 Centrifugal glass fiber cotton

The glass fiber glass cotton belongs to a category, is a kind of artificial inorganic fibers. Using quartz sand, limestone, dolomite and other natural mineral as the main raw material, with some soda ash, borax etc chemical raw materials melting into glass. In the melting state, with the aid of the external force blow off the floe type into fine fiber, and fiber for the interchange between, intertwined with each other, presents many small gap. The gap can be regarded as the pore. Therefore, glass cotton can be thought of as a porous material, it has good heat insulation, sound absorption performance. Centrifugal glass fiber cotton is will molten glass fibrosis, form the shape of cotton material, chemical composition of glass class, is a kind of inorganic qualitative fiber. Have shape, small volume density, good thermal conductivity, heat preservation heat insulation, sound-absorbing performance is good, corrosion resistance act the role ofing, stable in chemical.

The major components of the stone mineral wool is blast furnace slag, phosphorus slag and fly ash, etc. Centrifugal glass cotton centrifugal glass cotton internal fiber fleeciness crisscross, there are lots of tiny pore, is a typical porous sound-absorbing materials, has a good sound absorption characteristics. Centrifugal glass cotton can be made into wall, ceiling, space absorption body, etc, can absorb a large room sound energy, reduce the reverberation time, reduce indoor noise. Centrifugal glass cotton absorption characteristics not only and thickness and density of relevant, and cover face materials, other factors, such as the construction of structure. In the building to be used for both the cost, beautiful, fire prevention, moistureproof, dust, ageing resistance and so on various problems. Centrifugal glass cotton belongs to the porous absorption material, have good sound absorption performance. Centrifugal glass cotton to the absorption of the reason is not because the surface is rough, but because of a large number of inside and outside of the small pore and holes connected. When sound waves to centrifugal glass cotton incident, sound waves can go down the material internal pore, causes the gaps in the vibration of air molecules. Because the air viscous resistance and air molecules and pore wall of friction, sound energy into heat energy and loss. Centrifugal glass cotton in the voice of high frequency have better sound-absorbing performance. Influence centrifugal glass wool acoustic performance is the main factor thickness, density and air flow resistance, etc. Density is the weight of material per cubic meter. The air flow resistance is the unit thickness materials on both sides of the air pressure and the ratio of the air velocity. The air flow resistance is the effect of centrifugal glass wool acoustic properties of the most important factors. Flow resistance is too small, explanatory material sparse, air vibration easy to go through, the sound absorption performance down; Flow resistance is too big, the material that is close-grained, air vibration is difficult to pass into, the sound absorption performance also decline. For centrifugal glass cotton speaking, the sound absorption performance there an optimal flow resistance. In the practical engineering, the determination of air flow resistance is difficult, but can be by thickness and density of a rough estimate and control. 1, with increasing the thickness, the low frequency sound absorption coefficient significantly increased, but the high frequency change little (high frequency absorption always larger). 2, the same thickness and density increases, the low frequency sound absorption coefficient also increase; But when density increases to certain degree, the material be reinforced, and flow resistance than the best flow resistance, and the absorption coefficient down instead. For thickness more than 5 cm bulk density for 16 Kg/m3 centrifugal glass cotton, the low frequency 125 Hz is about 0.2, the high frequency (> 500 Hz) the absorption coefficient has been close to 1. When thickness from 5 cm continue to increase, the low frequency sound absorption coefficient of the gradually improve, when more than 1 m above the thickness, the low frequency sound absorption coefficient of the 125 Hz will also close to 1. When the same thickness and density increases, the centrifugal glass cotton low frequency sound absorption coefficient and it will continue to increase, and when the density of close to 110 kg/m3 sound absorption performance when reach maximum, 50 mm thick, frequency 125 Hz place close to 0.6-0.7. Bulk density of more than 120 kg/m3, the sound absorption performance drop instead, because materials become density, high frequency of sound absorption performance was a great influence, when the density of more than 300 kg/m3, the sound absorption performance reduce a lot.

