The reason why the noise is
used in the car engine is because it has a unique performance.
First of all, such a noise insulation, there is a heat
insulation effect, for the automotive engine is an indispensable
auxiliary material. When the engine is used for a long time in
order to avoid the engine's internal heat conduction to the
engine cover affect the performance of the body, is to use a
sound insulation cotton stick to the engine cover around the
protection up.
Why is the effect of sound insulation cotton to produce so
obvious? So now we have to mention the production of material on
the insulation cotton. Sound insulation cotton is a kind of
multi fiber structure. When the sound is transmitted in the
fiber structure in the continuous vibration transmission. Master
multi fiber material can produce numerous times of refraction,
in the continuous impact of the fiber structure, and finally
transformed into the sound absorption of heat after impact. So
the sound is gone after the effect of the sound insulation.
In addition to the car's engine noise in the car in the car will
also be used in. Because once the car there are many parts of
the ring sound in launch time, but if the installation on cotton
insulation in the body some noisy sound was immediately reduced
to the driver is a kind of protection. Besides being able to
reduce the noise to the car, we can also effectively protect the
interior of the car. If there is noise or impact wear, cotton
will have some relief, thus making a life extension benefits of
body parts. In addition to protect the car parts, insulation
cotton also has waterproof performance, when the car is exposed
in the air is also subject to corrosion from the environment,
but can protect car insulation cotton good parts..
