Centrifugal glass wool felt Products :

Centrifugal glass wool felt is laid membrane to adapt to the needs of a large area made , in addition to maintaining the characteristics of thermal insulation , but also has very excellent shock absorption. Sound absorption characteristics. Especially for the low-frequency noise and vibration are a variety of good absorption effect , helps to reduce noise pollution , improve the working environment in the construction of this material can also be arbitrarily cut, mainly for the building interior , muffler systems, transport , refrigeration equipment, household appliances damping , sound absorption, noise reduction, achieved very good results . There are glass wool carpets foil surface , but also has a strong thermal radiation, high temperature workshops, control room wall, and the flat top compartment lining material .

Centrifugal glass wool felt Usage:

Centrifugal glass wool felt , sound-absorbing cotton blanket is an ideal acoustic and thermal insulation materials are widely used in house walls, ship engine room insulation ; various generator room, pump room noise reduction ; computer room , freezer thermostat ; stereo cabinets , audio adjustment.

Centrifugal glass wool felt sound absorption coefficient :

Glass wool carpets, sound-absorbing cotton blankets for sound-absorbing materials used, keep in the back surface air layer or paste decorative materials. The thickness of the air layer within the range of 100-150mm , the thicker layer of air , the higher the sound absorbing rate of the low range , such as air thickened to 300mm, the effective range of the sound absorption rate extended to 100Hz. Sound-absorbing walls , wall insulation, wall insulation , wall insulation .

Centrifugal glass wool felt fluffy fiber staggered inside , there are a lot of tiny pores, is typical of porous sound-absorbing material, has good acoustic properties. Centrifugal glass wool can be made into wall , ceiling, space absorber , etc. , can be a lot to absorb sound energy in the room , reducing reverberation time, reduce interior noise . Sound absorption characteristics of centrifugal glass wool felt not only with the thickness and density , but also on the factors overlay material , structure and so on. In architectural applications need while taking into account cost, aesthetics, fire, moisture , dust, anti-aging , and many other problems.
