- Advantages: Resistant to strong acids and alkalis, suitable for high-temperature furnace linings and precision components, with a long service life.
- Limitations: High thermal conductivity (not suitable for insulation), no sound absorption function, difficult to process, and high cost.
- CVSIC Features: High-purity alumina ceramic (AL₂O₃ ≥ 99%), specifically designed for high-temperature structural components, and can be used in combination with ceramic fibre blankets.
Why Choose CVSIC Ceramic Fiber Blanket
CVSIC ceramic fiber blankets excel in high-temperature resilience, chemical stability, and construction ease:
- Ultra-High Temperature Performance: CV1600 withstands 1600°C, surpassing rock wool (1000°C) and glass wool (600°C), perfect for extreme environments like new energy equipment.
- Low Thermal Conductivity: With a low thermal conductivity of 0.15–0.29 W/m·K (600–1000°C), CVSIC blankets improve energy efficiency by 15–20%.
- Lightweight Construction: With a density of 64-170 kg/m³—far lighter than alumina ceramics (3500 kg/m³)—it ensures easy cutting and installation, reducing labor costs.
- Versatility: Combining thermal insulation, fire resistance, and noise reduction (10–18 decibels), CVSIC ceramic fibre blankets outperform options with high-temperature or acoustic limitations.Chemical Stability: Resistant to acid and alkaline corrosion, CVSIC blankets excel in complex environments, such as the the petrochemical and metallurgical industries.
