1. Sound insulation felt
Sound insulation felt is a kind of flexible high-density rolled material made of elastic materials such as rubber and plastic as the main raw material. It is mainly used for Paired with gypsum board, it is used for wall sound insulation and ceiling sound insulation. It is also used for sound insulation and damping of pipes and mechanical equipment. The application scope of sound insulation felt is put in layman's terms.
As long as it is used for sound insulation measures, it can be used. For example, sound insulation felt and gypsum board can be used to make sound insulation walls. Sound insulation felt is also used for ceiling sound insulation. It is also used for sound insulation of pipelines and mechanical equipment. and damping. Therefore, the sound insulation effect of sound insulation felt is beyond doubt.
2. Sponge
Sponge is a very good sound-absorbing material. Sponge is usually used in large quantities in recording studios to achieve sound insulation. Sponges with sound-absorbing grooves on the surface have better sound-absorbing effects. This kind of sponge is often called corrugated cotton.
It’s just that sponges have strong water absorption capabilities and are easy to absorb dust. If used as sound insulation materials for windows, they will easily absorb water on rainy days or when wiped with a wet cloth, causing the iron frames on the windows to rust.
3. Polyurethane foam
Polyurethane foam is the main component of styrofoam. Cured polyurethane foam materials can have good sound insulation and sound-absorbing properties, and are anti-corrosion and waterproof. Moreover, better polyurethane materials have flame-retardant designs, making them a good choice for sound insulation materials.
4. Calming soundproofing and sound-absorbing cotton
Calming soundproofing and sound-absorbing cotton uses industrial rubber and plastic as the carrier, adds sound-insulating particles of various specifications, is foamed with nitrogen, and has a gray-black appearance. Its front is covered with micro sound-absorbing holes and special-shaped sound-absorbing grooves, which effectively filter noise of different frequencies and wavelengths. It integrates sound insulation and absorption functions, meets the requirements of lightweight and environmentally friendly home decoration sound insulation materials, and is very cost-effective.
5. Soundproofing and damping felt
The soundproofing and damping felt is made from a variety of organic minerals in a certain proportion by introducing advanced foreign technology. The soundproofing felt has good wide-band sound insulation performance and high Damping performance is a new type of sound insulation material that controls the attenuation of noise in the transmission path.
After mixing high-density special materials, a very good sound insulation and noise reduction effect is achieved, so that the sound insulation felt shows excellent performance in isolating air sound and impact sound. The sound energy is lost inside the sound insulation material. For The isolation effect of medium and low frequency noise is unmatched by other materials, and it is an excellent multi-purpose sound insulation material.
