Construction Technology of Soundproof Cotton

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 absorbing body, etc., can absorb a large number of room sound energy, reduce reverberation time, reduce indoor noise. Centrifugal glass soundproof cotton Bulk density: 12-35kg / m3 Centrifugal glass Soundproof cotton fiber Diameter: <8¦Ìm Centrifugal glass soundproof cotton Thermal conductivity: ¡Ü0.039-0.042w / mh ¡æ (thickness related) Centrifugal Glass insulation cotton Specifications: 120cm * 800cm * 8cm


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.
