Industrial kilns, furnaces, and boilers usually burn at high temperatures above 1000 ℃. The structural materials of the furnace body are mainly various refractory materials such as high bricks, quartz sand, clay bricks, castables, ceramic fibers, etc. They are not only the structural materials of the furnace body, but also participate in the radiation heat exchange process. Their thermal radiation and insulation properties determine the thermal efficiency of the kiln, making it difficult for a single material to achieve a solid structure High insulation and radiation requirements. Studying the laws and applications of thermal radiation is of great significance for the energy-saving of furnaces and kilns.
In response to the above challenges, ZS-1061 high-temperature far-infrared radiation coating: high temperature resistance, strong radiation rate, corrosion resistance, and high wear resistance. By coating the infrared radiation of the coating, the heat exchange conditions in the furnace are improved, the combustion temperature and uniformity in the furnace are increased, the fuel combustion is more sufficient, the heating efficiency is achieved, the furnace temperature is increased, energy conservation is saved, and the lining inside the furnace is protected to extend the service time.
When the working temperature of the heating furnace is 700 ℃, the main heat transfer is radiation (over 90%). With this product, the radiation rate of the furnace body increases from 0.35 to 0.88 at high temperatures, and the surface absorption of heat inside the furnace body increases significantly. The radiation rate of the far infrared radiation coating of Jinshi is 96% at high temperatures, resulting in a significant increase in the temperature of the heating furnace body. Beijing Zhisheng Weihua 1061 High Temperature Far Infrared Radiation Coating ZS is a special functional energy-saving coating with high temperature resistance (up to 1700 ℃), strong radiation rate (0.95), corrosion resistance, and high wear resistance. After curing, the coating forms a solid glaze like coating, which has high absorption rate and converts the absorbed heat energy into far infrared electromagnetic waves for radiation, causing the furnace or medium to heat up and accelerate. Greatly improving the thermal efficiency of the furnace, reducing heat loss, and achieving the goal of energy conservation. By coating with paint and infrared radiation, the heat exchange inside the furnace is improved, the temperature field strength and uniformity inside the furnace are increased, and fuel combustion is more fully achieved, thereby increasing thermal efficiency, greatly improving the thermal efficiency of refractory materials, reducing energy consumption, and saving energy. The strong radiation materials contained in coatings emit highly penetrating far-infrared waves at high temperatures, causing the molecules of the heated object to absorb the waves and generate energy level transitions. The absorbed energy is evenly heated, reducing heating time and fully utilizing thermal energy.
At the same time, the coating is processed using nano dispersion synthesis technology. The ultrafine and nano sized nano coating can penetrate into the refractory matrix, thereby reducing the porosity and increasing the volume density of the refractory. The hard glaze layer formed after the coating is cured improves the compressive strength and flexural strength of the refractory material. The reduction of porosity and the hard coating improve the ability of the refractory to resist deformation under high temperature loads, The high-temperature creep performance of grid bricks has been greatly improved, which is very beneficial for improving the service life of industrial high-temperature kilns.
