Quartz yarn has properties such as high temperature resistance, low thermal conductivity, high strength, and good insulation. It can be used in a variety of textile processing processes and is widely used in fiber optic aviation, semiconductor and other industrial fields. Quartz fiber yarn is currently a flexible inorganic material with extremely low dielectric properties and extremely high temperature resistance. It can replace alkali-free glass fiber, high silica fiber, basalt fiber, etc., and can partially replace aramid, carbon fiber, etc., in ultra-high temperature and aerospace applications. It has unique advantages in the field; in addition, the linear expansion coefficient of quartz fiber is small, and it has the rare characteristic that the elastic modulus increases with increasing temperature.
Properties of quartz fiber yarn:
1. Good acid resistance and corrosion resistance. Chemical properties are stable.
2. Low density and high tensile strength. There are no micro-cracks on the surface and the tensile strength is as high as 6000Mpa.
3. Excellent dielectric properties: dielectric constant is only 3.74.
4. Ultra-high temperature resistance: Taking Shenjiu as an example, the long-term use temperature is 1050~1200℃, the softening point temperature is 1700℃, it is thermal shock resistant and has a longer service life.
5. Insulation, low thermal conductivity, stable performance.
Application scope of quartz yarn:
1. Can be used as space shuttle radome, aircraft electromagnetic window, and electronic countermeasures device;
2. Dental posts and prosthetic bone reinforcement materials
3. Televisions, radios, computers, computers, mobile communication equipment
4. It has good high temperature resistance and can resist the strong thermal shock caused by the friction between the missile radome and the atmosphere during high-speed flight.
5. Aircraft engines, fuselage fireproof partitions, semiconductor and optical fiber manufacturing
6. High-temperature catalyst carrier materials (automobile exhaust treatment, industrial air purifiers)
7. Roller sleeves for rollers of automotive glass tempering furnaces
8. Can be made into high temperature and hot acid gas and liquid filter materials
