Classification of refractory fiber products at home and abroad

Reinforcing fibers can be mainly classified into the following categories: 1. **Ceramic fibers**: Also known as refractory fibers, ceramic fibers have an extremely high heat resistance, typically exceeding 1000°C. It is mainly used to manufacture insulation materials and filling materials for high-temperature industrial furnaces. 2. **Mineral wool fibers**: Mineral wool fibers are a type of natural inorganic fiber, with a fire resistance temperature typically above 600°C. Mineral wool fibers are primarily used as thermal and sound insulation materials in construction. 3. **Glass fiber**: Glass fiber is primarily made from quartz sand, quartz stone, quartz sand, and other inorganic substances. It has strong fire resistance and is mainly used in the manufacture of insulating materials and fireproof products. 4. **Alkali metal silicate fibers**: Alkali metal silicate fibers are high-strength refractory fibers whose fire resistance temperature can reach over 1000°C. This type of fiber is mainly used to manufacture insulation materials for high-temperature industrial furnaces. 5. **Aluminate fibers**: Aluminate fibers are primarily made from high-purity alumina and silicates, and their fire resistance temperature can reach over 1300°C. This type of fiber is mainly used to manufacture insulation materials for high-temperature industrial furnaces. 6. **Zirconia fibers**: Zirconia fibers are high-performance refractory fibers, with a fire resistance temperature of over 2000°C. This type of fiber is mainly used to manufacture insulation materials for high-temperature industrial furnaces. The above are the common classifications of various refractory fiber products available domestically and internationally. In reality, the properties and applications of different refractory fibers vary, and the choice should be made based on actual needs. .
