What is the composition of Glass wool blanket for metal building roofing?
Glass wool blanket (a roll made to meet the needs of large-area laying) and the roll felt belongs to a category of Glass Fiber (Fiber) and is an artificial inorganic fiber. Natural materials such as quartz sand (properties: silicate minerals), limestone, dolomite, etc. are used as raw materials (Raw material), and some raw materials such as soda ash and boron (B) sand are melted into glass. In the melted state, the flocculent fine fibers are formed by the external force system, and the fibers and the fibers are three-dimensionally intersected and entangled with each other to present a plurality of fine gaps, which can be regarded as pores. Therefore, the glass wool felt can be regarded as a porous material, and has good heat insulation and sound absorption properties. A glass wool blanket stack of different bulk density is used to form a form in which the bulk density is gradually increased, and a larger sound absorbing effect can be obtained. For example, a 62.5px thick 24kg/m3 cotton board and a 62.5px thick 32kg/m3 cotton board are better than a 125px thick 32kg/m3 cotton board. The 24kg/m3 glass lap sheet is made into a triangular tip with a length of 1m, the material density increases gradually, and the average sound absorption coefficient can be close to 1.
Production technology (Technology)Of Glass wool blanket for metal building roofing : Glass wool felt is a unique technology that combines molten glass fiber with thermosetting resin (Thermosetting Resin). The processed product is a flexible glass fiber product made of glass fiber having a diameter of only a few micrometers, and can be used according to different requirements of customers (kè hù). Choose moisture-proof veneer online compound. Glass wool felt is a coil 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 medium and low frequency and various vibration and noise. It has a good absorption effect, which is beneficial to reduce noise pollution and improve the working environment. Because it has a large number of tiny air gaps, it plays the role of heat insulation (heat protection), sound absorption and noise reduction and safety protection. It is the best material for building thermal insulation and sound absorption and lowering (Material) ). Unique advantages, unique technology, the rebound rate after compression packaging is 99.2%.
