The general concept of glass is a hard and fragile object, and it is not suitable as a structural material. However, if it is drawn into a wire, its strength is greatly increased and the glass fiber is soft, so that it can be excellent after being given a shape with a resin. Structural materials. The glass fiber increases in strength as its diameter becomes smaller. CAS NO: 14808-60-7 Molecular Structure Feature introduction Raw materials and their applications: Glass fiber is more resistant to temperature than non-combustible, anti-corrosive, heat-insulating and sound-insulating (especially glass wool), high tensile strength and good electrical insulation (such as alkali-free glass fiber). However, it is brittle and has poor abrasion resistance. Glass fiber is mainly used as electrical insulation material, industrial filter material, anti-corrosion, moisture-proof, heat insulation, sound insulation and shock absorption materials. It can also be used as a reinforcing material to make reinforced plastics (see color drawings) or reinforced rubber, reinforced plaster and reinforced cement. The use of organic materials to cover glass fiber can improve its flexibility, and can be used to make packaging cloth, window screen, wall covering, covering cloth, protective clothing and electricity and sound insulation materials. As a reinforcing material, glass fiber has the following characteristics. These characteristics make the use of glass fiber much wider than other kinds of fibers, and the development speed is far ahead of its characteristics as listed below: (1) High tensile strength and small elongation (3%). (2) High modulus of elasticity and good rigidity. (3) The amount of elongation in the elastic limit is large and the tensile strength is high, so the absorption impact energy is large. (4) It is an inorganic fiber, which is incombustible and chemically resistant. (5) The water absorption is small. (6) Scale stability and heat resistance are good. (7) It has good processability and can be used as a product of different forms such as strands, bundles, felts and woven fabrics. (8) Transparent and transparent to light. (9) The development of a surface treatment agent excellent in adhesion to a resin is completed. (10) The price is cheap. (11) It is not easy to burn, and it can be melted into glassy beads at high temperature. Main ingredient Its main components are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc., according to the alkali content of the glass, can be divided into alkali-free glass fiber (sodium oxide 0% to 2%, belonging to aluminum Borosilicate glass), medium alkali glass fiber (8% to 12% sodium oxide, sodium or calcium silicate glass containing boron or boron) and high alkali glass fiber (more than 13% sodium oxide, sodium calcium) Silicate glass).
