Fiberglass Packing Excellent Performance

Glass fiber is an excellent performance of inorganic non-metallic materials, Fiberglass Packing a wide range, the advantages of good insulation, heat resistance, Fiberglass Packing good corrosion resistance, high mechanical strength, but the brittle, wear resistance to be improved. It is made of glass ball or waste glass as raw material by high temperature melting, drawing, yarn, weaving and other processes made of its monofilament diameter of a few microns to twenty microns, the equivalent of a hair Of the 1/20 ~ 1/5, each bundle of fiber raw silk by hundreds or even thousands of monofilament composition. Glass fiber is usually used as a composite material in the reinforced materials, electrical insulation materials and insulation materials, circuit boards and other areas of the national economy. Fiberglass Packing Its main components are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc., according to the amount of alkali in the glass, can be divided into alkali-free glass fiber, alkali glass fiber and high alkali glass fiber.

Glass fiber than organic fiber temperature is high, non-combustible, Fiberglass Packing anti-corrosion, heat insulation, good sound insulation, high tensile strength, good electrical insulation. These features make the use of glass fiber far more widely than other types of fiber, the development speed is also far ahead. Glass fiber according to the shape and length, can be divided into continuous fiber, fixed fiber and glass wool; Fiberglass Packing according to the glass composition, can be divided into alkali, chemical resistance, high alkali, alkali, high strength, high elastic modulus and alkali ( Alkali-resistant) glass fiber. The main raw materials for the production of glass fiber are: quartz sand, alumina and pyrophyllite, limestone, dolomite, boric acid, soda ash, mirabilite, Fiberglass Packing fluorite and so on.

There are two kinds of glass fiber production process: two molding - crucible drawing method, a molding - pool rolling method. Crucible drawing process a wide range of glass raw materials at high temperature into a glass ball, and then the second glass ball melting, Fiberglass Packing high-speed drawing made of glass fiber precursor. Fiberglass Packing This process has high energy consumption, molding process instability, low labor productivity and other drawbacks, basically a large glass fiber manufacturers eliminated. Pool kiln drawing method to pyrophyllite and other raw materials in the furnace melting into a glass solution, remove the bubbles after the passage through the transport to the porous hole, high-speed drawing into glass fiber. Fiberglass Packing Kiln can be connected through a number of access to hundreds of leaks at the same time production. Fiberglass Packing This process is simple, energy saving, Fiberglass Packing forming stability, high efficiency and high yield, easy to large-scale fully automated production, become the international mainstream production technology, with the production of glass fiber production accounts for more than 90% of global production.
