Glass fiber generally refers to the manufacture of glass raw materials, melting at high temperature, drawn with special equipment or with compressed air, high pressure steam injection, centrifugal molding method for producing glassy fibers or filaments. 
 Many varieties of glass fiber, its chemical composition, production methods, morphology, performance and use of the same and, therefore, have a different classification, but according to the shape and length of the fiber can be roughly divided into three categories: 
 A continuous glass fiber or textile glass fiber. Its production method is the melt outflow of the drain board of glass liquid produced by the high temperature materials, high-speed rotating drum drawn fiber bundle made. After textile processing can be made of glass yarn, cloth, tape, rope and roving and other products. 
 Length glass fiber or glass long cotton. It is a root messy single fiber can be made into a mat or yarn, yarn can also be made of cloth, with Given the long glass fiber is a high-speed airflow blowing molten glass liquid drawn into the fiber and then formed by cutting. 
 (3) glass wool. The glass wool is a fiber length of short glass fibers, the morphological organization fluffy, like cotton, also known as glass short cotton. Glass short cotton is processed by steam injection, centrifugal, centrifugal injection and flame injection and other methods. 
 Glass fiber has a small bulk density, low thermal conductivity, good sound absorption, high filtration efficiency, not combustion, corrosion resistance and excellent performance, with its long fibers can be woven into the glass fiber Qiangbu, the hot pressing of glass fiber cloth bonded by the resin decorative plates made of glass fiber reinforced plastic, glass wool glass wool decoration made by hot pressing processing board.
