Industrial Ceramic Fiber Blanket

Ceramic fiber blanket is a lightweight, high-temperature refractory insulation material made from high-purity alumina silicate fibers through a needle-punching process. It possesses excellent high-temperature resistance, low thermal conductivity, strong chemical stability, and good thermal shock resistance, making it a commonly used thermal insulation material in modern industrial furnaces and high-temperature equipment.

I. Main Characteristics of Ceramic Fiber Blanket

The temperature resistance range of ceramic fiber blankets is generally between 950°C and 1430°C, and it is divided into several series, including ordinary, standard, high-alumina, and zirconium-containing types. This product contains no binders and does not produce smoke or odor during use. Its low thermal conductivity and small heat capacity significantly improve thermal energy utilization efficiency and reduce energy loss. In addition, ceramic fiber blankets have good mechanical strength and flexibility, making them easy to cut and install.

II. Main Application Areas of Ceramic Fiber Blanket

In the industrial field, ceramic fiber blankets are widely used in metallurgy, petrochemicals, power, cement, ceramics, glass, and other industries. Common applications include:

Insulation layers for the inner and back linings of industrial furnaces, heat treatment furnaces, and heating furnaces;

Insulation for heat pipes, flues, reaction towers, and storage tanks;

High-temperature sealing, expansion joint filling, and fireproof insulation;

High-temperature protection systems in aerospace, shipbuilding, and other industries.

III. Installation and Usage Recommendations for Ceramic Fiber Blankets

During construction, select the appropriate model based on the operating temperature, ensuring the blanket surface is flat and overlaps are tight to minimize heat loss. For long-term high-temperature environments, zirconium-containing ceramic fiber blankets are recommended, as they offer superior thermal shock resistance and a longer lifespan.

IV. Industry Development Trends for Ceramic Fiber Blankets

With the advancement of energy-saving and environmental protection policies and the upgrading of high-temperature industrial technologies, ceramic fiber materials are gradually replacing traditional refractory insulation bricks. In the future, the industry will develop towards high strength, ultra-low thermal conductivity, and environmental friendliness. Simultaneously, automated production and the application of new raw materials will further improve the quality of ceramic fiber blanket products.
