ã€China Aluminum Network】 Glass wool is made of centrifugal glass wool felt using Owens Corning (abbreviated as OC) unique patented centrifugal technology, glass wool will be molten glass fiber and thermosetting resin-based environmental protection formula bonding The agent processed product is an elastic felt body made of glass fiber with a diameter of only a few micrometers, and can be selected on-line for different moisture-proof veneers according to the use requirements. It has a lot of tiny air pores, which makes it play a role in thermal insulation, sound absorption, noise reduction, and security protection. It is a better material for thermal insulation, sound absorption and noise reduction of steel structures.
Glass wool belongs to a class of glass fibers and is an artificial inorganic fiber. Quartz sand, limestone, dolomite and other natural ores are used as the main raw materials, and some soda ash, borax and other chemical raw materials are melted into glass. In the melted state, the fluffy fine fibers are blown by an external force, and the fibers and fibers are three-dimensionally intertwined and intertwined with each other, exhibiting many fine gaps. This gap can be seen as a pore. Therefore, glass wool can be regarded as a porous material, with good thermal insulation and sound absorption properties.
Flame retardant, non-toxic, corrosion-resistant, small bulk density, low thermal conductivity, chemical stability, low moisture absorption, good hydrophobicity and many other advantages, is currently recognized as a superior performance of insulation, thermal insulation, sound-absorbing materials, with Very extensive use. The boards, felts and tubes made of this material have been widely used for thermal insulation, sound absorption and noise reduction in the fields of construction, chemical engineering, electronics, electric power, metallurgy, energy, transportation, etc. The effect is very significant.
Due to its soft texture and fine fibers, the centrifugal glass wool does not irritate the skin during construction and is therefore popular among construction companies and has become a preferred product for thermal insulation. When glass wool felt and sound-absorbing cotton felt are used as sound-absorbing materials, air layers or surface decorative materials are left behind. In the air layer thickness range of 100-150mm, the thicker the air layer, the higher the sound absorption rate in the middle and low-pitched areas. If the air is thickened to 300mm, the effective sound-absorbing rate is expanded to 100Hz.
Centrifugal glass wool board is made of centrifugal glass wool after curing, has a certain strength of the plate products, both in high temperature or low temperature environment can maintain good sound insulation and sound absorption performance, mainly used in high-rise building interior wall compartment , Ceiling ceilings, insulation in tin ducts or bellows, acoustic noise reduction in studios, computer rooms, etc. The surface can be pasted with PVC film fabrics, but also with aluminum foil. With light capacity, large sound absorption coefficient, flame retardant, and excellent chemical stability.
Centrifugal glass wool fluffy in the internal fibers, there are a lot of tiny pores, is a typical porous sound-absorbing material, with good sound absorption properties. Centrifugal glass wool can be made into wall panels, ceilings, space acoustic absorbers, etc., can absorb a large number of acoustic energy in the room, reduce reverberation time and reduce indoor noise.
