Infrared radiation ceramics are applied functional materials produced by the combination of the development of infrared technology and the traditional ceramic industry. It mainly uses inorganic compounds and trace metals or specific natural ores mixed in different proportions respectively, and ceramic materials with high emissivity and radiation intensity in a certain infrared band range after high temperature sintering.
Generally, it is made by adding iron, diamond, nickel, manganese oxide, etc. or other metal oxides, carbides or nitrides with high full emissivity/single emissivity in the infrared region to the ceramic matrix, which is prepared by batching, molding and high-temperature sintering Ceramic material.
Application of infrared radiation ceramic material
①Used as a low-carbon material
In industrial production, infrared radiation ceramic materials are more obvious in energy saving and heating. For example, it is applied to the inner layer of heating materials in industrial production to improve the thermal conductivity of heating equipment and improve the energy efficiency of the equipment. In addition, the ceramic material itself has the advantages of high temperature resistance, corrosion and oxidation resistance, which can minimize the capital investment for equipment for enterprises.
② Applied to the manufacture of antibacterial health products
The ceramic material with high infrared radiation has the effect of promoting blood circulation and circulation, obviously improving the immunity of the human body and the tissue regeneration ability of the cells. In addition, the cell walls of organisms can be directly penetrated by infrared radiation, which plays a role in inhibiting the growth and reproduction of bacteria. In the medical field, infrared radiation ceramic materials will be used to manufacture medical devices to enhance the vitality of human cells (such as medical physiotherapy instruments); this material is used in the manufacture of antibacterial underwear and infrared slimming clothes in people's daily lives.
③Improve the heat dissipation of the spacecraft
In the aerospace field, the external temperature of the aircraft can be as high as 1000 ℃ or more, so the high infrared radiation ceramic material with outstanding heat dissipation effect on the surface coating can effectively prevent the rise of external temperature, strengthen the heat dissipation effect, and ensure the normal operation of the spacecraft. The emergence of high-infrared radiation ceramic materials has contributed greatly to the development of my country's aerospace industry.
④As an environmentally friendly architectural coating
The application of high infrared radiation ceramic materials to interior decoration materials has the functions of antibacterial and purification of indoor air, and belongs to environmentally friendly energy-saving materials. A good heat dissipation function can and can also relieve the indoor temperature in summer.
⑤Used as fuel activation material
Studies have shown that the use of room temperature infrared radiation ceramics as a fuel activator, connected to the oil circuit near the internal combustion engine, and then using the infrared radiation radiated at room temperature can activate fuel molecules, improve the internal energy of fuel molecules, thereby increasing power performance to achieve The purpose of saving fuel and reducing the emission of toxic gases in the exhaust gas. This is of great significance for the treatment of automobile exhaust.
