Shangqiu centrifugal glass wool price Aluminum foil glass wool roll felt Aluminum foil glass wool board 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. 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. Internal structure: The internal fibers of centrifugal glass wool are fluffy and intertwined, with 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. 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
