Production Process of Kerui RefractoryBlankets

Kerui primarily employs two production processes: blown blankets and spunbonded blankets. The ceramic fiber spunbonded blanket has the features of the longer fiber strands and lower thermal conductivity. It offers superior insulation performance compared to the ceramic fiber blown blanket. As a result, the ceramic fiber spunbonded blanket is a common choice for insulation in pipeline construction.

Features of Refractory Blankets Insulation

• Low Thermal Conductivity: Excellent insulation properties that effectively reduce heat loss.
• Outstanding Chemical Stability: Corrosion-resistant and suitable for various chemical environments.
• Excellent Thermal Stability: Maintains performance stability at high temperatures, with dimensional stability under heat.
• High Tensile Strength: Resistant to stretching and less prone to breaking.
• Vibration Resistance: Maintains performance even in vibrating environments.
• Low Heat Capacity: Responds quickly to temperature changes, saving energy.
• Excellent Sound Absorption: Reduces noise transmission.
• Easy to Handle: Lightweight and flexible for construction operations.

Applications of Refractory Blankets

• Insulation and Lining Materials: The linings of furnaces, kilns, reformers, and boilers; reusable insulation for steam and gas turbines; and high-temperature kiln insulation.
• Seals and Gaskets: These include furnace door linings, high-temperature gaskets, expansion joint seals, and removable insulation blankets to alleviate welding stress.
• Specialized Applications: Covers nuclear insulation applications, thermal insulation for reactors, glass furnace crown insulation, and linings for outdoor steam generators.
• Fire Protection and Filtration: Involves fireproofing for pressure and low-temperature containers, sealing for soaking pits, high-temperature filtration, and linings for incinerators and chimneys.
• Mold Packaging: Encompasses packaging for investment casting molds and removable mold packaging solutions.
