Product Description


Centrifugal Glass Wool Felt

Product introduction:

Yu Ou Nuo Centrifugal Glass Wool is a filamentary material made of molten glass by centrifugal blowing process to fiberize and spray thermosetting resin, and then through thermal curing and deep processing, it can be made into a series of products with multiple uses. Centrifugal glass wool has fluffy and intertwined fibers with a large number of tiny pores. Centrifugal glass wool has fluffy and intertwined fibers with a large number of tiny pores. Centrifugal glass wool can be made into wallboard, ceiling, space absorber, etc., which can absorb a lot of sound energy in the room, decrease reverberation time and reduce indoor noise.

Centrifugal Glass Wool Felt

It has many advantages, such as flame retardant, non-toxic, corrosion-resistant, small volume-weight, low thermal conductivity, strong chemical stability, low moisture absorption rate, good hydrophobicity and so on. It is recognized as the most superior thermal insulation and sound-absorbing material with a wide range of applications. The Centrifugal Glass Wool Insulation Board, Centrifugal Glass Wool Felt and Centrifugal Glass Wool Pipe made of this material have been widely used in thermal insulation and noise reduction in the fields of construction, chemical industry, electronics, electric power, metallurgy, energy, transportation, etc.

Because centrifugal glass wool has soft texture and fine fibers, it will not irritate the skin during construction, so it is popular with construction units and becomes the first choice for thermal insulation.

[Advantages] flame retardant, non-toxic and corrosion resistant.

[Application] centrifugal glass wool board, centrifugal glass wool felt.

[Features] no skin irritation during construction。

[Thickness] 100-150mm

[Function] wall sound absorption, wall heat insulation

Centrifugal glass wool felt is a roll material made to meet the needs of large-area laying. In addition to maintaining the characteristics of thermal insulation, it also has excellent shock absorption and sound absorption characteristics, especially for low frequency and various vibration noises. It has a good absorption effect, which is conducive to reducing noise pollution and improving the working environment.

This material can be arbitrarily cut according to needs during construction, and is mainly used for shock absorption, sound absorption, and noise reduction treatments in building interiors, muffler systems, vehicles, refrigeration equipment, and household appliances, with ideal effects.

Glass wool felt with aluminum foil veneer also has strong heat radiation resistance. It is an excellent lining material for high-temperature workshops, control rooms, machine room internal walls, compartments and flat roofs.

The influence factors of centrifugal glass wool are as follows:

Yu Ou Nuo centrifugal glass wool has good sound absorption performance for medium and high frequency sound. The main factors affecting the sound absorption performance of centrifugal glass wool are thickness, density and air flow resistance. Density is the weight per cubic meter of material. Air flow resistance is the ratio of air pressure and air velocity on both sides of material per unit thickness. Air flow resistance is the most important factor affecting the sound absorption performance of centrifugal glass wool. If the flow resistance is too small, it means that the material is sparse, the air vibration is easy to pass through, and the sound absorption performance decreases; if the flow resistance is too large, it means that the material is dense, the air vibration is difficult to pass in, and the sound absorption performance also decreases. For centrifugal glass wool, the sound absorption performance has the best flow resistance.

The sound absorption performance of yuono centrifugal glass wool is also closely related to the installation conditions. When there is air layer behind the glass wool board, the sound absorption effect is similar to that of the glass wool board without air layer of the same thickness. In particular, the sound absorption performance of the medium and low frequencies will be greatly improved than that of the material pasted on the hard bottom, and the sound absorption coefficient will increase with the increase of the thickness of the air layer, but the effect is not obvious when it increases to a certain value.

The glass wool with different bulk density is stacked together to form a form with a gradually increasing volume weight, which can obtain a greater sound absorption effect. For example, stacking a 2.5cm thick 24kg/m3 cotton board with a 2.5cm thick 32kg/m3 cotton board will have better sound absorption than a 5cm thick 32kg/m3 cotton board. The 24kg/m3 glass wool board is made into a 1m long wedge with a triangular cross section. The surface density of the material gradually increases, and the average sound absorption coefficient can be close to 1.
