Polyester sound-absorbing panels,
composed of 100% polyester fiber as raw material after hot pressing made
of cotton cocoon shape; to achieve diversity density to ensure
ventilation by heat treatment law, making it an excellent product
finishes, sound-absorbing, heat insulating materials, has the advantages
of simple construction, strong decoration, style, rich colors and other
advantages, can be direct decorative surface materials, also can do all
kinds of paint spraying according to different needs, which can replace
the existing laminate with sponge or glass fiber cloth of the
traditional soft bag.
Polyester fiber sound-absorbing panels, and other similar acoustic
properties of 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;
noise reduction coefficient of roughly 0.8 to 1.10, to become the
efficient wideband sound absorbing the sound absorbing body body; which
in addition to high sound absorption coefficient and absorption
frequency width of the acoustic performance, but also has indoor
physical and mechanical performance, good performance.
The safety performance of polyester fiber sound-absorbing panels in two
aspects: the mechanical properties of a material excellent, light
quality, impact damage will not be as brittle materials such as
perforated plasterboard and fiber cement pressure plate to produce
fragments or pieces of exist in danger of falling; on the other hand,
the release of harmful substances, by the relevant departments the state
detection, 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.
The use of polyester fiber board
Polyester fiber sound-absorbing board material can make indoor shape
design more flexible, rich, and even art paintings can copy through the
computer in the polyester fiber board, widely used: conference room,
television, studio, theater, audio-visual, opera, leisure entertainment
city, hotel, multi-function hall, music hall, bar, restaurant, shopping
malls and so on. The operation of polyester fiber sound-absorbing board
installation professional construction personnel to operate, pay
attention to the following aspects:
1 polyester fiber panels, with 100% polyester fiber as raw material,
after hot forming, due to different production batches of colored silk,
in the light of the role that is easy to produce small color difference,
at the time of purchase to use polyester fiber sound-absorbing board
production with the same batch number, prior to the construction of the
polyester fiber panels are arranged in rows, adjustment the color and
then press the adjust order of the installation (the best load gloves to
avoid pollution of construction);
2 in the construction of polyester fiber panels for cutting, recommend
the use of steel or alloy steel as ruler cutting (do not use wood or
soft material as ruler) to avoid cutting straight lines caused by
splicing gap is too large or distorted;
3 for the splicing gap is relatively reduced, while cutting blade can be
appropriately tilted inward 0.5~1 mm, the interface is easy to form an
inclined plane, construction board docking, reduce the gap degree;
4 because of domestic art blade steel quality and other reasons, the
blade is not sharp and short service life, easy to produce burr and
cutting edge or in the hair surface, especially in the hair surface edge
produced obvious, so the best use of high-quality imported blade;
The base surface should be smooth, the cement base paste, surface
finishes should be smooth, and then paste polyester fiber
sound-absorbing board; in case of basic cavity after, should be the
first strip with a splint splicing gap (or tape) paste. In the case of
perforation plate base, should be the perforated panels before
installation of the hole (can be used inside film method etc.). In order
to avoid air flow below the base smear.
