GLASS FIBER PRODUCTS

　　 Glass fiber is a kind of inorganic non-metallic material with excellent performance. It has many types. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. It is pyrophyllite, quartz sand, limestone, dolomite, boron calcium The six kinds of ores such as stone and boehmite are made of raw materials through high-temperature melting, drawing, winding, weaving and other processes. The diameter of the monofilament is several microns to more than twenty microns, which is equivalent to a hair thread. 1/20-1/5 of each fiber bundle is composed of hundreds or even thousands of monofilaments. Glass fiber is usually used as a reinforcing material in composite materials, electrical insulation materials and thermal insulation materials, circuit substrates and other fields of the national economy.
　　 When glass fiber is used as a reinforcing material for reinforced plastics, the biggest feature is the high tensile strength. The tensile strength is 6.3～6.9 g/d in the standard state and 5.4～5.8 g/d in the wet state. Density 2.54g/cm3. Good heat resistance, no effect on strength when the temperature reaches 300℃. It has excellent electrical insulation and is a high-grade electrical insulation material. It is also used for thermal insulation materials and fire protection shielding materials. Generally only corroded by concentrated alkali, hydrofluoric acid and concentrated phosphoric acid.
　　 Judging from the output of various provinces and cities, from January to December 2011, Shandong's glass fiber output reached 1.25 million tons, an increase of 18.79% year-on-year, accounting for 33.67% of the country's total output. It is closely followed by Zhejiang, Chongqing and Sichuan, which account for 19.95%, 11.49% and 9.66% of total output, respectively.
Because of this, domestic excellent glass fiber industry manufacturers are paying more and more attention to the research on the industry market, especially in-depth research on the development environment of the company and the changes in customer demand trends. A large number of domestic excellent glass fiber companies have rapidly emerged and gradually become A leader in the glass fiber industry!
