Is quartz wool insulation material?
Quartz wool is a kind of quartz fiber.A fabric made from high-purity silica and natural quartz crystals; shaped like cotton.
Method: (1) a quartz rod or tube oxyhydrogen flame melt drawing, then the oxyhydrogen blowpipe blowing, made of a diameter of 0.7 ~ 1 m quartz wool; (2) the flame melting quartz with high speed airflow form short fiber and mat; (3) the quartz wires or rods at a constant speed the oxyhydrogen flame or gas flame, high speed after softening into a longwire.
Purity 99.95%, density 2.2g/cm3. Tensile strength 7GPa; tensile modulus 70GPa. It has heat resistance, corrosion resistance and softness. High strength maintaining rate, stable size, thermal shock resistance, chemical stability, light transmission and electrical insulation under high temperature. Enhanced filament diameter 4~10 m, fiber diameter as quartz cotton varies depending on the use, about 0.7 to 10 mu m.
Reinforcement used primarily as electrical insulating materials, heat insulation materials, and composites. Used in aircraft head, radome, rocket tail nozzle, space vehicle ablation material, optical fiber and other thermal insulation materials.
