Ceramic fiber products have a thermal conductivity that is their physical property. This indicates their ability to heat transfer. Thermal conductivity is a measure of how difficult it is to heat transfer. This means that heat preservation and energy savings are better. The thermal conductivity for ceramic fiber products depends on the following factors: temperature, porosity, pore structure, bulk density, fiber diameter, fiber moisture, working environment, and fiber direction.
Ceramic fiber products are made of natural kaolin, which is melted in an electric furnace and then blown or spun using resistance. The temperature for continuous use can reach 1000 and the temperature for short-term usage can reach 1260. China invested successively in the construction of specialized manufacturing facilities for ceramic fiber products. They also mass produced ceramic fiber cloth, paper and buckles.
Ceramic fiber material is a lightweight, fibrous, refractory thermal insulation material and energy saving material. It combines the best of traditional thermal insulation with refractory materials. It is incombustible, heat resistant, stable thermally, light weight, and has a tasteless, non-toxic, safe, and tasteless characteristic. It is used primarily in industrial furnaces and heat treatment equipment. It is widely used in advanced technological and scientific fields like engineering, metallurgy and chemical industry, petroleum and transportation, shipbuilding and electronics, national defense and aerospace, and nuclear power.
Ceramic fiber products are ideal for use in smoke-tight gaskets such as duct flange gaskets. Ceramic fiber rope and ceramic paper are two options for sealing ceramic fiber products.
Ceramic fiber rope: This ceramic fiber rope is made from ceramic yarn and is used as a thermal insulation material. This rope is a great replacement for asbestos rope. It is commonly used to wind high-temperature cables and pipes.
Ceramic fiber paper: This is ceramic fiber paper made from blown ceramic cotton after being washed and bonded in a vacuum. This material is ideal for high-temperature gaskets, sealing and thermal insulation, heat preservation, and other applications that require high strength and flexibility.
Quilts made of ceramic fiber
The ceramic fiber product's main feature is its thermal insulation. 90% of the material is made up of air holes. The thermal conductivity for water at 0 is 0.52 W/mK. However, if the water in the ceramic fiber becomes ice, its thermal conductivity is 2.32 W/mK. The thermal conductivity of water, under the same conditions is nearly 20 times greater than that of water. Air and Ice The thermal conductivity of ice is almost 20 times greater than that for water. To ensure ceramic fibers' thermal insulation, humidity must be controlled in ceramic fiber products' environment.
