The main purpose of insulation is to reduce thermal loss of the heat media during conveying, save fuel, and ensure temperature. The China insulation thermal material can be divided into coating, winding, filling, irrigation, spraying, and so on according to the performance and construction methods. Ceramic fiber board is a lightweight refractory China insulation thermal material that has emerged in the past ten years.
To determine the insulation performance of a material, start from the following aspects:
Thermal conductivity: It is a parameter of the insulation material transmission of heat capacity, which reflects the thermal conductivity of the material, and is the main thermal physical characteristics of China insulation thermal material. The heating coefficient of the ceramic fiber plate is only 0.145W/(m.k) when the ceramic fiber board is 600 °.
Rong heavy: There is a reasonable capacity for each kind of China insulation thermal material, and it has a small thermal conductivity and better thermal insulation effect in this interval. In the engineering, for the energy conservation and the weight of the insulation structure, the insulation material with a small amount of capacity should be used as much as possible. The capacity of the ceramic fiber plate is 280kg/m3, which is 1/4 of the light resistance and refractory rotation.
Use temperature: refers to the limit temperature that can be afforded for long -term and reliable work insulation materials. The long-term use temperature of ceramic fiber board is between 850-1300 degrees. It is a product with higher temperature resistance of Mo Lai stone fiber in China insulation thermal material.
Compression intensity: Ceramic fiber board is a semi -hard heating material, which is generally not damaged when compressed loads.
Wiring expansion coefficient: If the line expansion coefficient of the insulation material is large, the internal deformation will be deformed to produce a large stress after heating. Different from conventional China insulation thermal materials, ceramic fiber plates are not heated and do not swell. There is no need to reserve expansion seams during use.
Chemical performance: Different use environments require that thermal insulation materials have good chemical stability. Antichen and alkali, anti -corrosion, and not easy to oxidize, ceramic fiber plates performed well in this regard.
The thickness of the insulation layer: In order to reduce the heat dissipation loss of the thermal insulation structure, the thickness of the China insulation thermal material layer should be calculated according to the method of ‘economic thickness’. Ceramic fiber boards can customize the size flexibly according to the environment.
It can be seen that compared with other thermal insulation materials, the thermal insulation effect of ceramic fiber plates is still prominent.