Architectural acoustics of commonly used sound-absorbing the thickness of the glass cotton is 2.5 cm, 5 cm, 10 cm, bulk density has 16, 24, 32, 48, 80, 96, 112 kg/m3. Usually use 5 cm thick, 12-48 kg/m3 centrifugal glass cotton. Centrifugal glass cotton sound absorption performance of the installation conditions and also have a close relationship. When the glass wool board behind it, there is air layer, and the same thickness of glass wool board without air layer absorption effect similar. Especially in low frequency sound absorption performance of materials in hard than stick on the underside increased greatly, and the absorption coefficient with the thickness of the air layer will increase with the increase, but the increase to a certain value the effect is not obvious after. Use different density glass cotton overlays and together, forming density increase gradually form, can gain greater absorption effect. Such as a layer of 2.5 cm thick 24 kg/m3 cotton board and a layer of 2.5 cm thick 32 kg/m3 cotton board fold together and absorption effect in better shape than a layer of 5 cm thick 32 kg/m3 cotton board. Will 24 kg/m3 glass cotton board makes 1 m long section for triangular JianPi, material surface density increase gradually, average absorption coefficient can close to 1.

Centrifugal glass cotton in building use, the surface often to additional have certain effect of the perforated surface decoration, such as less than 0.5 mm plastic film, metal network, screens, fire prevention cloth, spun glass cloth, basic can keep the original sound absorption characteristics. Centrifugal glass cotton has fire, heat preservation, easy to cutting and good characteristic, is building the absorption one of the most commonly used material. But because of centrifugal glass cotton surface does not have adornment sex, and will have fiber on, so we must make various kinds of sound absorption component concealment used. The most commonly used is the cheapest cost structure is perforated paper face plasterboard condole top or make it fills in centrifugal glass cotton perforation slab wall surface, perforation rate of more than 20%, the basic can completely to play out centrifugal glass cotton sound-absorbing properties. In order to prevent the cotton fiber glass spilled, need to be in with a layer of behind perforation plates non-woven, SangPiZhi etc perforated fabric, or the use of glass cloth, plastic film, glass cotton package. And perforation paper face plasterboard similar panel and perforation metal plate (such as aluminum plate), perforated board, perforated fiber floor slab, perforated mineral wool board, etc.

Glass wool board after treatment can be made into the absorption condole roof or absorption wallboard. General common will 80-120 kg/m3 glass wool board surrounding the glue solidified treatment outsourcing fire prevention perforated fabric form it is beautiful and easy installation of sound absorption wallboard, common size of 1.2 m x 1.2 m, 1.2 m x 0.6 m, 0.6 m x 0.6 m, thickness of 2.5 cm or 5 cm. Also in the 110 Kg/m3 glass cotton surface directly spray brush perforated adornment material form of sound absorption condole roof. Whether the glass wool acoustic panels or sound absorption board condole top, all need to use high density glass cotton, and after certain strengthen treatment, in order to prevent the sheet deformation or too loose. This kind of building materials with both good adornment sex and retained the centrifugal glass cotton good sound absorption characteristics, noise reduction coefficient NRC general can achieve more than 0.85.

In the stadium, and the workshop, and other large space inside, in order to the absorption noise reduction, often use with the centrifugal glass cotton as the main absorption material absorption of the body. The absorption body can be made according to the requirement, columnar plate, the cone, or other different body. The absorption body internal filling centrifugal glass cotton, the surface using perforated facing package. Because the absorption body have multiple surface absorption, and the absorption efficiency is very high. In road noise barriers, in order to prevent noise reflection, need to take in vehicle side absorption measures, also often use glass cotton as fill material centrifugal, the surface of the metal plate barrier for perforation plate. In order to prevent glass cotton in outdoor bibulous damp, sometimes use PVC or plastic film wrapping. Glass cotton and centrifugal glass cotton.
