Sales Telephone 3 Manager Wang 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. 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. Decoration and chemical properties are stable. When centrifugal glass wool felt and sound-absorbing cotton felt are used as sound-absorbing materials, an air layer is left behind or decorative materials are pasted on the surface. Within the range of - in the thickness of the air layer, the thicker the air layer, the higher the sound absorption rate in the mid- and low-range ranges. If the air is thickened to 3, the effective sound absorption rate range expands to . Wall sound absorption, wall sound insulation, wall insulation, and wall heat insulation. Glass wool felt is a rolled material made to meet the needs of large-area laying. In addition to maintaining the characteristics of thermal insulation, it also has excellent shock absorption and sound absorption properties, especially for medium and low frequencies and various vibration noises. Good absorption effect helps reduce noise pollution and improve the working environment. Glass wool felt with aluminum foil veneer also has strong heat radiation resistance and is an excellent lining material for high-temperature workshops, control rooms, machine room inner walls, partitions and flat roofs. Purpose: Glass wool felt and sound-absorbing cotton felt are ideal sound-absorbing and heat-insulating materials. They are widely used in noise-reducing sound cabinets for house walls, ship engine room insulation, computer rooms, refrigerators, various generator rooms, and pump rooms with constant temperatures. , audio adjustment, etc. Function: wall sound absorption, wall sound insulation, wall insulation, wall product use: Function: wall sound absorption, wall sound insulation, wall insulation, wall insulation The internal fibers of centrifugal glass wool are fluffy and intertwined, and there are a large number of tiny pores , is a typical porous sound-absorbing material with 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. 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. In construction applications, it is also necessary to take into account many aspects such as cost, aesthetics, fire protection, moisture resistance, dust, and aging resistance. 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. Sales call manager 3.
