Glass wool is used in a molten state centrifugal blowing spray technology for fibrosis filamentous material thermosetting resin, after thermal curing deep processing, products can be made with a variety of uses. It has a flame-retardant, non-toxic, corrosion resistance, bulk density of small, low thermal conductivity, chemical stability, low moisture absorption, good hydrophobic properties and many other advantages, is widely recognized as the most superior performance of thermal insulation, sound-absorbing material , with a very wide range of uses. Insulation board with this material, carpets, have been widely used in construction, chemical, electronics, electricity, metallurgy, energy, transportation and other areas, sound absorption, the effect is very significant. Due to centrifugal glass wool is soft, fine fiber construction will not irritate the skin, and thus by construction unit welcomed as a major raw material insulation, sound absorption preferred products using quartz sand, limestone, dolomite and other natural ore , with some soda, borax and other chemicals into the glass melt. In the molten state, with standard external blows thrown into flocculent fine fibers, for interchange between the fiber and the fiber, intertwined with each other, showing many of the small gap. This gap can be regarded as void. Thus, the glass wool can be regarded as a porous material, with excellent thermal insulation, sound absorption performance. Glass wool is molten glass fibrosis, cotton-like material, the chemical composition of metallic glass class, is an inorganic fibers having good shape, small size, density, thermal conductivity go to and fro, thermal insulation, good sound-absorbing properties, corrosion-resistant ornaments, chemical stability
