Key Advantages of Kinsyn Mullite Honeycomb Ceramics
1. Superior Thermal Performance • High Al₂O₃ content (60%-70%) enhances material properties. • Excellent thermal conductivity (≥2W/m·K) ensures uniform temperature distribution and minimizes thermal stress. • High specific heat capacity (1150J/kg·K) helps improve heat retention. • High bulk density (780-810kg/m³) due to the molecular weight advantage of Al₂O₃. • Strong temperature resistance: designed for operation up to 1300°C, with a softening point around 1400°C.
2. Efficient Heat Exchange • Large specific surface area (e.g., 890/950㎡/m³ for 40/43-cell structures) enhances heat transfer efficiency.
3. High Mechanical Strength • Strong compressive strength (28MPa at 150mm height, 24MPa at 300mm height) improves resistance to thermal stress and mechanical loads.
4. Excellent Thermal Shock Resistance • Can withstand temperature fluctuations up to 350°C, reducing the risk of cracking.
5. Precision & Stability • High dimensional accuracy ensures easy installation with minimal misalignment, allowing for efficient maintenance and potential reuse in certain cases.
6. Optimized Structural Design • Thick outer walls (2.0mm) enhance structural support. • Thin inner walls (0.65/0.62mm for 40/43-cell structures) improve heat transfer and recovery.
7. High Porosity & Low Pressure Drop • 65% porosity (for 40/43-cell structures) ensures smooth airflow with minimal resistance.
8. Reliable Durability • Designed for long-term use, with resistance to slag adhesion, corrosion, and deformation, contributing to an extended service life in typical applications.
9. Strong Chemical Resistance • High acid and alkali resistance (≥98%), making it suitable for demanding environments.
