Glass wool belongs to a category of glass fiber, is a kind of artificial inorganic fiber. Glass wool is molten glass fibrosis, cotton like material, chemical composition of glass, is a kind of inorganic fiber. Glass wool has the characteristics of good molding, low volume density, thermal conductivity, thermal insulation, good sound-absorbing performance, corrosion resistance, and stable performance.
Glass wool using quartz sand, limestone, dolomite and other natural ores as the main raw materials, with some soda, borax and other chemical materials fused into glass. In the melting state, with the help of external blowing type cast into flocculent fine fiber, fiber and fiber for three-dimensional cross, intertwined together, showing a lot of small gaps. Such gaps can be regarded as pores. Therefore, glass wool can be regarded as a porous material with good thermal insulation and sound absorption properties.
Centrifugal glass wool felt is one kind of glass wool products, the molten glass fibrosis and thermosetting resins is given priority to the formula of binder for processed goods, is composed of only a few microns diameter produced by glass fiber blanket of elastic body, and can choose according to the requirement of different moistureproof cover online composite. Glass wool has a large number of tiny air pores, so that it plays a role in heat insulation, sound absorption and noise reduction.
Centrifugal glass wool has many advantages, such as flame retardant, non-toxic, corrosion resistance, small bulk density, low thermal conductivity, strong chemical stability, low moisture absorption rate, good hydrophobicity and so on. It is recognized by many users as a thermal insulation, heat insulation and sound-absorbing material with superior performance. Centrifugal glass wool is widely used. Centrifugal glass wool can also make new glass plate, centrifugal glass wool felt, centrifugal glass wool tube and other materials and these materials are also widely used in construction, chemical industry, electronics, electric power, metallurgy, energy, transportation and many other fields. Sound absorption, noise reduction, thermal insulation effect is very significant.
