Product introduction: aluminum foil insulation cotton car is mainly to designthe barrier outside light and heat of the engine， can be used in the car， in the car door， car plates， roof， hood mounted a layer of heat insulation cotton， which blocked the heat outside also has sound insulation effect，various kinds of aluminum foil composite， strengthen the insulation effect，reduce heat absorption. Automotive aluminum foil insulation cottonappearance is beautiful， simple and convenient construction， generalspecification is 1M*10M， can be customized according to customer requirements， product also has a safety and environmental protection，tasteless non-toxic， waterproof anti-corrosion， weather resistance， good flexibility， bent， with self-adhesive， tore off the brown paper pasted

Products with aluminum foil and strong adhesive without additional buy glue.A well stocked without consultation， to ensure quality and delivery speed.(not flame retardant， please do not use open flame test)

As is known to all， vehicle noise at idle， acceleration or different roadcondition and produces， the chassis and carbody resonance or resonantafter the noise amplification and into the car， so that occupants feeldiscomfort. Because sound travels through vibration. So is the use ofprofessional sound engineering acoustic products and car body vibrationabsorption， is separating from the transmission noise. Soun. Sound engineering mainly handled through the following two ways:

(1) the use of damping sound insulation materials to achieve the silencingand noise reduction. For example: in the door， chassis is stuck anddamping sound insulation material， it will play a resonance reinforced body structure and the controlling body and external noise effect. This is because the paste damping sound insulation materials. To change the natural frequency of the body， control resonance and resonance of external vehicle noise and the car body， so as to effectively remove the vehicle noise.

(2) absorbing materials to achieve the silencing and noise reduction. For example: in the engine compartment lid using sound-absorbing materialafter the engine's noise significantly decreased. This is because the sound absorbing material is a kind of acoustic foam， which level distribution ofopen cavity and closed cavity， can effectively separate the noise thatacoustic energy into mechanical energy and heat energy consumed， so as to achieve the purpose of absorbing noise

The use of these two kinds of materials are not independent， will be used in conjunction with best results.

This product is with aluminum foil! Thickness of 10MM! Do not compareother than the material and thickness and our.

Car sound engineering to engine noise， vibration， vehicle door resonance，driving and road， air resistance friction sound， effectively eliminate and barrier， give you a quiet driving space， greatly improve the driving comfort.

Body cover， door， the reserve tank， roof， the wing non critical parts of sheet metal sheet are relatively weak， adding soundproof material， body stronger，collision， passive safety coefficient is improved.

Sound， especially a rear mounted subwoofer， will lead to the trunk vibrationreduction， sound， this is because did not have proper damping， the automobile structure could not bear the overweight bass impact， issued a "squeak" sound. After construction noise， eliminate the resonance bodymetal， but also has sound-absorbing effect good， can feel the sound moreclear， vigorous， surging.

Why use insulation cotton?

1 prevent engine heat into the engine cover， thereby protecting hood paint，

2 role is to absorb engine car noise. To control the front side (including firewall) sound-absorbing cotton is absorbing engine to the noise inside the car， your car should have a firewall on the sound-absorbing cotton， this isthe standard， and only high-end car engine cover with cotton.

Sound insulation:

1， a machine cover

Most front cover are the 4 screws in the body， also has a hydraulic tappet，pipeline to dismantle the several screws and connecting the wiper cleaningnozzle， can remove the front cover， need two people at the same time with the demolition， take care not to damage the front windshield glass. Removeand put on cotton insulation to prevent scratch， some original car engine cover with perhaps a small cotton insulation， we generally demolition waste，because it is too small. Play the role of very little. A clear front cover do noise， generally no oil. Use a wet towel to wipe clean and cool dry， to stopshaking board according to the shape of groove machine cover， cut a pointabout the big stick in the groove parts machine cover， check the shaking board more out of the plug into the gap to cover panel reinforcement andmachine the inner， compacted by hand， this is because the more is not easy to fall off， and then cut a machine cover is slightly larger than the whole insulation cotton double-sided brush adhesive on the front cover， by hand from the centre to the periphery of compaction. The bubble out， this one is very important， otherwise the insulation cotton is easy to fall off. With the new wallpaper knife in the edge of the cover from the machine to 1 centimeters place cutting edge， the cutting edge of Qi to beautiful， the remaining 1 centimeters to affix the sealing strip used. The pipe joint wiperwater spray nozzle to stay out for loading plug， so that the hood iscompletely done. He played a protective paint， shielding the engine soundeffects， of course， is on the outside to listen. There are many friends asked，Is it right? Such engine heat， automobile engine is now the water， is to rely on water tank and a cooling fan to heat， and this has nothing to do. The whole car generally use cotton insulation 8-14 meters， 5-10 meters stopvibrating plate. To a lot of difference with cotton insulation effect， we havedone a lot of cars， the effect is not good， is also a lot of people have suspected causes of noise.

2， U shaped groove

Fixed screw removal wiper， under the sway， can take the rain brush arm，and then remove the U slot cover， the cover screw fixed， but also useful for plastic clip， try not to remove the bad， and the bad in buy， anyway also notworth. Then remove the wiper motor and linkage rocker mechanism， the caris also 4， 5 screws， pull the plug connection wiper motor open win， also is to first clean the U slot， the check
