Answer:

Glass wool is categorized into glass fiber, which is a manmade inorganic fiber. Glass wool employs quartz sand, limestone, dolomite and other natural ores as the main raw materials, accompanying with some soda ash, boraxes and other chemicals to melt into glass. In the molten state, cotton-shaped thin fiber can be made by means of blowing force, and fibers and fibers will be vertically crossed and intertwined with each other.
Quartz wool / glass wool / insulated cotton [Instrument]. Products introduction: quartz wool: it is used as the filler of analytical instruments or small reaction tubes in laboratory, or as the insulation material. Temperature resistance: about 1300 degrees. Specifications: 1 to 3um and 3 to 5um. Packaging:
It belongs to quartz fiber. Quartz fiber is a cotton-shaped fiber made up of high purity silicon dioxide and natural quartz crystal. Its purity is 99.95% purity and density is 2.2g / cm3. The tensile strength is 7GPa and the tensile modulus is 70GPa. It has heat resistance, corrosion resistance and softness. At high temperatures, it remains high retention rate, stable dimension, good thermal shock resistance, chemical stability, transparency and electrical insulation. Filament with a diameter of 4 to 10μm can be used for reinforcing. Fiber?diameter of quartz wool depends on use, which in general is about 0.7 to 10μm. Manufacturing methods: (1) Drawing with melting quartz rod or pipe oxy-hydrogen flame, and then jetting it with oxy-hydrogen flame blowpipe to make into quartz wool with a diameter of 0.7 to 1 μ m; (2) Quartz is made into short fibers and the mats with high speed airflow before being melted with flame; (3) Making quartz fibers or rods go through oxy-hydrogen flame or coal gas flame at a constant velocity for the sake of softening them and then drawing them into filaments at a high speed. It is mainly used as the reinforcement of electrical insulating materials, thermal insulating materials and composite materials. It serves as the radome of aircraft nose, the exhaust nozzle of rockets, ablative materials of spacecraft and thermal insulation materials and so on. Glass wool is categorized into glass fiber, which is a manmade inorganic fiber. Glass wool is a material which fibering melting glass to form cottony shape. Its chemical composition belongs to the classification of glass, being an inorganic fiber. So, it is good shaped with small volume density, low thermal conductivity, good thermal insulation and sound absorption properties, great corrosion resistance as well as stable chemical performance.
Hello! I'm glad to answer your question! Glass wool is made by natural minerals such as quartz, dolomite, feldspar, limestone coupled with soda ash, borax and other auxiliary materials ... Glass wool is a fine fibrous material through drawing, blowing or swing of external force in melting state. Glass wool is an inorganic fiber. It has the following basic characteristics: ① It has good thermal insulation property at high and low temperatures. ② It is noncombustible without producing harmful gases, so it is designated as "legal non-combustible material" by various countries. ③ It has uniformly elastic restoring force. ④ Its moisture absorption rate is small under humid conditions. ⑤ Its coefficient of linear expansion is small. ⑥ It has low aging rate, able to remain the original performance after long-term use. ⑦ It has good machinability. Asbestos product is produced through the process that thining slate fibers by chemical beam to make them become slurry structure, and then sizing it at high temperatures. This product is characterized by lowest aging, non-degenerating, poisonless and tasteless, light weight and low thermal conductivity, etc. In addition, it is easy to construction, able to be cut freely and packaged based on types without irritating skin and wear and tear in construction and other advantages. Hope it will help you.
