RCF Ceramic Fiber Bulk
Classification temperature:
- Standard fiber: 1260℃
- Synthetic high-purity fiber:1 260℃·
- Zirconium fiber 1430℃
- Chrome fiber: 1500℃
Product description:
- Standard fiber: Refractory fibers that are produced by means of spun process through careful material selecting by electric melting.
- Synthetic high-purity fiber: Refractory fibers that are produced by means of spun process using the mixture of used alumina and silica.
- Zirconium fiber: Refractory fibers that are produced by means of spun process using the mixture of fused alumina, silica as well as zirconia.
- Chromium fiber: Refractory fibers that are produced by means of spun process using the mixture of fused alumina, silica as well as chrome oxide.
- Ceramic fiber loose cotton owns excellent resistance capacity to chemical erosion. (except hydrofluoric acid, phosphoric acid and strong base, such as Na2O,K2O).
- All materials of bulk fiber can also be produced by the blowing process to make its fiber diameter finer.
- All materials of bulk fiber can be washed with water to reduce its shots content to less than 3%.
- All materials of bulk fiber can be chopped short to make its length shorter.
- Low thermal capacity
- Low thermal conductivity
- Excellent resistance to thermal shock
- Excellent chemical stability
- Excellent thermal stability, not easy to powder at high temperature
- Excellent elasticity at high temperature
- Without binding agents and other corrosive substances Excellent sound absorption performance
Typical applications:
- Secondary products such as slab, paper, irregular parts,
- raw material of textile
- Thermal insulation filling material for corners and complex space
- Filling material for dilatation joint-Filling material for short-term heat insulation repair
