Glass wool insulation material is made of quartz sand, feldspar, sodium silicate, boric acid, etc. as the main raw materials. After high-temperature melting, the fiber is made into a cotton-like shape, and a thermosetting resin binder is added to pressurize and shape at high temperature to produce boards, felts, and pipe products of various shapes and specifications. Aluminum foil or film can also be pasted on its surface. This product has light bulk density, small thermal conductivity, large absorption coefficient and good flame retardant properties. It can be widely used in thermal equipment, air conditioning constant temperature, hot and cold pipes, oven drying rooms, refrigeration and preservation, and thermal insulation, heat insulation, and sound insulation of buildings.
Centrifugal glass wool
Glass wool is a filamentary material made by fiberizing glass in a molten state using a centrifugal blowing process and spraying thermosetting resin. It is then further processed by heat curing and can be made into a A series of products for various purposes. It has many advantages such as flame retardant, non-toxic, corrosion-resistant, small bulk density, low thermal conductivity, strong chemical stability, low moisture absorption, and good hydrophobicity.
Application:
Cotton Board
Centrifugal glass wool board is a board product with a certain strength made of centrifugal cotton after curing treatment. It can maintain good thermal insulation in high or low temperature environments. Thermal insulation performance is mainly used for interior wall partitions of high-end buildings, ceilings, iron ducts or air box inner wall insulation, sound absorption and noise reduction in computer rooms, sweat control in metal ceilings, etc. It has broad application prospects.
Cotton felt
Centrifugal 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 it has good absorption effect on medium and low frequency and various vibration noises, which is helpful to reduce noise pollution and improve the working environment.
This material can be cut as needed during construction. It is mainly used for shock absorption, sound absorption, and noise reduction in building interiors, silencer systems, vehicles, refrigeration equipment, and household appliances. The effect is very ideal.
Glass wool felt with aluminum foil veneer also has strong resistance to heat radiation and is an excellent lining material for high-temperature workshops, control rooms, machine room inner walls, partitions and flat roofs. []
When centrifugal glass wool is used in buildings, the surface is often attached with a certain sound-permeable finish, such as plastic film smaller than . sound absorption properties. Centrifugal glass wool has fine properties such as fire prevention, thermal insulation, easy for cutting, and is one of the most commonly used materials for building sound absorption. However, since the surface of centrifugal glass wool has no decorative properties and fibers are spilled, it must be made into various sound-absorbing components for concealed use. The most commonly used and low-cost structure is the suspended ceiling of perforated gypsum board or the wall of perforated board filled with centrifugal glass wool. When the perforation rate is greater than 1, the sound absorption performance of centrifugal glass wool can basically be fully exerted. In order to prevent glass wool fibers from spilling out, it is necessary to attach a layer of sound-transparent fabric such as non-woven fabric or mulberry paper behind the perforated plate, or wrap the glass wool with glass cloth, plastic film, etc. Panels similar to perforated plasterboard include perforated metal panels (such as aluminum panels), perforated wood boards, perforated fiber cement boards, perforated mineral wool boards, etc.
After treatment, glass wool boards can be made into sound-absorbing ceiling panels or sound-absorbing wall panels. 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, it is sometimes wrapped with or plastic film.
