High temperature resistance performance:
Ceramic fibers can withstand extremely high temperatures, generally with long-term use temperatures above 1000 ℃. Some ceramic fiber products can even work in high-temperature environments ranging from 1200 ℃ to 1400 ℃ for a long time. For example, in the lining materials of some high-temperature industrial kilns, ceramic fibers can stably play a role in insulation and fire prevention, effectively protecting the steel structure of the kiln from high-temperature erosion.
In a short period of time, ceramic fibers can withstand higher temperature shocks. For example, in the event of sudden high temperatures such as fires, ceramic fibers can maintain structural stability and will not quickly melt, burn, or deform due to high temperatures, saving valuable time for personnel evacuation and firefighting rescue.
Low thermal conductivity: Ceramic fibers have very low thermal conductivity, which means they can effectively prevent heat transfer. During a fire, ceramic fibers can slow down the spread of flame heat to the surrounding environment and objects, reducing the speed of fire spread and the degree of harm. At the same time, low thermal conductivity also makes ceramic fibers widely used in the field of thermal insulation, which can reduce energy consumption and heat loss.
Good chemical stability: Ceramic fibers have good chemical stability and are not corroded by most other chemical substances except strong alkali. In the event of a fire, even when exposed to various chemical substances such as exhaust gases and corrosive gases generated by combustion, ceramic fibers can maintain their stability and will not undergo chemical reactions that would reduce their fire resistance.
Non combustibility: Ceramic fibers themselves are non combustible materials and will not burn or produce open flames at high temperatures like organic materials. This makes ceramic fibers highly reliable in the field of fire prevention, effectively preventing the spread and propagation of flames, and playing a role in fire isolation.
Good structural stability: Ceramic fibers have high tensile strength and good toughness, and can maintain structural integrity in high temperature environments. Even under external impact or vibration, ceramic fibers are not easily broken, detached, or scattered, and can always maintain good fire resistance.
In summary, ceramic fibers have excellent fire resistance and are an ideal fire-resistant material widely used in various high-temperature, high-pressure, and wear-resistant environments, such as industrial kilns, aerospace, construction, chemical engineering, and other fields.
