Glass fiber raw materials and product characteristics: 1. The main raw materials for the production of glass fiber are: quartz sand, alumina and pyrophyllite, limestone, dolomite, boric acid, soda ash, mirabilite, fluorite. 2. The main components of glass fiber are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc. 3. Glass fiber characteristics: melting point 680 ℃ boiling point 1000 ℃, density 2.4~2.7g/cm3 4. Glass fiber has high temperature resistance, no effect on strength when the temperature reaches 300℃, no loss of strength below 500℃, non-combustible, corrosion resistance, good heat and sound insulation, high tensile strength, and good electrical insulation.
Fiberglass Roving
Pool kiln drawing is an advanced technology for producing glass fiber, and its scale and production capacity are far greater than crucible drawing. The technical feature is that it adopts heavy oil or gas heating unit kiln, the powder is directly melted into glass, and the forming channel heated by gas is used to simultaneously draw various specifications of glass fiber strands from multiple slip plates. It has the advantages of large production scale, high efficiency, low energy consumption, and good product quality. It can meet the requirements of 800 to 4000 hole large slat wire drawing. It is the best method to produce high-quality, low-cost glass fiber materials.
