Sound insulation cotton Description:
Sound insulation cotton (scientific name of centrifugal glass wool) is
an ideal sound insulation and thermal insulation materials, widely used
in housing wall insulation, ship engine room insulation; computer room
noise, cold storage temperature; Room noise, pump noise; sound cabinet
noise, sound and other noise adjustment. Sound insulation coefficient:
glass wool felt, sound-proof cotton felt for sound-absorbing material
used in the back of the air layer or paste the surface decoration
materials. In the air layer thickness of 100-150mm range, the thicker
the air layer, the middle and lower bass sound insulation rate is
higher, such as air thickening to 300mm, the effective sound insulation
rate range expanded to 100Hz. 1st-acoustics Sound insulation cotton
Usage: Function: Wall sound-absorbing, wall insulation, wall insulation,
wall insulation. Sound insulation cotton sound insulation principle:
centrifugal glass sound insulation cotton internal fiber fluffy
staggered, there are a lot of tiny pores, is a typical porous sound
insulation material, has good sound insulation properties. Centrifugal
glass sound insulation can be made of wall panels, ceiling noise, space
absorption body, etc., can absorb a large number of room sound energy,
reduce reverberation time, reduce indoor noise. Centrifugal glass sound
absorption characteristics of sound absorption not only with the
thickness and bulk density, but also with the cover material, structure
and other factors. In building applications need to take into account
the cost, aesthetics, fire, moisture, dust, anti-aging and other issues.
Centrifugal glass wool is porous sound insulation material, has good
sound insulation performance. Centrifugal glass sound insulation to
sound absorption is not due to surface roughness, but because of a large
number of internal and external connectivity of small pores and holes.
When the sound waves into the glass on the sound insulation, the
acoustic energy along the pore into the interior of the insulation
material, causing air molecules in the gap vibration. Due to the viscous
resistance of air and air molecules and pore wall friction, sound energy
into heat loss. Sound insulation cotton is the use of sound insulation
in a longer time noise insulation materials, sound insulation industry
with the soundproofing technology continues to develop and mature, the
noise of the increasingly rampant, noise cotton in the building
materials market is not uncommon. Noise cotton see more not necessarily
understand how much it, the grand sound insulation to simple to
introduce you to the 1st-acoustics magnificent sound insulation cotton
and its use. Sound insulation cotton species: 1st-acoustics magnificent
sound insulation cotton professional production and marketing grand
sound insulation cotton, cotton insulation, Henan, 1st-acoustics noise
cotton. Magnificent customer service staff to provide 1st-acoustics
noise cotton price advice, noise treatment and troubleshooting questions
and so on. Magnificent sound insulation cotton main products are
1st-acoustics noise blankets, 1st-acoustics noise cotton, 1st-acoustics
soundproof windows, ktv noise insulation materials, sound insulation
board, acoustic walls, polyester fiber sound-absorbing panels and so on.
1st-acoustics sound-absorbing cotton internal fiber fluffy staggered,
there are a large number of tiny pores, is a typical porous
sound-absorbing material, has good sound absorption characteristics.
Centrifugal glass wool can be made of wall panels, ceilings, space

1st-acoustics sound insulation cotton nine advantages: 1. Excellent
insulation properties and noise absorption properties, can effectively
prevent sound transmission 2. Lightweight and efficient, to reduce the
construction load 3. Fiber slender, non-slag ball, the use of Long life,
anti-vibration and better sound absorption, higher durability 4.A1-level
fire, permanent non-combustible 5. Low moisture absorption, physical
properties and stability 6. Intensity of the surface can be a complex
multi-veneer 7. Antimicrobial Mildew, anti-aging, anti-corrosion to
ensure a healthy environment. 8, convenient storage and transportation,
cost savings 9. Installation faster, more simple construction, free
cutting. 1-st acoustics cotton, 80KG / 50MM or 96KG / 25MM (two-use)
high-density sound insulation glass wool board, the installation
requires manufacturers to use dust cloth wrapped with a good glass
before the first-acoustics, Cotton, glass fiber, easy to install, fast,
clean, no residue after installation of the material in order to install
immediately after the use of space. 2,1st-acoustics noise blanket, 3.0MM
thickness of the best, followed by 2.0MM thick. Gypsum board
Thick layer) with two layers of gypsum board, the first layer of noise
in the installation of cotton after sealing, the second layer on the
surface.
