Polyester sound-absorbing board
thickness
1, sound insulation cotton board: gram weight 1.3kg/m2, thickness: 50mm,
1mx2m
2, sound insulation cotton felt: density M2 400g/, thickness: 40mm,
1.44mx20m.
Polyester fiber sound-absorbing plate thickness 9mm, density of 2.25/kg/
square meters. Standard size: 1220 x 2420 x 9mm.
What are the characteristics of polyester fiber board:
1, the sound absorption performance
Acoustic properties of polyester fiber board and other porous materials,
the absorption coefficient increases with the increasing of frequency,
high-frequency sound absorption coefficient, greatly improve the sound
absorption performance of sound-absorbing materials in the back left
cavity and it constitutes the. Noise reduction coefficient of roughly
0.8 to 1.10, become the efficient wideband sound absorbing body.
2, physical and mechanical properties
Polyester fiber sound-absorbing board with sound-absorbing insulation
characteristics, but also in uniform solid material, elasticity,
toughness, wear resistance, impact resistance and tear resistance, not
easy to cut, plate width (9 x 1220 x 2440 mm)
3, product diversity
Polyester fiber sound-absorbing plate has 40 kinds of colors, can be
made into various patterns. The surface shape of a planar, square
(mosaic), wide and thin. The plate can be bent into shape. Can make the
interior design more flexible and changeable, rich effect. Art paintings
can even copy through the computer in the polyester fiber
sound-absorbing board.
4, fire performance
Theaters, dance halls, auditorium, multi-function hall, gymnasium and
other public gathering activities sound-absorbing materials fire
performance is critical. The inspection of the fire parameters by the
national fire protection inspection center of polyester fiber board, the
results show that has good fire performance, comply with the national
standard GB8624B1 requirements.
5, security
The safety performance of polyester fiber board in two aspects, on the
one hand materials with excellent mechanical properties, light weight,
impact damage will not be as brittle materials such as perforated
plasterboard and fiber cement pressure plate, are in danger of falling
debris or debris. On the other hand, the release of harmful substances,
detected by the state departments, the formaldehyde emission standard is
less than or equal to 1.5 mg of /1, the test result is 0.05 mg /1. Meet
the national standard GB18580-2001E1 requirements, in accordance with
the requirements of direct use for interior decoration.
6, clean and simple
Dust removal, easy maintenance. The dust and impurities, vacuum cleaner
and duster flick can. Dirty department can also use a towel to add water
and detergent to wipe. Polyester fiber sound-absorbing board suitable
for opera, theater, studio, recording studio, studio, room, television,
radio, business hall, multi-function hall, conference room, hall, hall,
auditorium, gymnasium, leisure city, hotel, KTV, BAND room, luxury villa
or Home Furnishing life more stringent requirements of the acoustic
place.
