Classification of glass fibers

Glass fiber according to the shape and length, can be divided into continuous fiber, fixed length fiber and glass wool; 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, fluorite and so on. The production method is divided into two categories: one is to make the molten glass directly into the fiber; one is made of molten glass first made of 20mm diameter glass ball or rod, and then in a variety of ways to heat remelting made after the diameter of 3 ~ 80μm very fine fibers. Through the platinum alloy plate by mechanical drawing method of drawing infinite fiber, called continuous glass fiber, commonly known as long fiber. Non-continuous fibers made by rollers or air streams are called fixed-length glass fibers, commonly referred to as short fibers.

Glass fiber according to the composition, nature and use, divided into different levels. According to the standard level (see table), E grade glass fiber use the most common, widely used in electrical insulation materials; S grade for special fibers.
