In modern industrial production, refractory is an indispensable part, especially in high temperature environment, its performance is directly related to the safe operation and production efficiency of industrial equipment. As a new type of refractory, ceramic fiber board is gradually favored by the market for its excellent performance and wide application fields. This paper will introduce the performance characteristics, application fields and future development trend of ceramic fiber board in detail.

I. Performance characteristics of ceramic fiber board

(1) Low thermal conductivity and low thermal capacity

Ceramic fiber board has a very low thermal conductivity, usually around 0.085 W/m·K (density 285 kg/m), which can effectively prevent heat transfer even in high temperature environment. At the same time, its low thermal capacity makes it perform well in the process of rapid heating and cooling, and can respond to temperature changes quickly and reduce energy consumption.

(2) High temperature stability and thermal shock resistance

Ceramic fiber board can work stably for a long time at the temperature as high as 1350℃. Its main components include alumina (Al₂O₃) and silica (SiO₂), which have high chemical stability and are not easily eroded by chemicals. In addition, it has excellent thermal shock resistance, can keep the structure intact under the condition of rapid temperature change, and is not easy to crack or deform.

(3) High strength and processability

Ceramic fiber board has high strength, its tensile strength can reach 0.5 MPa, and it can bear certain mechanical load. At the same time, it also has good processing performance, and can be cut, drilled and installed as required, which is convenient for on-site construction.

(4) Good acoustics and fire resistance.

Ceramic fiber board has excellent sound insulation and absorption performance, which can effectively reduce noise transmission. In addition, it also has excellent fire prevention performance, which can effectively prevent the fire from spreading and provide guarantee for the safety of industrial equipment and personnel.

II. Application fields in ceramic fiber board

(1) Industrial furnaces

Ceramic fiber board is widely used in lining materials of various high-temperature industrial furnaces, such as heating furnaces, heat treatment furnaces and ladle covers in metallurgical industry, boilers and gas turbines in electric power industry, and high-temperature reaction equipment and heating equipment in petrochemical industry. Its excellent thermal insulation and thermal shock resistance can effectively improve the thermal efficiency of the furnace and prolong the service life of the equipment.

(2) Thermal insulation of high temperature pipeline

In high temperature pipeline system, ceramic fiber board can be used as insulation material to prevent heat loss and reduce energy consumption. Its low thermal conductivity and good mechanical properties enable it to adapt to the complex shape and installation requirements of pipelines.

(3) Fire prevention and heat insulation

Ceramic fiber board can also be used in the field of building fire prevention, such as fire doors, firewalls and fire partitions. Its excellent fire prevention performance and heat insulation performance can effectively prevent the fire from spreading and gain time for personnel evacuation and fire fighting.

(4) Other applications

Ceramic fiber board can also be used for heat insulation and sound insulation materials in automobile industry, high-temperature insulation materials for electronic equipment, and high-temperature filtration materials in environmental protection industry. Its wide application field makes its market demand increase continuously.

III. Development trends in ceramic fiber board

With the continuous development of industrial technology, the performance requirements of refractories are getting higher and higher. In the future, ceramic fiber board will develop in the direction of higher strength, higher temperature stability and lower thermal conductivity to meet the special needs of different industrial fields.

(2) Environmental protection

Under the background of increasingly strict environmental protection policies, the production process in ceramic fiber board will pay more attention to environmental protection. By optimizing the production process, energy consumption and pollutant emission can be reduced, and sustainable development can be realized.

(3) Multifunctional

In the future, ceramic fiber board will not only be limited to a single heat preservation or fire prevention function, but also integrate multiple functions, such as heat insulation, sound insulation, fire prevention and corrosion prevention, to meet the diverse needs in the complex industrial environment.

(4) customization

With the intensification of market competition, users' personalized demand for ceramic fiber board will continue to increase. In the future, ceramic fiber board will develop towards customization, providing products with different specifications, performances and shapes according to the specific needs of users.

IV. Conclusion
