Glass wool board wall Glass wool board outside wall Glass wool board low density Glass cotton plate Glass, Glass wool, cotton board is a centrifugal Glass fibre, after curing processing are made of a certain intensity plank product, no matter in low or high temperatures environment all can keep good thermal insulation, sound-absorbing performance is mainly used for senior architectural interior compartment, smallpox condole supports, hut duct or bellows inside the heat preservation, studio, computer room interior noise of sound absorption, has wide application prospects. The glass fiber glass cotton belong to one category, is a kind of man-made inorganic fibers. Using quartz sand, limestone, dolomite and other natural mineral as the main raw material, cooperate with some soda, borax etc chemical raw materials melting into glass. The melting condition, with the aid of the external force blow shape.whether jilt into floe fine fiber, fiber and fiber for interchanges between, intertwining together, presents many small gap. The gap can be regarded as porosity. Therefore, glass cotton can be regarded as porous materials, good insulation, sound-absorbing performance. Glass wool is will molten glass fibrosis, forming cotton shape material, chemical composition of glass class, it is a kind of inorganic qualitative fiber. Have shape, small volume density, good thermal conductivity 彽, insulation insulation, sound-absorbing performance is good, decay resistance act the role ofing, stable in chemical. Glass cotton is the glass molten state law centrifugal injection process fiber forming and spraying thermosetting resin made after filamentous material, then after thermal curing deep processing and manufactured. Glass cotton have fire prevention, antivirus, corrosion resistance, light quality, high temperature resistant, long service life, moistureproof sex and hydrophobic good, and many other advantages. Glass cotton is recognized superior heat preservation and heat insulation, sound-absorbing materials. Color glass cotton has been widely used in construction, chemical, electronic, metallurgy, energy, transportation and other areas of insulation and sound absorption and noise reduction engineering effect is significantly. According to user's specific needs, our company can manufacture various color glass cotton. Belong to one of the categories, glass fiber is a kind of man-made inorganic fibers. Using quartz sand, limestone, dolomite and other natural mineral as the main raw material, cooperate with some soda, borax etc chemical raw materials melting into glass. The melting condition, with the aid of the external force blow shape.whether jilt into floe fine fiber, fiber and fiber for interchanges between, intertwining together, presents many small gap. The gap can be regarded as porosity. Therefore, glass cotton can be regarded as porous materials, good insulation, sound-absorbing performance. The internal structure of centrifugal glass cotton internal fiber fleeciness crisscross, there are lots of tiny pore, is a typical porous sound-absorbing material, it has good sound-absorption properties. Centrifugal glass cotton can be made into wallboard, ceiling, space sound-absorbing body etc, can absorb in a large amount, reduce the room doubled the reverberation time, reduce indoor noise. Characteristics of centrifugal glass wool sound-absorbing properties not only and thickness and density of related, also with cover face materials, structural factors. In architectural applications still need to juggle cost, beautiful, fire prevention, moisture-proof, dust, ageing resistance aspects of problems. Centrifugal glass cotton belongs to the porous sound-absorbing material, have good sound-absorbing performance. Centrifugal glass cotton can sound-absorbing reason is not due to rough surface, but because a large number of internal and external connected tiny pore and holes. When sound waves transmits centrifugal glass cotton, sound waves can follow pore into material interior, cause voids air molecules vibration. Due to the air of viscous resistance and air molecules and pore wall friction, sound energy into heat energy losses. Centrifugal glass cotton for sound hf have better sound-absorbing performance. Influence centrifugal glass wool sound-absorbing properties of main factor is the thickness and density and air flow resistance etc. Density is every stere materials of weight. Air flow resistance is the unit thickness materials on both sides of the air pressure and velocity of air ratios. Air flow resistance is the effect of centrifugal glass wool sound-absorbing performance is the most important factor. Flow resistance is too small, explanatory material sparse, air vibration easily through, sound-absorbing performance drop; Flow resistance is too big, explanatory material close-grained, air vibration is difficult to pass into, sound-absorbing performance also declined. For centrifugal glass cotton speaking, sound-absorbing properties exist optimum flow resistance. In practical engineering, the determination of air flow resistance is difficult, but can be by thickness and density of roughly and control. 1, along with the increase in thickness, low frequency sound absorption coefficient noticeably increased, but the high-frequency little change （high frequency absorption always larger）. 2, thickness is changeless, bulk density increases, in low frequency sound absorption coefficient also increased, But when density increases to certain degree, materials become close-grained, flow resistance than optimal flow resistance, and the absorption coefficient instead decline. For thickness exceed 5cm bulk density for 16Kg/m3 centrifugal glass cotton, the low frequency 125Hz about 0.2, hf （> 500Hz） the absorption coefficient has been close to 1. When thickness from 5cm continue to increase, the low frequency sound absorption coefficient of the gradually enhance, when thicker than 1-m above, the low frequency sound absorption coefficient of the 125Hz will close to 1. When thickness is changeless, bulk density increases, the centrifugal glass cotton of low-frequency absorption coefficient and it will continue to increase, when the density of close to 110kg/m3 when sound-absorbing performance reach maximum thickness, frequency, 50 125Hz place close to 0.6-0.7. Density is beyond 120kg/m3, the sound absorption performance drop, because materials instead become dense, hf sound-absorbing performance greatly affected, when density is beyond 300kg/m3, the sound absorption performance decreased a lot. Architectural acoustics commonly used in the thickness of the glass wool sound-absorbing has 2.5 cm, 5cm, bulk 10cm, 16, 24 and 32, 48, 80, 96, 112kg/m3. Usually use 5cm thick, 12-48kg/m3 centrifugal glass cotton. Centrifugal glass cotton the sound-absorbing performance with installation conditions have a close relationship. When the glass wool board behind it, there is air layer, with no air same thickness of glass wool board absorption effect similar. Especially in low frequency sound absorption performance than real posted on hard material underside proudct has increased greatly, and the absorption coefficient with the air layer thickness increases with the increased to certain value, but the effect is not obvious after. Use different density of glass cotton overlays and together, forming density increase gradually form, can gain greater absorption effect. For example, the layer of 2.5 cm thick 24kg/m3 cotton plate with a layer of 2.5 cm thick 32kg/m3 cotton board fold and together the absorption effect is better than a layer of 32kg/m3 5cm thick wool boards. Will 24kg/m3 glass wool board made 1-m long sections for triangular JianPi, material surface density increase gradually, average absorption coefficient can close to 1. Glass wool is with unique centrifugal technology, will molten glass fibrosis and performs thermosetting resin mainly of environmental protection formula binder and processed goods, be a kind by only a few microns in diameter of glass fiber, produced by the elastic fiberglass products, and can according to different customers' requirement choose moistureproof temps online compound. Because of its large tiny air gap, make its have insulation, sound-absorbing noise reduction and safety protection function, is building insulation, sound-absorbing drop the best materials. Experiences-can Unique advantages, unique technology, compression after packing resilient rate for 99.2%. Soft, thin glass fiber minimize construction produced in --.
