E-glass
Also known as alkali-free glass, it is a borosilicate glass. At present, it is the glass fiber with the most widely used glass component. It has good electrical insulation and mechanical properties. It is widely used in the production of glass fiber for electrical insulation. It is also widely used in the production of fiberglass for glass reinforced plastic. Its disadvantage is that it is easy to be Inorganic acid is eroded and therefore not suitable for use in an acidic environment.
C-glass
Also known as medium alkali glass, it is characterized by chemical resistance, especially acid resistance is better than alkali-free glass, but the electrical properties are poor, the mechanical strength is lower than that of alkali-free glass fiber by 10% to 20%, usually the foreign medium-alkali glass fiber contains certain The amount of boron trioxide, while China's medium alkali glass fiber is completely free of boron. In foreign countries, medium-alkali glass fiber is only used to produce corrosion-resistant glass fiber products, such as glass fiber surface felts, and also used to strengthen asphalt roofing materials. However, in China, alkali glass fiber occupies more than half of glass fiber production. (60%), widely used in the reinforcement of FRP and the production of filter fabrics, dressing fabrics, etc., because it is more competitive than alkali-free glass fiber.
