???? Centrifugal glass fiber cotton, another name: glass wool, centrifugation, cotton, cotton fiber, cotton insulation, silencers cotton, fire cotton, cotton insulation, cotton insulation, acupuncture cotton, fire cotton, laminated cotton, etc., because centrifugal fiberglass versatile, low cost, simple construction, good effect and other reasons, making the centrifugal glass fiber cotton is one of the necessary materials for construction, with more and more advanced modern technology for noise. Energy, environmental protection and energy saving requirements are also increasing, which makes centrifugal fiberglass prospects for the future. Glass wool in the molten state centrifugal blowing glass coating technology of fibrosis filamentary materials made of a thermosetting resin, and then through the heat curing deep processing, can be made a series of products with a variety of purposes. It has a flame retardant, non-toxic, corrosion resistance, bulk density, low thermal conductivity, chemical stability, low moisture absorption, good hydrophobicity and many other advantages, is now recognized as the most superior performance insulation, heat insulation, sound-absorbing materials, has a very wide range of uses. Use the materials board, felt, pipe have been widely used in construction, chemical, electronics, electric power, metallurgy, energy, transportation and other areas of thermal insulation, sound absorption, the effect is very significant. Glass wool board, acoustic foam panels are an ideal acoustic and thermal insulation materials are widely used in house walls, ship engine room insulation; computer rooms, cold storage temperature; various generator room, pump noise reduction; stereo cabinets, audio adjustment. Role: wall sound-absorbing materials, wall insulation materials, wall insulation, wall insulation materials; centrifugal glass wool sound absorption characteristic not only with the thickness and density, but also with overlay materials, structures and other factors. In architectural applications needed taking into account the cost, aesthetics, fire, moisture, dust, anti-aging, and many other issues. Centrifugal glass wool is a porous sound-absorbing material, has good acoustic properties. Centrifugal glass wool sound absorption is not due to surface roughness, but because a large number of tiny pores communicating outside and holes. When sound waves incident on the glass wool, the acoustic energy into the material along the inside pores, voids caused by the vibration of the air molecules. Viscous drag of the air and the air molecules and the pore wall friction, acoustic energy is converted to heat loss. Centrifugal glass wool has good high-frequency sound absorption properties. Centrifugal glass wool impact absorption performance of the main factors of thickness, density and air flow resistance and so on. Density is the weight of material per cubic meter. Air flow resistance per unit thickness of material on both sides of the air pressure and air flow rate ratio. Centrifugal air flow resistance is the impact absorption properties of glass wool the most important factor. Flow resistance is too small, sparse explanatory material, easy to pass through the air vibration, acoustic performance degradation; flow resistance is too large, explanatory material dense, difficult to pass the air vibration, acoustic performance also declined. The centrifugal glass wool is concerned, there is an optimal acoustic performance flow resistance. There is a need centrifugal glass fiber cotton, another name: glass wool, centrifugation, cotton, cotton fiber, cotton insulation, silencers cotton, fire cotton, cotton insulation, cotton insulation, acupuncture cotton, fire cotton, laminated cotton customers go to Nanchang Chen tone Building Materials Co., buy centrifugal glass fiber cotton, another name: glass wool, centrifugation, cotton, cotton fiber, cotton insulation, silencers cotton, fire cotton, cotton insulation, cotton insulation, acupuncture cotton, fire cotton, laminated cotton, purchase hotline: 13755682031 , Xu.
