Shanghai glass wool wholesale price glass wool roll felt manufacturer glass wool price Huamei glass wool glass wool belongs to a category of glass fiber 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. 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. 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
