1600°C High-Temperature Insulation Polycrystalline Alumina Needled Blanket

Product Description:

1600°C High-Temperature Insulation Polycrystalline Alumina Needled Blanket is a high-performance insulating material specifically engineered for extreme industrial thermal environments. Manufactured using the sol-gel method in combination with advanced needling technology, the product features high purity, long fibers, and a uniform structure. Its outstanding comprehensive properties enable it to maintain exceptional stability and mechanical strength under extreme operating conditions at and above 1600°C, making it an ideal solution for demanding high-temperature applications in industries such as metallurgy, ceramics, petrochemicals, and aerospace.

The primary component of the 1600°C High-Temperature Insulation Polycrystalline Alumina Needled Blanket is high-purity polycrystalline alumina, allowing for long-term service temperatures up to 1600°C. It exhibits excellent resistance to pulverization and grain growth at elevated temperatures, effectively extending equipment lifespan and ensuring process safety. The unique needling process creates a three-dimensional network structure among the fibers, endowing the blanket with outstanding tensile strength and tear resistance. It maintains excellent structural integrity during installation, cutting, and under high-temperature vibration conditions, facilitating easy construction and preventing damage. The blanket's internal structure features a high-porosity microporous network that effectively inhibits heat conduction and convection, significantly reducing heat loss. Its low heat capacity enables rapid response during fast heating and cooling cycles, contributing to energy savings and consumption reduction. The polycrystalline alumina material possesses strong chemical inertness, resisting erosion from most chemical media (with the exception of hydrofluoric acid and concentrated alkalis), as well as molten metals, steam, and high-temperature flue gas. Under prolonged high-temperature service, the product exhibits extremely low shrinkage and is resistant to cracking or deformation, ensuring a tight furnace lining seal, effectively preventing thermal short-circuiting, and enhancing overall thermal insulation performance.
