Ceramic fiber module is an efficient thermal insulation and fireproof material, which is widely used in furnace lining and thermal insulation layer of high temperature equipment. In order to ensure its long-term reliable operation and prolong its service life, the following are some maintenance suggestions:

I. Waterproof and moistureproof

Although ceramic fiber module is resistant to high temperature, it is sensitive to moisture. Once eroded by water, its thermal insulation performance will be greatly reduced. Therefore, it is necessary to ensure that the module is away from humid environment and avoid direct contact with moisture.

II. Prevention of mechanical damage

The internal structure of ceramic fiber module is interwoven with fibers, which has relatively low strength and is easy to be damaged by bumping. During installation and use, mechanical impact on the module should be avoided.

III. Prevention of wind peeling

In the kiln environment with high wind speed, the surface fibers are easily washed away by airflow and peeled off. Even if the surface is sprayed with curing agent, long-term air erosion will lead to damage. Therefore, the direct impact of airflow on the module surface should be minimized.

IV. Regular inspection and cleaning

Regular inspection: check the appearance of the module regularly to see if there are any signs of damage, aging or deformation. Once problems are found, they should be dealt with in time.

Cleaning treatment: keep the periphery of the module clean and avoid the accumulation of pollutants such as dust and grease. When cleaning, clean tools should be used to avoid washing the module directly with water.

V. Timely replacement and repair

Replace the module: after a long period of use, the thermal insulation performance of the module will gradually decline. When obvious damage or performance degradation is observed, a new module should be replaced in time.

Repair the gap: If there is a gap larger than 5mm between modules, it should be filled with ceramic fiber blanket of the same grade to ensure that the gap is tightly filled.

VI. Surface spraying curing agent

In order to enhance the wind erosion resistance and erosion resistance of the module surface, high temperature curing agent can be sprayed on the module surface. The ceramic hard shell formed by curing agent can effectively protect the fiber surface and prolong the service life of the module.

VII. Avoid excessive temperature changes

In the process of using ceramic fiber module, we should try our best to avoid drastic temperature changes, because frequent thermal expansion and cold contraction may lead to module damage.

VIII. Professional Installation and Maintenance

It is suggested that a professional insulation team should install and maintain the module to ensure the construction quality and the service life of the module.

Through the above measures, the service life of ceramic fiber module can be effectively prolonged, its heat insulation and fire prevention performance can be improved, and the safe operation of high-temperature equipment can be ensured.
