Fiberglass Roving Yarn

タイトルまたは説明

Fibers produced from high purity (*9.*5%) SiO2. High silica and quartz fibers can be made into rovings or yarns, or woven into fabrics similar to ordinary fiber glass. However, high silica and quartz compared to fiber glass differ in thermal properties. High silica and quartz have very low coefficients of linear thermal expansion, can be heated to ***5°C (***0°F) and plunged into water without damage. The difference between high silica and quartz fibers is the cost and strength. High quality quartz needed for quartz fibers, which is fairly rare, is mined mainly in Brazil, while the raw material for high silica fiber is the same as ordinary glass fiber (common silica sand). The-high temperature strength of quartz fiber is considerably stronger than that of the high silica fiber. Specification Purity ï¼¥*9.*5% Operation Temperatureï¼***0â Densityï¼ 2.2 Elastic Modulusï¼*8Gpa Elongation/breaking Ratioï¼4.6% Filament diameter: ***5 um Application high-temperature insulation: such as rockets, missiles for insulation, earthquake or other high-temperature insulating materials engineering. 2.Used for reinforced plastic: high-temperature production of synthetic resin and high-strength glass fiber reinforced plastic materials. Widely used in aviation, missiles and rockets, and so on. 3.Special cable: use for the foreskin of the cable, used in high temperature on the special-purpose cable. 4.Acid-base for high-temperature filters vacuum tube filled with material: water Rafah as a quartz tube filled with silk material, in order to improve the performance of the tube, and extend the life of vacuum tube.
