Environmental sound-absorbing cotton to
replace the glass fiber and rock wool sponge and other harmful sound-
absorbing material and the development of new products, 100% polyester
fiber, is the closest natural and harmless
to the environment pollution-free high-performance sound-absorbing
insulation material. Environmental polyester
fiber with a special process, it is the biggest difference between the
traditional sound-absorbing material is
environmentally sound, sound-absorbing ability, the product does not
have any odor, harmless to the human body
(no itch), uniform thickness, sound, feel Soft, smooth surface, vertical
and horizontal strong, and its good
sound absorption, noise control project is the best choice for
sound-absorbing material. In Europe and the United
States are the full use of environmentally friendly sound-absorbing
cotton. Sound-absorbing cotton is a man-made
inorganic fiber. Using quartz sand, limestone, dolomite and other
natural ore as the main raw material, with a
number of soda ash, borax and other chemical raw materials into glass.
In the melted state, with the help of
external force into the floc-type flaxation of fine fibers, fibers and
fibers for the three-dimensional cross-
linked to each other, showing a lot of small gaps.
Sound-absorbing cotton polyester fiber Cotton is a synthetic fiber
absorption, China called the polyester, a lot
of clothes are using this material, the advantage is wear-resistant,
easy to clean, bright, shortcomings are not
breathable, wearing a sense of not very good , Can not be directly in
contact with the skin. Sound-absorbing
cotton
What are the advantages of sound-absorbing cotton products? 1,
tasteless, do not release formaldehyde and other
harmful substances 2, anti-aging, wear-resistant, washable, never
deformation, soft, smooth 3, will not rot, can
resist all kinds of microorganisms, fungi, acid, salt and carbon 4,
waterproof, moisture, breathable good 5, in
the production process does not add any additives, adhesives 6,
waterproof, moisture-proof, breathable
performance 7, in the production process without adding any additives,
sticky Glue 8,100% environmentally
friendly products, 100% recyclable 9, high deformation rate 10, strong,
easy to use, easy processing, according
to different needs made into a variety of shapes and long service life
(TB / T2402-1993); 3, the water-repellent rate: 98% (3), the performance
of the sound-absorbing cotton products
which features a noise reduction coefficient of NRC ¡Ý 0.76 (GB 47-83) GB
/ T10299-1988); 4, the water vapor
permeability index is 2.46 * 10-6g / ©O.s.Pa (GB / T17146-1997). 5, the
compression set of 2% (GB / T10295-1988);
Sound-absorbing cotton products use what?
1, instead of sponge for KTV, cinema, dance halls and other places of
entertainment sound-absorbing soft package;
2, for the recording studio, audition room, interrogation room and other
places of acoustic decoration and
decoration. 3, instead of rock wool or glass wool for the light steel
keel gypsum board structure of the light
wall wall; ceiling suction (separated) sound air conditioning duct
suction (interval) sound speaker suction
(separated) sound KTV suction (separated) sound car Suction (separated)
sound mechanical equipment suction
(separated) sound doors and windows suction (every) sound building floor
suction (separated) sound wall suction
(separated) sound
What is the difference between glass fiber sound-absorbing cotton and
polyester fiber sound-absorbing cotton?
??Two products have different sound-absorbing effect is basically the
same,
But the glass fiber is not environmentally friendly, is not easy to
construction, we all know what to get itch, a
little bad flame retardant polyester not, the fire can be incredible,
Than wood also love burning, if you go out is the compound you can use,
you can run out, ah, if the basement of
the karaoke you do not use,
Burning time to choke the dead, we have to talk about what the idea,
polyester fiber glass fiber about 65-105
much cheaper.
Meltblown production of polyester fiber sound-absorbing cotton fiber is
small, is a diameter of 1-4 microns of
ultra-fine fibers and 20-30 microns in diameter composed of short fibers
non-woven materials. Blown melt
processing method can be achieved with more fine fibers made of light,
bulky quality products.
