Glass wool

Performance: the glass wool with unit weight is light, small coefficient of thermal conductivity, absorption coefficient, good flame retardant performance. Can be widely used in thermal equipment, air conditioning temperature, cold and heat pipe, cold storage preservation and the structure of the heat preservation, heat insulation, sound insulation, etc.

Centrifugal glass wool in the construction and utilization, the surface is likely to be additional has a role in perforated finishes, such as less than 0.5 mm of plastic film, metal wire mesh, window screening, fire prevention cloth, glass fiber cloth, etc., basic can keep the original sound absorption characteristics. Centrifugal glass wool has fine properties, such as fire prevention, heat preservation, easy cutting is one of the most commonly used material building sound absorption. But because of lack of decorative centrifugal glass wool surface, and there will be diffused fiber, must therefore be made into all kinds of hidden acoustic components used. The most commonly used is the cheapest cost structure is made within perforated plasterboard condole top or fill in the hole wall surface of centrifugal glass wool, perforation rate greater than *0%, basic can fully exert the sound absorption performance of the centrifugal glass wool. In order to prevent glass cotton fiber has been spilled,

Glass wool board after processing can be made into sound-absorbing ceiling board or sound-absorbing panels. General common glass wool board, *****0 kg/m3 around after glue curing treatment outsourcing fire formation acoustic fabric is not only beautiful and easy installation of sound-absorbing panels, common size 1.2 m * 1.2 m, 1.2 m * 0.6 m, 0.6 m * 0.6 m, the thickness of 2.5 cm or 5 cm. And there have been **0 kg/m3 painted directly on the surface of the glass wool acoustic decoration material sound-absorbing ceiling board. Whether the glass wool sound-absorbing panels or acoustic ceiling board, you need to use high bulk density of glass wool, and through certain reinforcement processing, in order to prevent the deformation of sheet or too loose. This kind of building materials has both good decorative and keep the good sound absorption characteristics of centrifugal glass wool, noise reduction coefficient of the NRC generally can reach more than 0.*5.

Within the stadium, workshop and other large space, in order to acoustic noise reduction, is often used in centrifugal glass wool as the main absorption body of sound-absorbing material. Sound absorbing body can be made according to the requirement plate, cylindrical, cone, or other isoforms. Internal filling centrifugal glass wool, absorption body surface using acoustic surface parcel. Because there are multiple surface acoustic absorption body, absorption efficiency is very high.

In road noise barriers, in order to prevent noise reflection, need for vehicle side absorption measures, often using centrifugal glass wool as filling material, the surface barrier board for perforated metal sheet. In order to prevent the glass wool in outdoor water be affected with damp be affected with damp, sometimes use PVC or plastic film package
