High-temperature-resistant far-infrared surface radiation material
The Xuchang Infrared Technology Research Institute Co., Ltd. is located on Yongxing East Road, Xuchang High-Tech Industrial Development Zone (Zhongyuan Electrical Valley), Henan, China. It was formerly the Xuchang Infrared Technology Research Institute and is now one of the influential infrared heating research institutions in China.
I am from1979Year10Since its inception last month, adhering to“Highlight strengths, stringent quality control, enhanced service, strive for excellencel”The guiding philosophy. With robust technical strength, a highly qualified workforce, and a spirit of innovation, Xuchang Infrared Institute has developed and produced a series of infrared products of leading levels. Main products include: a series of infrared radiation (absorption) coatings, infrared heating elements, infrared radiation heating modules (plates), infrared radiation heating furnaces (boxes), rapid infrared radiation heaters, and a series ofgEnd infrared heating experimental equipment, series of infrared heating controllers, etc.
Xuchang high-temperature far-infrared radiation coating is a special functional energy-saving coating with high-temperature resistance, strong radiation rate, corrosion resistance, and high wear resistance. It is developed over many years by our company. The coating is processed using nano-dispersed synthesis technology and forms a dense ceramic radiation coating on high-temperature kiln furnaces and inner linings. It optimizes the kiln and furnace coatings, enhancing the energy utilization of the kiln and furnace.
Industrial kilns, furnace chambers, and boilers, usually operate at combustion temperatures of1000℃The above high temperatures require furnace structural materials such as refractory bricks, quartz sand, clay bricks, castables, ceramic fibers, and more. These materials serve as both structural components and insulating, wear-resistant, and erosion-resistant materials. They also participate in the radiant heat exchange process. Their radiant heat properties and insulating capabilities determine the furnace's thermal efficiency, making it challenging for a single material to meet the requirements of robust structural integrity, high insulation, and high radiation.
Generally speaking, when the temperature within the furnace and combustion chamber is900℃At this point, heat transfer is primarily by radiation, with radiant heat transfer being dominant over convection.15Multiple times, accounting for80%Above. The wavelengths of high-temperature radiant energy are mostly concentrated in1~5μmBands, such as1000℃And1300℃At that time, there were76%And85%The radiant energy is concentrated within this band, and common refractory materials have a low emissivity in this range. The Xuchang high-temperature far-infrared radiation coatings,1~15μmThe emission rate is very high within the spectral range.
The emissivity of refractory materials is generally at room temperature0.6~0.8As the furnace temperature rises, there will be a significant decrease. Only under high temperatures...0.4~0.5And the Xuchang high-temperature far-infrared radiation coating can maintain0.88The above infrared emissivity.
According to Kirchhoff's law, the absorption rate of a material is equal to its emissivity. As the emissivity of an object's surface increases, so does its ability to absorb heat. Since heat transfer is primarily radiant under high-temperature conditions, when the surface of the heated object is coated with a nanometer-high emissivity coating,jEnhanced the ability of the heated object to absorb and emit heat, under the same heating conditions, the improved heat transfer capability will inevitably greatly enhance the energy utilization efficiency, thereby achieving the goal of energy saving.
Our company, based on the actual operating conditions of the furnace bodies mentioned, has conducted over a thousand tests and specific furnace usage validations. Our high-temperature infrared radiation coating, through its infrared radiation coating, improves the heat exchange conditions within the furnace, enhancing the combustion temperature and uniformity inside the furnace chamber. This results in more complete fuel combustion, thereby increasing thermal efficiency, significantly boosting the thermal efficiency of refractory materials, reducing energy consumption, conserving energy, and extending the service life of the furnace lining.
Additionally, Xuchang's high-temperature far-infrared radiation coatings on high-temperature metal pipes can accelerate the transfer of heat from the surrounding environment to the inside of the pipes, enhancing heat exchange. Xuchang Infrared Institute will continue to focus on the research and development of infrared radiation heating technology to improve safety and efficiency.qEfficiency, reliability, and system lifespan, providing for you,zPure infrared heating technology solutions.
