Descripción del producto
1, polyester fiber is sound-absorbing board product is mainly
used in indoor (metope, ceiling)
2, polyester fiber is sound-absorbing board is a porous material,
magnified three hundred times as much to talk, we see the
polyester fiber is sound-absorbing board is porous structure, it
is because these cavity, polyester fiber is sound-absorbing board
can sound-absorbing (voice after polyester fiber sound-absorbing
panels in cavity formed by sound energy into backflow, heat).
3, decoration plasticity, use common wall paper knife, it can
cut.
4, polyester fiber materials, what is polyester fiber (PET),
polyester fiber material is oil chemical materials, commonly
known as the polyester, is in the state of wire drawing, color
after pressing into boards.
5, has sound-absorbing, fire prevention, environmental
protection, noise reduction, moistureproof, characteristics,
sound-absorbing, fire prevention, environmental protection for
instructions
(1) polyester fiber is sound-absorbing board sound-absorbing
mainly reflects in sound-absorbing noise reduction coefficient,
according to GB/T*********6, average noise reduction coefficient
(NRC) of 0.*5 above, average absorption coefficient (**0 HZ ac*4
KHZ) was 0.*2. In the high frequency band, for better effect.
(2) polyester fiber is sound-absorbing board for national fire
protection GB***4 B1 level (***7) national fire protection has
four grade level A: doesn't burn. (like stone, steel, etc) B1
level: flame retardant. (mainly refers to fire left the fire
spread speed slow) B2 class: flammable (as long as it's wood,
etc.) B3 level: flammable (alcohol, fuel)
(3) environmental protection level is divided into: E0 level, E1,
E2 class
Polyester fiber is sound-absorbing board far accord with a
country (the gb*********1) E1, formaldehyde to release a quantity
to < 0.1 (mg/l), index more than 1.5 mg/requirements (l) ,
which can be directly used for indoor
Fields: home cinema, hotel, studio, the music room, KTV, bars,
theaters, meeting rooms, multi-function hall, the indoor stadium,
