How to put aluminum foil composite noise?
Aluminum composites: Some of these products will often sound storefront paste under the hood, the hood for paint protection. Due to the high heat reflective foil on performance (up to 95%), and paste this aluminum composite material later, the vast majority of the heat reflected back line has been the engine itself and circulated around the engine, although the effective protection of the paint , is not conducive to long-term stability of the engine, the engine compartment accelerated aging line, easily lead to security problems.
With self-stick material: self-adhesive, also known as gum or stickers, common market, many insulation materials are designed with a self-adhesive, opened behind the sticker material paste can be carried out, the operation is very convenient, this mainly in order to reduce costs and facilitate the construction considerations, because such self-adhesive itself intolerant aging, low intensity, the cold season is easy to crack and brittle hair, in direct sunlight, because of the rapid rise in temperature inside the car in summer vehicle, so quickly soften even gum flowing, pollution body, thereby leading to the loss of open plastic insulation effect, therefore, self-adhesive insulation materials used in the vehicle floor only part of the site. Other parts of the doors, the trunk and the body must be used with caution.
In addition, aluminum foil composite materials are usually not waterproof design, the rain or car washing process will bring the body aggravate problems. Protective equipment should be a good hood insulation, fire-retardant and waterproof design, it is best to have a sound-absorbing effect, with dark skin should be ideal. Aluminum foil in the correct use of the car, for example: high reflection characteristic use of its heat after the other composite materials made of car sun visor or exhaust pipe heat shield use.
