Pultruded Fiberglass Excellent performance

Pultruded 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. Pultruded 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.

Pultruded glass fiber company to introduce the product classification of materials, as follows:

Pultruded 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 resistance Alkali (alkali) pultruded glass fiber.

Production of pultruded glass fiber main raw materials 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 pultruded glass fiber, commonly known as long fiber. Non-continuous fibers made by rollers or air streams are called fixed-length pultruded glass fibers, commonly referred to as short fibers.

Pultruded glass fibers are divided into different grades by composition, nature and purpose. According to the standard level, E-class pultruded glass fiber use the most common, widely used in electrical insulation materials; S grade for the special fiber. Pultruded glass fiber itself has a series of excellent characteristics, with the development and improvement of modern technology, but also pultruded glass fiber for a number of modified and composite, so that it has more, better, more full of features, glass Fiber has become the national economy in the industrial sector irreplaceable new functional materials and structural materials, pultrusion glass fiber plant will have unlimited broad prospects for development.

Foreign pultruded 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. Pultruded glass fiber textile yarn and woven fabrics, knitted fabrics, mesh fabrics, stitched fabrics and multi-axial fabrics, pultruded glass fiber products factory in a variety of specifications of a class of fiberglass products, the development of fast, the market Broad prospects.
