Jiangsu Formaldehyde Free Glass Wool Felt Export Glass Wool Aluminum Foil Glass Wool Roll Felt High Temperature Glass Wool Huamei Chemical 3 Glass wool belongs to a category of glass fiber and is a man-made inorganic fiber. Glass wool is a material made by fiberizing molten glass to form a cotton-like material. The chemical composition is glass and it is an inorganic fiber. It has good molding, low volume density, high thermal conductivity, thermal insulation, good sound absorption performance, and corrosion resistance. , chemical properties are stable. The internal fibers of centrifugal glass wool are fluffy and intertwined, and there are a large number of tiny pores. It is a typical porous sound-absorbing material and has good sound-absorbing properties. Centrifugal glass wool can be made into wall panels, ceilings, space sound absorbers, etc. It can absorb a large amount of sound energy in the room, reduce reverberation time, and reduce indoor noise. When centrifugal glass wool is used in buildings, the surface is often attached with certain sound-transmitting finishes, such as plastic films smaller than . Centrifugal glass wool has fine properties such as fire prevention, thermal insulation, easy for cutting, and is one of the most commonly used materials for building sound absorption. However, since the surface of centrifugal glass wool has no decorative properties and fibers are spilled, it must be made into various sound-absorbing components for concealed use. The most commonly used and low-cost structure is the suspended ceiling of perforated gypsum board or the wall of perforated board filled with centrifugal glass wool. When the perforation rate is greater than 1, the sound absorption performance of centrifugal glass wool can basically be fully exerted. In order to prevent glass wool fibers from spilling out, it is necessary to attach a layer of sound-transparent fabric such as non-woven fabric or mulberry paper behind the perforated plate, or wrap the glass wool with glass cloth, plastic film, etc. Panels similar to perforated gypsum boards include perforated metal panels (such as aluminum panels), perforated wood boards, perforated fiber cement boards, perforated mineral wool boards, etc. Glass wool boards can be made into sound-absorbing ceiling panels or sound-absorbing wall panels after treatment. Generally, it is common to cure the periphery of -/3 glass wool board with glue and then wrap it with fire-proof and sound-permeable fabric to form a sound-absorbing wall panel that is both beautiful and easy to install. The common sizes are .×., .×., .×., and thickness. or. There are also sound-absorbing ceiling panels formed by directly spraying sound-transparent decorative materials on the surface of /3 glass wool. Whether it is glass wool sound-absorbing wall panels or sound-absorbing ceiling panels, it is necessary to use high-density glass wool and undergo certain strengthening treatments to prevent the board from deforming or being too soft. This type 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 can generally reach above. In large spaces such as gymnasiums and workshops, in order to absorb and reduce sound, sound absorbers with centrifugal glass wool as the main sound-absorbing material are often used. Sound absorbers can be made into plates, columns, cones or other special-shaped bodies according to requirements. The interior of the sound absorber is filled with centrifugal glass wool, and the surface is wrapped with a sound-transparent surface layer. Since the sound absorber has multiple surfaces to absorb sound, the sound absorption efficiency is very high. In road sound insulation barriers, in order to prevent noise reflection, sound absorption measures need to be taken on the side facing the vehicle. Centrifugal glass wool is often used as the filling material and the surface layer is a perforated metal plate barrier plate. In order to prevent glass wool from absorbing water and getting damp outdoors, it is sometimes wrapped with or plastic film. Sales phone number: Contact person: Manager Gao
