High temperature corrosion-resistant ceramic coating under the flame wear-resistant anti-corrosion layer

China Coatings Online News Information:
The occurrence of high temperature corrosion of metal under combustion, metal coating surface non-metallicization, its thermal efficiency began to decline, due to the metal coating surface non-metallicization of the melting point is low, easy to mineralize with mineral particles in the flue gas flow Reaction, and even the formation of glass body, resulting in serious sticky ash, slag, coking, thereby reducing heat exchange efficiency, metal coating resistance to high temperature abrasive wear performance is lower than ceramic coating, so research and development and production of high temperature corrosion-resistant ceramic coating coating is the boiler furnace under the flame energy saving the best material.
combustion is a rapid heating and luminescence oxidation reaction between combustibles and oxygen or air, which occurs in the form of flames at temperatures of up to 2000 degrees C. The transfer of momentum, heat and mass is carried out between fuels such as coal, oil and natural gas, oxygen and combustion products, forming a complex structure of flame with multiple parts concentration gradient and unequal temperature flow. High temperature anti-corrosion coating engineers pointed out that combustion has a complete combustion and incomplete combustion, but both have a strong corrosive to the material, the fuel is fully burned, the composition of flue gas is CO2, SO2, H2O, N2, and O2, some flue gas will also contain fluorine ions. When the fuel is not fully burned, some carbon produces carbon monoxide, and may also produce a small amount of hydrogen and hydrocarbon CmHn, so when the fuel is not fully burned, the flue gas components in addition to CO2, SO2, H2O, N2, and O2, there are a small amount of CO, H2, CmHn and so on.
coating in the face of high temperature combustion flame, high temperature anti-corrosion coating is suitable for high temperature corrosion environment, high temperature oxygen corrosion, high temperature sulfur corrosion, high temperature flame flushing, high hardness adhesion. High temperature anti-corrosion coating temperature breakthrough 2300 degrees C high temperature environment corrosion resistance, now there is a corrosion-resistant coating, temperature resistance can reach the temperature of the flame, can withstand high temperature flame long-term barbecue, anti-corrosion and oxidation performance is good, high hardness, can successfully solve the above high temperature furnace metal corrosion problems! Joint Beijing institutions and military research institutes, after many years, tens of thousands of high temperature tests, high temperature anti-corrosion coatings, with exclusive patented technology, the only domestic production and sales enterprises. High temperature anti-corrosion coating temperature resistance can reach 2300 degrees C, can be long-term fire-resistant barbecue, anti-corrosion effect in the fire is good. High temperature anti-corrosion coating belongs to water-based inorgic paint, paint can be long-term anti-corrosion in fire, hardness of 8H, paint is water-based inorance environmental protection paint, at room temperature and high temperature without any harmful substances volatile, green environmental protection, non-polluting, paint temperature self-curing, its physical properties, chemical properties and use performance have reached the international advanced level.
High temperature anti-corrosion coating brushed on high temperature furnace body metal, in the high temperature flame environment can effectively protect high temperature furnace body metal corrosion resistance, improve acid and alkali resistance, protect metal from antioxidant, closed protection and other effects, to overcome ordinary anti-corrosion coating in high temperature conditions extremely unsuitable, temperature resistance is not enough, easy to produce skin, cracking, color change and other defects. High coating stability, impact resistance and wear resistance, high temperature anti-corrosion coatings in high temperature environment will react with other active molecules, so that the furnace body life is longer, resulting in industrial production continuity and improve product production. Excellent performance of high temperature anti-corrosion coatings also enhances their scope of application. Over the past few years, high temperature anti-corrosion coatings have been widely used in aerospace, petroleum and petrochemical, metallurgical light industry, electricity, military systems, suitable for chimneys, high-temperature steam pipes, heat exchangers, high-temperature kilns, petroleum and petrochemical cracking equipment, engine components and exhaust pipes resistant to high temperature corrosion. With the development of science and technology level, the improvement of industrial technology, corrosion resistance and temperature range, high temperature anti-corrosion coatings will gradually expand the use of water-based ceramic high temperature anti-corrosion coatings for high temperature corrosion effect is very good.
