Centrifugal glass wool is silk-like material made by fiberizing melted glass and then coating with thermosetting resin through centrifugal blowing process. By means of thermal setting, this material can be further processed into series of products for multi-purpose uses, such as glass wool board, blanket, fiberglass air-conditioning duct, air-conditioning board, refractory glass wool and so on. it has numerous advantages such as noncombustible , nontoxic and resistant to corrosion , and low weight by volume , low thermal conductivity, stable chemical property, low moisture rate and good con good hydrophobicity. It is widely recognized as the heat-preservation, thermal insulation and sound absorption material with excellent performances. The board and blanket products made of this material have been used in heat preservation, thermal insulation and sound absorption in construction, chemical industry, electronic industry, electric power, metallurgy. energy industry and communication , presenting very good result .
Owing to glass wool good performances, e.g., thin and Iong inner fiber, low thermal conductivity, it can stop air flowing and heat transforming. meanwhile, it can quickly reduce the transportation of sound to make effects of insulation and sound-absorption. Centrifugal glass wool is divided into glass wool boards and blanket.
Glass wool board is processed by putting the thermosetting binder into the glass wool, by pressing and heating, and then, by curing. Then are widely used for insulation, ventilation and the adjustment of air-conditioner in commercial industry and residential constructions. Meanwhile, they have the effect of energy-saving insulation, sound-controlling and improving the indoor air quality.
It was the best material used for the insulation and sound absorption of steel structures. It mainly includes bare blanket and blanket with foil-clad covered. They are widely used in industrial plants, warehouses, public facilities, exhibition centers, shopping centers, cold stores and a variety of indoor playgrounds, sports grounds and other buildings.
Glass wool board can insulate, save energy and reduce the cost for the air-conditioner system. It has such excellent performance as sound-absorption, reducing construction load, fast process, shorten construction cycle, etc.
Refractory glass wool with light quality, durability and insulation performance is generally used in power station flue warm air duct and steam pipeline. It also used in the insulation for the pipe with the diameter exceeding 300mm and noise reduction for high temperature mediums such as boilers, reaction vessels ,shells of tank, piping etc. in power plant, chemical industry and pharmaceutical industry.
