective.

3, many people will feel that after the installation of sound insulation cotton, will not protect the temperature inside the cabin so as not to distribute the temperature will be dangerous? In fact, this is completely no need to worry, qualified soundproof cotton also has a certain degree of flame retardant Sex. Second, the engine cooling is mainly achieved through the cooling system. Therefore, the insulation wool is only isolated from the temperature and does not increase the temperature.

Xiao Bian concludes: On the above, what is the real effect of car noise insulation cotton ?
