fiberglass profiles Material classification

Glass fiber is an excellent performance of inorganic non-metallic materials, a wide range, the advantages of good insulation, heat resistance, good corrosion resistance, high mechanical strength, but the disadvantage is brittle, poor wear resistance. 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.

Introduce the material classification of the product, as follows:

Glass fiber according to the shape and length, can be divided into continuous fiber, fixed 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 ( Anti-alkali) glass fiber and so on.

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. Foreign glass fiber production capacity has reached 3 million tons, the actual production of 2.5 million tons, of which the pulp kiln production accounted for 85 to 90 percent of total output. In the total output of 2.5 million tons, for the enhancement of thermosetting plastic products about 100 million tons, for the thermoplastic products 700,000 tons. Glass fiber textile yarn and woven fabrics, knitted fabrics, mesh fabrics, stitched fabrics and multi-axial fabrics, fiberglass products factory is the largest variety of specifications of a class of glass fiber products, the development of fast, broad market prospects.
