So far, ceramic fiber modules is a kind of thermal insulation material with ideal thermal insulation effect and cost investment. The high cost performance makes ceramic fiber module the darling of thermal insulation for many industrial kilns and electric heating equipment.
However, some high-temperature furnaces are not suitable for using ceramic fiber modules as furnace linings, such as the furnace environment where moisture exists.
What is the reason for this? We should start with the thermal insulation properties of ceramic fiber materials.
The insulation ceramic fiber module is an inorganic refractory material with a porosity of more than 96%. Its thermal insulation effect is achieved through the porosity. If the ceramic fiber module is invaded by water vapor, the original pores will be filled with moisture. Everyone knows that the thermal conductivity of water is very good, so the ceramic fiber module containing moisture will also become a heat conductor. Once the heat is transferred to the steel plate through the module, the steel plate will be deformed, the consequences are unimaginable.
SUNTHERM reminds industrial furnace manufacturers that once they find that the ceramic fiber lining of the furnace is soaked by water, they must immediately stop the furnace and deal with it under the guidance of professionals. In addition, not only ceramic fiber modules, but all fire-resistant cotton (aluminum silicate, glass fiber, etc.) have the same insulation principle. You must pay attention to moisture during transportation, storage, and use.
