What is a ceramic fiber module?
The main raw material of ceramic fiber module is ceramic fiber blanket, which is made by folding and compressing seramika tolali adyol.
It is mainly used in industrial kilns, such as lining insulation of kilns in petrochemical industry, lining insulation of kilns in metallurgical industry, lining insulation of kilns in building materials industry such as ceramics and glass, lining insulation of heat treatment furnaces in heat treatment industry, and lining insulation of other industrial kilns.

ceramic fiber module density
Witness range
International standard: There is only one standard for density in the world, which is 220Kg/m3
Practical application: According to the furnace type, harorat, combustion medium, temperature rise requirements of the heat treatment furnace, the density of the refractory ceramic fiber module is set at 200-240Kg/m3Density influence
Issiqlik o'tkazuvchanligi: The greater the density, the lower the thermal conductivity, but after exceeding a certain range, the thermal conductivity no longer decreases, but tends to increase
Insulation effect: Too high density may cause the surface fiber of the ceramic fiber module to break and be carried away by the furnace wind, and the furnace lining gradually becomes thinner, resulting in the attenuation of thermal insulation performanceOptimum density
Porous fiber materials have an optimal volume density with the minimum thermal conductivity. The volume density of ceramic fiber on the hot surface of the layered ceramic fiber wall lining is specified as 130-160Kg/m?, and the volume density of ceramic fiber on the hot surface of the flat-laid composite furnace lining is specified as 200-240Kg/m?
Advantages of ceramic fiber module anchoring
Benefits for metal anchors
Temperature: The anchoring system is away from the hot surface of the component, so that the metal anchor is at a relatively low temperature, which improves the safety of the anchoring. Masalan, in some kiln applications, it can reduce the risk of damage to the metal anchor due to high temperature.
Stability: The ceramic fiber module can be firmly fixed in the corresponding position to ensure the stability of the entire structure. Masalan, in industrial kilns such as tunnel kilns, when facing complex thermal and mechanical stresses, the stable anchoring can prevent the module from shifting.
Improvement of the overall performance of ceramic fiber modules
Gap treatment: During the module installation process, the elastic fiber blanket can resist mechanical external forces, and the elasticity of the fiber blanket can compensate for the deformation of the furnace shell, so that no gaps are generated between the components. Masalan, when the furnace shell may be deformed due to thermal expansion and contraction, the anchoring helps to keep the modules tightly connected.
Energy-saving effect: Due to the anchoring, the module is installed firmly, and the low thermal conductivity can be better utilized, which brings high energy-saving effects and helps to reduce heat loss during the operation of kilns and other equipment.
