Glass fiber is an inorganic non-metallic material with excellent performance. It has the advantages of insulation, heat resistance, good corrosion resistance, and high mechanical strength. It is usually used as a reinforcing material, electrical insulation material and heat insulation material in composite materials. There are many types of glass fibers.
The glass fiber casing is made by weaving the non-alkali glass fiber yarn into the casing, then after high temperature treatment, coated with silicone resin and silicone rubber, it has all the characteristics of glass fiber. Because of the different ingredients, its application and performance are also different. So how to correctly distinguish various glass fibers?
According to the shape and length of glass fiber, it can be divided into continuous fiber, fixed-length fiber and glass wool; according to glass composition, it can be divided into non-alkali, chemical resistance, high alkali, medium alkali, high strength, high elastic modulus and alkali resistant glass Fiber etc.
The glass used in the production of glass fibers is different from other glass products. The internationally commercialized glass components for fibers include: e-glass, c-glass, high-strength glass fiber, ar glass fiber, a glass, e-cr glass, d glass.
The main raw materials for glass fiber production are: quartz sand, alumina and pyrophyllite, limestone, dolomite, boric acid, soda ash, mirabilite, fluorite ground glass fiber, etc. The glass fiber can be processed into various forms of products, such as yarn, untwisted roving, board, tube, etc. The infinitely long fiber drawn by the mechanical drawing method through the platinum alloy plate is called continuous glass fiber, commonly known as long fiber.
In addition to the above glass fiber components, a new type of alkali-free glass fiber has emerged in recent years. It does not contain boron, thereby reducing environmental pollution, but its electrical insulation and mechanical properties are similar to traditional e-glass.
Faced with a wide range of glass fibers, how to choose the materials that are suitable for them is of vital importance, and it also requires skill. This requires consumers to keep their eyes open when purchasing.
