Ordinary ceramic fiber is also called aluminum silicate fiber, because one of its main composition is alumina, and aluminum oxide is the main ingredient of porcelain, so it names ceramic fiber. Adding zirconia or chrome oxide can further increase the temperature of ceramic fiber.
Ceramic fiber products refer to those mechanicals which use ceramic fiber as raw materials through processing with light weight, high temperature resistance, good thermal stability, low thermal conductivity, low heat and mechanical shock resistance and other advantages. Those products are dedicated to all kinds of high temperature, pressure and easily worn environment. Ceramic fiber is a kind of excellent refractory ceramic fiber products. It has light weight, high temperature resistant, small heat capacity, well thermal insulation performance, non-toxic and other advantages. So far, China's now ceramic fiber manufacturers are more than two hundred, but the manufacture technique with temperature of or under 1425 ℃ (including zirconium fiber) only has spun fiber blanket and blown fiber blanket.
Specifications:
1. Fiber diameter: spun fiber is thicker with 3.0-5.0 micrometer diameter; while blown fiber has 2.0-3.0 micrometer one;
2. Fiber length: spun fiber is 150-250mm; blown fiber is 100-200mm;
3. Thermal conductivity: blown fiber blanket is better than spun one due to its thinness;
4. Tensile strength: spun fiber is better than blown one because of its thickness;
5. Application in manufacturing ceramic fiber module: spun fiber blanket is better. During folding process in production, blown fiber blanket is easy to be broken or tear, while spun fiber one will fold compactly and cannot be easily destroyed. The quality of module will directly influenced it of brusque;
Application：
1. Door sealing and front curtain of various thermal insulation industrial furnace;
2. High temperature flue, air hose bush and inflated joint;
3. Petroleum chemical industry equipment, containers, pipes heat insulation and preservation;
4. Protective clothing, gloves, caps, helmet, boots used in high temperature places;
5. Heat shield of automobile engine, Oil engine exhaust pipe parcel, composite brake pad of high-speed racing car;
6. Pump and compressor transmitting high temperature fluid and gas, valve packing and gasket;
7. Fireproof doors, fireproof curtain, fire blanket, insulation covering and other fire protection products;
8. Heat insulation, thermal insulation material and brake pad applied to aerospace industry;
9. Fire prevention insulation layer or automatic fire curtain in some important places in high-grade office buildings such as archives, coffers, safe case, etc.
