Custom Ceramic Fiber Blanket Manufacturer
The classification of ceramic fiber blankets is primarily based on their chemical composition, performance characteristics, and application scenarios. The common categories are as follows:
Standard Type Ceramic Fiber Blanket
- Basic Composition: Mainly made of alumino-silicate (Al₂O₃ + SiO₂ ≥96%), with Al₂O₃ at 44%-46% and SiO₂ at 45%-55%, plus small amounts of fluxing agents like Fe₂O₃ and CaO.
- Structure: Primarily mullite and glass phases, with fiber diameters of 3–5μm. Forms a porous network structure with porosity >95% and low thermal conductivity.
- Applications: Used in medium-temperature environments such as heating furnaces in metallurgy, boiler linings, and high-temperature pipe insulation.
Polycrystalline Mullite Fiber Blanket
- Chemical Composition: Al₂O₃ ≥72%, SiO₂ about 25%–28%, forming a mullite (3Al₂O₃·2SiO₂) crystal structure.
- Features: Stable crystal phase, long-term use above 1600°C, excellent thermal shock resistance, low shrinkage at ultra-high temperatures.
- Applications: Used in aerospace insulation, high-temperature nuclear equipment, and advanced ceramic sintering kilns.
Biosoluble ceramic fiber blanket
- Chemical Composition: Mainly composed of MgO, CaO, and SiO₂ (e.g., MgO-CaO-SiO₂ system), slowly dissolvable in body fluids.
- Features: Lower heat resistance (long-term use at 600–800°C), environmentally friendly, non-toxic, but lower in strength and corrosion resistance.
- Applications: Temporary insulation, special insulation in medical fields, and short-term thermal protection in industries with strict environmental requirements (different from standard types).
Ceramic fiber blanket with foil
- Features: Surface coated with metal foil (e.g., aluminum foil, stainless steel mesh) to enhance tear resistance, moisture protection, and heat reflection.
- Applications: Used for high-temperature pipe cladding and insulation of industrial equipment requiring wind or water resistance.
Chrome-containing ceramic fiber blanket
- Chemical Composition: Al₂O₃ about 46%–48%, SiO₂ about 50%–52%, added Cr₂O₃ (3%–5%).
- Features: High temperature resistance (1000–1200°C), excellent resistance to reducing atmospheres (e.g., CO, H₂) and molten metal corrosion. Chromium improves oxidation resistance and chemical stability.
- Applications: Used in blast furnaces, non-ferrous metal smelting furnaces, and coal gasification furnaces with reducing gases or molten slag.
Zirconium-containing ceramic fiber blanket
- Chemical Composition: Al₂O₃ about 38%–40%, SiO₂ about 52%–54%, with added ZrO₂ (15%–17%).
- Features: Significantly improved high-temperature resistance (1300–1600°C), low thermal conductivity, strong thermal shock resistance and slag resistance due to zirconia's crystal stability.
- Applications: Used in petrochemical cracking furnaces, high-temperature zones of ceramic kilns, and aerospace insulation components.
