Quartz fiber production line

Quartz fiber (SiO2 with purity > 99.99%) has become a key industrial material due to its high temperature resistance (long-term 1200°C), low expansion, and high insulation. Its main uses include:

1. High temperature protection
– Aerospace: spacecraft insulation tiles, rocket nozzle coatings, to resist the ultra-high temperature of re-entry into the atmosphere.
– Industry: kiln linings, fire blankets, energy saving and extending equipment life.
– Firefighting: lightweight fireproof clothing, escape blankets, flame retardant and flexible.

2. Lightweight composite materials
– Aerospace: Aircraft radomes and satellite brackets, which are more than 30% lighter than metal.
– New energy: Battery shells and hydrogen fuel tank reinforcement layers, which have both strength and corrosion resistance.

3. Electronics and optics
– 5G communications: high-frequency circuit substrates, reducing signal loss.
– Optical fiber: assisting preform molding and improving transmission efficiency.
– Laser: ultraviolet optical fiber, used for precision lithography and medical equipment.

4. Environmental protection and nuclear energy
– Filtration: high temperature filter bags in waste incineration plants to intercept toxic particles.
– Nuclear facilities: radioactive gas filtration systems, radiation-resistant and easy to clean.

5. Special fabrics
– Flexible seals: gaskets for high-temperature equipment, protective layers for joints in space suits.
– Clean materials: dust-free wipes for semiconductor factories, zero pollution residue.
