Ceramic fiber board is a kind of refractory material. Due to its fire resistance and high toughness, it is widely used in various fields. It plays a major role in the thermal insulation of the non-ferrous metal industry. It can also be made into helmets, protective clothing, headgear and gloves in high temperature environments. , boots, etc. In terms of material selection, temperature is the first principle, but many people do not understand why it must be determined according to the use temperature? What happens if used over temperature? The following is a detailed analysis for you.
As a high-temperature refractory thermal insulation product, ceramic fiber boardhas low thermal conductivity and good thermal insulation effect. If the crystal growth of the product is abnormally slow, its properties will become more stable at permissible temperatures, lasting 5-10 years.
If you work in a temperature overload environment for a long time, the development of ceramic fiber board crystals will be accelerated, the pores supported by the fiber structure will be gradually broken, the porosity of the module will be reduced, and the thermal insulation effect will be reduced. Externally, the modules are small in size and even severely squeezed. The module will gradually fall off, damage the furnace body, and bring immeasurable losses.
When the product is used in a furnace environment containing corrosive substances, the temperature of the ceramic fiberboard should be determined according to the fuel in the furnace. If it is used for reducing furnace gas, it is necessary to select the material and calculate the wall thickness according to the composition of the reducing atmosphere, and apply an anti-corrosion coating on the surface. It is precisely because of the manufacturing process, materials and advantages of ceramic fiber board that it can be widely used in various fields and aspects of life.
