Glass fiber chemical is mainly composed of silicon dioxide (SiO2) and three oxidation boron (B2O3), calcium oxide (CAO), 3 oxidation 2 aluminium (Al2O3) and silica based said silicate glass, boron trioxide said borate glass. Alkaline oxide, sodium oxide and potassium oxide fluxing oxides, which can reduce the glass melting temperature and viscosity, the bubble of glass solution can be easily removed, it is mainly through destroying the glass frame, the loose structure, so as to achieve solution to help. The higher the content of sodium oxide and potassium oxide and glass fiber strength, electrical insulation and chemical stability will corresponding decreases with the addition of calcium oxide, 3 oxidation 2 aluminium can constitute a part of the glass network under certain conditions, improve the glass certain properties and process.
Chemical composition of glass fibers making hand to meet requirement of glass fiber physical and chemical properties, and have good chemical stability; on the other hand, to meet the requirements of the manufacturing process, such as proper forming temperature and hardening speed and range of viscosity.
