Sales hotline 3 Manager Wang Glass wool insulation board manufacturer mainly produces and sells glass wool series insulation materials, glass wool board, glass wool, glass wool roll felt, glass wool strip, centrifugal glass wool, glass wool belongs to a category of glass fiber, 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. Glass wool has good effect. 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, and glass wool. Cotton has good sound-absorbing properties, glass wool is corrosion-resistant, and glass wool has stable chemical properties. The main components of mineral wool stone are blast furnace slag, phosphate slag, fly ash, etc. Centrifugal glass wool 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. Centrifugal glass wool has good sound-absorbing properties. Centrifugal glass wool can be made into wall panels, centrifugal glass wool can be made into ceilings, centrifugal glass wool space sound absorbers, etc. It can absorb a large amount of sound energy in the room, reduce reverberation time, and reduce indoor noise. The sound absorption characteristics of centrifugal glass wool are not only related to thickness and bulk density, but also related to factors such as covering material and structural structure. The application of centrifugal glass wool in construction also needs to take into account many aspects such as cost, appearance, fire protection, moisture resistance, dust, aging resistance and other issues. Centrifugal glass wool is a porous sound-absorbing material with 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. Centrifugal glass wool has good sound absorption performance for medium and high frequencies. The main factors affecting the sound absorption performance of centrifugal glass wool are thickness, density and air flow resistance. Centrifugal glass wool density is the weight of material per cubic meter. Air flow resistance is the ratio of air pressure and air flow velocity on both sides of the material per unit thickness. Air flow resistance is the most important factor affecting the sound absorption performance of centrifugal glass wool. 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, sometimes plastic films are used in the municipalities of Beijing, Chongqing, Shanghai, Tianjin, Jiangsu Province, Yangzhou, Nanjing, Xuzhou, Lianyungang, Suqian, Huai'an, Yancheng, Taizhou, Nantong, Zhenjiang, Changzhou, Wuxi, Suzhou.
