Glass fiber has several specifications
High strength glass fiberIt is characterized by high strength and high modulus. Its tensile strength of single fiber is 2800MPa, which is about 25% higher than that of alkali free glass fiber, and the modulus of elasticity is 86000MPa, which is higher than that of E- glass fiber. The FRP products they use are mostly used in military, space, bulletproof armor and sports equipment. But because of the high price, it can not be popularized in the civil field, and the output of the whole world is about several thousand tons.
C- glassAlso known as alkali glass, which is characterized by chemical resistance, especially acid resistance is better than that of non alkali glass, but the electrical performance is poor, the mechanical strength is lower than the non alkali glass fiber from 10% to 20%, three a certain amount of boron oxide containing alkali glass fiber usually abroad two, while alkali glass fiber in China is completely free B. In foreign countries, alkali glass fiber is used for the production of glass fiber products such as corrosion, used in the production of glass fiber mat, also for strengthening the asphalt roofing materials, but occupies more than half of the glass fiber production in the medium alkali glass fiber (60%), widely used in FRP and filter fabric, fabric bandage such as the production, because the price is lower than the non alkali glass fiber and has strong competitiveness.
E- glassAlso known as alkali free glass, is a borosilicate glass. There is a glass fiber components widely used in glass, with good mechanical properties and electrical insulation, widely used in the production of glass fiber insulation, are widely used for glass fiber production of glass steel, it is easy to be inorganic acid erosion, it is not suitable for use in acidic environment.
