Polyester fiber sound-absorbing decorative plates with the role of acoustic, quiet, noise, flame retardant, thermal insulation, thermal insulation, the material is uniform and solid, not only elastic, toughness, wear resistance, impact resistance, not easy to cut through, and the cavity constitutes the sheet resonance absorber is very effective, is a high bandwidth efficient sound-absorbing material. In addition, the polyester fiber sound-absorbing decorative plate light, excellent material properties, unlike some brittle materials such as perforated plasterboard and cement fiber pressure plate to produce a risk of falling debris or fragments exist, formaldehyde and 0.05 mg / 1 emission standards, but also far less than the state regulations formaldehyde emission of less than or equal to 1.5 standard instead of the past, laminate plus the new acoustic material of the sponge or glass fiber, and easy to destroy does not pollute the environment, recyclable. 

 Polyester fiberboard sound-absorbing principle: the materials within a large number of tiny connected porosity, sonic depth inside the material along these pores can with the material friction effect the sound energy into heat. A porous sound-absorbing material, sound absorption characteristics is gradually increasing absorption coefficient with increasing frequency, high-frequency absorption which means that low-frequency absorption. A necessary condition for sound absorption of porous materials: a large gap materials, gaps between interconnected pores within the in-depth material. Misconceptions that the surface roughness of the material has a sound absorption performance, In fact, such as napping cement surface of convex and concave stone basic does not have a sound absorption capacity. Misconceptions that material within a large number of holes in materials such as polystyrene, polyethylene, closed-cell polyurethane, with good acoustic performance, In fact, these materials due to internal pore connectivity, sound waves can not be in-depth material internal vibration friction, absorption coefficient is small 
 The sound absorption mechanism of polyester fiberboard with the cavity of the body constitute the structure of the absorber sheet resonance sound absorption. Plate severe vibration in the resonance frequency, a substantial absorption of sound energy. Have good sound absorption performance in low and high frequency. 
 Applications: Polyester fiber sound-absorbing decorative plates can be used for home theater, hotels, dance halls, nightclubs, KTV rooms, concert halls, function rooms, studios, recording studios, theaters, offices, meeting rooms, indoor recreation centers, libraries, exhibition hall, classrooms, training centers, interrogation room ... indoor places. 

 Specifications: 1220 * 2420 * 9mm 

 Polyester fiber acoustic panel construction method: 

 1, pre-construction, attention to the election board, the plate arrangement, to avoid the slight color difference. Sound-absorbing panels of polyester fiber, polyester fiber raw materials, formed by hot pressing, due to different production batch number and polyester fiber coloring is extremely difficult, under the action of the sun, easy to produce a slight color difference; in the purchase to make the same batch production of polyester fiber acoustic panels, pre-construction, the polyester fiber sound-absorbing panels plate arrangement, adjust the color, then adjust to the good order of the installation and construction. 
 2, cutting board to use the rigid on foot 
 Needs in the construction of polyester fiber sound-absorbing board cutting, when cutting is recommended to use a steel ruler or alloy square steel as on foot, do not use strips of wood or soft materials as on foot, to avoid cutting the lines do not directly caused by splicing gap is too large or distorted. Splicing gap relative reduction can be cutting blade inward tilt 0.5 ~ 1mm, so that the interface surface to the formation of the Inner Bevel, construction, easy to board the face then to reduce the gap degrees. 
 , Cut with a blade in the down side, we recommend the use of imported blade 
 Due to domestic knife and quality of steel, the blade is not sharp and short life, cutting or down side is easy to produce burrs and rough surface, especially in the down side, the rough surface, the down side the best use of this product special inverted edge plane. 

 4, the substrate processing 
 1) should be substrates of the hole substrate splicing gap seam tape with stickers affixed real 
 2) perforation substrate inside of the substrate with a thin film hole closed 
 5, paste glue choice 
 1) First, consider the use of glue to meet the requirements of the State Environmental Protection 
 2) According to paste the base surface can choose different types of adhesives 
 3) cement or wood base surface: choose chloroprene rubber as raw material benzene-purpose adhesive, or one hundred latex 
 4) gypsum board base side: under the premise of difficult to wet, the choice of one hundred latex or cellulose as raw material wallpaper glue (gluing paste immediately with a nailing pattern, to avoid the glue is dry, the board move ), can choose easy or possible to damp the premise, all-purpose adhesive 
 6, the polyester fiber acoustic board is a porous plate, can easily absorb the glue to plug the holes, it is recommended that the construction can be single-sided gluing (only in the wall gluing, gluing than normal and slightly heavier). Can also be accompanied by the shank nails reinforcement 
 7, Yin Yang angle processing 
 Polyester fiber acoustic panels, do the Yin Yang angle processing, its methods and aluminum composite panel construction method 
 Cleaning related issues: 
 There are three main polyester sound-absorbing panels of stains encountered in the construction 
 (1) ash, dust. The direct use of the scrubber surface dust collector 
 (2) mud stains. Use water to wet the polyester fiber acoustic panels, high water absorption of the scrub material with weak alkaline foam cleaning agent to clean 
 (3) oil stains and rust stains, use a dedicated, rust agent cleaning (you can choose the car used for degreasing rust remover) and
