Noise pollution is also a kind
of pollution. Because every family lived very near modern,
sometimes
some noise will cause trouble between neighbors. How can we put
an end to these problems? It is a
good way to use the sound insulation materials. What are the
indoor sound insulation materials?
Indoor sound insulation material to choose what is the matter?
First, indoor noise materials which have
1, sound insulation felt
How to choose indoor sound insulation materials
Sound insulation felt
Sound insulation felt is the current market better room noise
material. Mainly used in combination
with gypsum board for wall insulation and ceiling noise, but
also used in pipe, mechanical
equipment, noise and vibration damping. Not in the soundproof
felt felt, look completely different,
felt light and soft, while the sound felt thin but very heavy.
The soundproof felt tasteless EPDM rubber and ten kinds of
organic minerals according to a certain
proportion of refined product is black, green no smell, a good
sound insulation materials of low
frequency and high frequency sound has spread, can effectively
restrain the vibration, the material
thickness of 1mm, 2mm, 3mm range, by the State Bureau of
building materials detection, isolation of
Rw volume weight were 23dB, 27dB, 30dB, material flexibility is
also very good, can be arbitrarily
bent, cut the ribbon, very convenient construction and fire
insulation materials.
Sound insulation felt has the following advantages:
(1) light and thin material
(2) soft, tensile strength
(3) environmental protection, does not cause the pollution to
the environment
(4) suppression of the propagation of low frequency sound waves;
excellent flame retardant
properties
(5) convenient construction
2, polyester fiber board
How to choose indoor sound insulation materials
Polyester fiber acoustic board
It is an ideal indoor sound insulation material. The raw
materials of polyester fiber 100%, with
sound-absorbing, environmental protection, flame retardant, heat
insulation, thermal insulation,
moisture-proof, anti mildew, easy removal, easy cutting,
parquet, simple construction, good
stability, good anti impact ability, independence, cost
advantages, has a rich variety of colors
available, which can meet the acoustic decoration the demand of
different styles and levels. Mainly
used in movie theaters, concert halls, museums, galleries,
libraries, galleries, auction hall,
room, gymnasium, hall, multi-function hall, hotel lobby,
hospitals, shopping malls, schools, piano
room, conference room, studio, studio, KTV rooms, bars,
building, room, family noise reduction and
high requirement of high-grade decoration places on the acoustic
environment.
3, wave absorbing sponge
How to choose indoor sound insulation materials
Wave absorbing sponge
The indoor sound insulation material wave absorbing sponge, it
is a kind of special sponge after
processing equipment to form a convex wave shape, which is
filled a small gap and semi open pore
structure, can absorb a large number of acoustic energy into the
attenuation to the role of sound
waves, reduce indoor reflections and reverberation interference,
improve the purity of the sound.
Main performance characteristics:
(1) the sound absorption rate is high
(2) good heat insulation
(3) difficult to burn grade B1
(4) the structure is close, and the shape is stable.
(5) light weight, construction safety and convenience
(6) harmless to the human body, no pollution to the environment,
no smell
(7) water, water drainage is strong, sound-absorbing performance
is not reduced, no change in the
form of
(8) can be used for the two time, two times destroyed easily, no
pollution to the environment
Two, indoor sound insulation materials to choose to pay
attention to matters
1, sound insulation window to buy

How to choose an indoor sound insulation material
Look at the material: including aluminum, glass, hardware, color
is consistent, hardware parts
assembly is complete.
See processing: high quality aluminum alloy window, processing
fine, tangent smooth, angle of the
agreement (the main frame is usually 45 degrees or 90 degrees),
in the splicing process should not
appear more obvious gap, switch smooth.
See glass: to see whether it is a hollow glass, there is no
coating, plating on the composite film
in general corrosion resistance, wear resistance, high gloss.
See size: check whether the window size is correct.
2, sound insulation door to buy

How to choose an indoor sound insulation material
Look at weight: sound insulation formula and the density of the
material has a direct relationship,
so the density of the sound insulation is relatively good,
relatively light, this is the source of
the noise is not good. But the attention: the middle of the flat
plate hollow door and the sound
insulation cotton will be even more noise than the solid wood
door.
Watch the thickness: the thickness of the surface layer, the
better the effect of noise insulation.
General wooden doors of the use of the surface layer should be
8mm thick. The thickness of the
surface layer is also better, but the cost will be higher. But
the tin surface layer: 3mm thick
iron fire door, sound insulation effect is good.
See: the smoothness of the flat wooden doors, Mentao combination
with better, but no matter what
the structure. As long as the deformation of the wooden doors
sound insulation certainly not.
The technique of selecting the sound insulation door: the door
of the main door of the sound
insulation door, mainly depends on the inner core of the filling
material. Generally speaking,
molded soundproof door inner core is filled with paper base
honeycomb structure, it formed a closed
air layer can play the role of good sound insulation.
