Tin foil veneer glass wool felt Centrifugal glass wool has excellent properties such as fire prevention, heat preservation, and easy cutting. It is one of the most commonly used materials for building sound absorption. However, because the surface of the centrifugal glass wool is not decorative and there are fibers scattered, it is necessary to make all kinds of sound-absorbing components covertly used. The most frequently used and least costly structure is the ceiling of perforated plasterboard or the perforated wall surface filled with centrifugal glass wool. When the perforation rate is greater than 20%, the sound absorption performance of centrifugal glass wool can be fully exerted. . In order to prevent the glass wool fibers from spilling out, a sound-permeable fabric such as non-woven fabric, mulberry paper or the like may be attached behind the perforated plate, or a glass cloth or a plastic film may be used to wrap the glass wool. Similar to the perforated plasterboard panel are perforated metal panels (such as aluminum), perforated wood, perforated fiber cement board, perforated mineral wool board.
Glass wool board can be processed into sound-absorbing ceiling panels or sound-absorbing wall panels. Generally, 80-120kg/m3 glass wool board is cured around the periphery of the glass wool board, and the fireproof sound-permeable fabric is outsourced to form a sound-absorbing wallboard that is beautiful and convenient to install. The common size is 1.2m×1.2m, 1.2m×0.6m, 0.6m×0.6m, thickness 2.5cm or 5cm. There are also sound-absorbing ceiling panels formed by directly spraying acoustically transparent decorative materials on the surface of 110 kg/m3 of glass wool. Whether glass wool sound-absorbing wall panels or sound-absorbing ceiling panels, high-consistency glass wool is required, and a certain amount of strengthening treatment is performed to prevent deformation or excessive softness of the panels. This kind of building materials not only has good decorative properties but also retains the good sound absorption properties of centrifugal glass wool. The noise reduction coefficient NRC can generally reach 0.85 or more.
Glass wool is a category of glass fiber. It is a kind of artificial inorganic fiber. Quartz sand, limestone, dolomite and other natural ores are the main raw materials. With some soda ash, borax and other chemical raw materials melted into glass. In the melting state, with the help of external forces. The blow-type is thrown into flocculent fine fibers, and the fibers and fibers are crosswise. Entangled with each other, showing a lot of small gaps. This gap can be seen as a pore. Therefore, glass wool can be regarded as a porous material, with good thermal insulation and sound absorption properties. In large spaces such as gymnasiums and workshops, sound absorbers using centrifugal glass wool as the main sound-absorbing material are often used for sound absorption and noise reduction. Acoustic absorbers can be made into plate, columnar, pyramid or other profiled bodies as required. The sound-absorbing body is filled with centrifugal glass wool and the surface is covered with an acoustically transparent surface layer. Since the sound absorber has multiple surface absorptions, the sound absorption efficiency is high. In road noise barriers, in order to prevent noise reflections, it is necessary to take sound-absorbing measures on the side facing the vehicle, and often centrifugal glass wool is also used as a filler material and the surface layer is a barrier plate of perforated metal plates. In order to prevent glass wool from absorbing moisture in the outdoors, PVC or plastic wrap is sometimes used.
