In the field of home decoration, sound-absorbing and soundproof cotton is still widely used, which can effectively block noise and make family life more comfortable. But sound-absorbing cotton and soundproofing cotton are two different materials, with obvious essential differences. Do you know?
Opposite sex sound-absorbing sponge
1. Different materials. Nano sound-absorbing sponge is a porous foam made of melamine resin foam. The sound will weaken and disappear after passing through the sound-absorbing cotton, and it will not reflect back; And soundproof cotton is mostly made of rubber material and has a closed cell structure. Although it can block the transmission of sound, it is easy to cause sound reflection.
2. Different functions. Sound absorbing cotton has many pores on its surface, which can play a role in sound absorption and noise reduction, and can also convert sound into heat energy. The main purpose of soundproofing cotton is to block noise. Most soundproofing cotton reflects noise rather than absorbs it. This is the fundamental difference between sound-absorbing cotton and soundproofing cotton.
1. Sound absorption: The three-dimensional opening of the nano sound-absorbing sponge reaches 98%, making it convenient and effective for sound waves to enter the sponge, emit back and forth within the sponge, consume the potential energy of sound, and achieve the function of noise reduction.
2. Heat resistance: Nano sponge does not require the addition of other flame retardant media, and can quickly decompose and carbonize in the presence of open fire, without generating dripping. The smoke density is less than 15, and it can achieve B1 level flame retardancy.
3. Thermal stability: Nanosponges belong to thermosetting plastics, with a high cross-linking structure system, good thermal stability and aging resistance, and can withstand high peaks up to 240 ℃, making them less prone to deformation.
4. Good post processing ability: Nano sponge foam can be made into sheets and profiles through machine processing to produce items that meet different needs in different places.
5. Health and safety: Nano sponge is green and environmentally friendly, without fibrosis, effectively protecting the natural environment and human health. The main raw material, melamine resin, can be used to clean tableware.

The choice of sound-absorbing cotton and soundproofing cotton mainly depends on where you want to use it and what effect you want to achieve.
1. To reduce indoor sound reflection, reverberation, and noise interference, it is necessary to use sound-absorbing cotton materials to create space absorbers, sound-absorbing fiberglass ceilings, and fabric sound-absorbing boards, optimizing the indoor acoustic environment, such as theaters, cinemas, KTVs, and other places.
2. If you want to isolate external sound, maintain a quiet indoor environment, and maintain uninterrupted living and work, you need to use soundproofing cotton materials, such as soundproofing walls, soundproofing cabinets, soundproofing filling cotton, etc., which greatly improves the soundproofing and insulation performance of walls, floors, spaces, and other structures, creating a private, quiet, and comfortable activity space.
