Quartz fiber yarns are formed by twisting fiber filaments of the same diameter into a bundle. The yarn is then wound on a winding cylinder according to different twist directions and number of strands. Quartz fiber yarn has the properties of high temperature resistance, low thermal conductivity, high strength and good insulation. It can be used in a variety of textile processes and is widely used in fiber optic aerospace, semiconductor and other industrial applications.
Quartz fiber yarn is the current dielectric properties of special low, high temperature resistant flexible inorganic materials, can replace the alkali-free glass fiber, high silica oxygen, basalt fibers, etc., can partially replace the aramid, carbon fibers, etc., in the field of ultra-high temperatures and aerospace has a unique advantage; In addition, quartz fibers of the coefficient of linear expansion is small, and has a modulus of elasticity with the temperature increases and increases the rare characteristics.
Properties of quartz fiber yarn:
1. Acid resistance, good corrosion resistance. Stable chemical properties.
2. Low density, high tensile strength. No microcracks on the surface, tensile strength up to 6000Mpa.
3. Excellent dielectric properties: dielectric constant is only 3.74.
4. Resistance to ultra-high temperatures: God Jiu, for example, long-term use temperature 1050 ~ 1200 ℃, softening point temperature of 1700 ℃, thermal shock resistance, longer service life.
5. Insulation, low thermal conductivity, stable performance.
