Glass wool belongs to a category of fiberglass and is a man-made inorganic fiber. Using quartz sand, limestone, dolomite and other natural ores as the main raw materials, combined with some soda ash, borax and other chemical raw materials, it is melted into glass. In the melted state, it is blown into floc-like thin fibers with the help of external force. The fibers are three-dimensionally crossed and entangled with each other, showing many small gaps. This gap can be regarded as a pore. Therefore, glass wool can be regarded as a porous material with good thermal insulation and sound absorption properties. Product Properties 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. When centrifugal glass wool is used in buildings, the surface is often attached with certain sound-transmitting finishes, such as plastic films smaller than . . Aluminum foil glass wool and centrifugal glass wool have fine properties such as fire prevention, heat preservation, easy for cutting and are one of the most commonly used materials in 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 cheap 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 plasterboard include perforated metal panels (such as aluminum panels), perforated wood boards, perforated fiber cement boards, perforated mineral wool boards, etc. Other explanations: Glass wool is a porous sound-absorbing material and has good sound-absorbing properties. The reason why centrifugal glass wool can absorb sound is not because of its rough surface, but because it has a large number of tiny pores and holes that connect the inside and outside. When sound waves are incident on centrifugal glass wool, the sound waves can enter the material along the pores, causing the vibration of air molecules in the gaps. Due to the viscous resistance of the air and the friction between the air molecules and the pore walls, the sound energy is converted into heat energy and lost. /Sales phone number: Manager Wang
