To get away from the noise, we can do
is sound and sound. Can play a sound effect material though many, such
as glass cotton, wool, sponge, polystyrene perlite can solve the noise
problem, although they are in our space, our lives buried a security
risk, such as glass wool, rock wool, it will cause skin itching,
respiratory allergies. Sponges, etc. are flammable products, and in the
combustion process will produce toxic gases.
Jing Cheng environmental protection sound-absorbing cotton,
sound-absorbing effect and excellent safety performance favored by the
majority of users, our company introduced a new production method,
static protection sound-absorbing cotton with 100% Cheng imported
polyester fiber, using layered lamination, strictly control the
overlying pressure, good absorption effect of various frequency noise
are. It solve the ordinary polyester fiber sound-absorbing cotton can
only eliminate the voice of high frequency sound limitations, for
electrical appliances, ground and wall vibration, and the low frequency
sound mopping slippers good absorption, and it is a kind of efficient
sound-absorbing cotton. It is widely used in wall, ceiling, floor, sound
insulation and sound equipment. Its performance is excellent, the other
is sound-absorbing material can not match. It has high safety, high
efficiency is the most close to the natural acoustic insulation
materials and is harmless to the human body without pollution to
environment. It is not applied any glue production process, making full
use of its own characteristics and temperature control of melting,
forming, so the product does not contain formaldehyde, as proved by the
long-term experiment and practice, it does not have any allergies to
human skin. Difficult to burn products, any indoor places can be used.
The acoustic performance by the national authoritative department, the
performance is very excellent in acoustic material, the raw material for
the flexible fiber, no weathering, no pulverization, acoustic
performance will never decay, is the product of choice for your sound
absorption, sound insulation, sound deadening.
Product Description: environmental protection is a static
sound-absorbing cotton and the development of new products to replace
the glass fiber, wool, sponge and other harmful sound-absorbing
materials, by making 100% polyester fiber made by hot pressing after
made cocoon cotton like. To realize the diversification of density by
means of heat treatment law, make it become the sound-absorbing
material, decorative material. Excellent products in insulation
materials. It does not contain glue, so there is almost no volatile
matter. It is made up of two kinds of polyester fibers with different
melting points. In the production process, when the oven is heated to
the melting point of the low melting point fiber, the low melting point
fiber is melted into an adhesive. The environmental performance is its
biggest advantage, the detection data reaches the national E1 level
evaluation is able to direct contact with human body, is the most
efficient acoustic insulation materials close to natural and harmless to
human body and no pollution to environment. Its fire performance is B1
level, is difficult to burn products. The sound-absorbing performance
has been recognized by the majority of acoustic experts. Comprehensive
use of environmentally friendly sound-absorbing cotton in Europe and the
United States, for piano room, machine room, conference room, gymnasium,
music room, studio, highway noise walls and other public places, replace
the glass fiber and wool sponge and other harmful sound-absorbing
material.
