Ceramic fiber insulation is a high-efficiency energy-saving thermal insulation material. The material itself has the characteristics of ordinary fibers, but also has the high temperature, corrosion and oxidation resistance that ordinary fibers do not have. It is more important to avoid general fire resistance. The brittleness of the material has replaced the traditional heavy refractory bricks to a certain extent and has been used as an industrial kiln wall lining material. First, the thickness of the kiln has been reduced by 1/2, and the mass has been reduced by 60-80%. The steel used for building the kiln has been saved by 30-50%, not only saving the cost of kiln It also greatly reduces the load of the steel structure of the kiln, thereby extending the life of the furnace body. Second, the use of lightweight, low thermal conductivity and low heat capacity fiber materials as the kiln wall can reduce the surface temperature , Speed up the kiln heating speed, thereby reducing the energy consumption in the furnace temperature operation control, which has a very significant energy-saving effect on the start-up and shutdown of the heating furnace.
Therefore, ceramic fiber insulation supplier believes that: the most important advantage of industrial kiln built with ceramic fiber as the kiln wall is energy saving.
Application as a filter material:
Compared with traditional granular filter materials, fiber filter materials have larger interface adsorption and can retain suspended matter; compared with foam ceramic filters, they have smaller pore sizes and higher filtration accuracy; compared with organic fiber filters, they have Better thermal stability, chemical stability and thermal shock resistance. Therefore, ceramic fiber materials have been widely used in air purification, high-temperature flue gas filtration, diesel exhaust micro-filter capture, chemical filtration, and metal liquid filtration due to their high strength, good thermal shock resistance, and chemical corrosion resistance. . Ceramic fiber filters can be divided into ceramic fiber composite membrane materials, ceramic fiber paper, ceramic inner mesh (cloth), and ceramic fiber filter bodies. The manufacturing process and application range of each material are different, which largely meets the requirements of filtration standards in various production scenarios. Ceramic fiber filtration technology can reduce atmospheric environmental pollution and human harmful factors in air purification, high-temperature flue gas filtration, and diesel exhaust micro-filtration capture. It can reduce the waste rate and reduce the generation of invalid waste in metal liquid filtration and chemical filtration. Energy conservation and environmental protection all play an important role.
Ceramic Fiber Board
Application as a sound-absorbing sound insulation material:
Ceramic fiber products are porous aggregates of fine fibers, which have excellent sound absorption and sound insulation performance. Firstly, because the fiber product itself has many tiny pores connected between the fibers, when the sound wave is incident on the fiber material and propagates inside, the viscous resistance of the air in the pores and the frictional resistance between the fibers will A part of the acoustic energy is converted into heat energy to form a loss. Secondly, when the air in the pores is compressed, the temperature of the surrounding environment increases, and the temperature decreases when the air is sparse, and the fiber's heat conduction will lose some of the sound energy. Ceramic fibers are mainly made of cotton board products as sound absorption materials. Except for the ultra-fine glass wool board and slag cotton board, which have low sound absorption coefficients, the average sound absorption coefficient of other ceramic fiber boards, All of them are higher than 0.80, belonging to high sound absorption materials, and have been widely used in industries, construction, transportation and other fields. It is a sound-absorbing product worthy of promotion in isolating noise pollution.
Although ceramic fiber products play an important role in high-temperature industries and other fields, there is nothing perfect in the world, and its disadvantages cannot be ignored. The most prominent is that ceramic fiber materials are relatively soft and require protective materials. During the construction and installation process It is easy to cause dust, irritate the skin, and there is inhalability, which will cause certain harm to the ambient air and human body during the manufacturing process. In this respect, it is necessary to continuously improve the performance of the product without changing the superiority of the ceramic fiber itself in practice. "Remove its dross and take its essence" is the purpose of maintaining the vitality of sustainable development of anything.
