Comprehensive performance will become the standard for aircraft coating market

The birth of the aircraft has provided people with convenient conditions for travel and transportation. Since the invention of the aircraft, it has increasingly become an indispensable delivery tool for modern civilization. It has profoundly changed and influenced people's lives. The aircraft soars between the blue sky and the white clouds. At the same time, it also has to withstand the effects of various climate changes. Therefore, the surface of the aircraft and all parts need the protection of the external coating.

Analysis: What is the aircraft coating aircraft coating as the name suggests is the coating used on the aircraft, according to the function can be divided into stealth coatings and protective coatings, which invisible coatings and protective coatings can be divided into multiple sub-categories by function, such as plasma stealth coatings, infrared Stealth coatings and protective coatings include fire retardant coatings, anti-icing coatings, anti-static coatings, etc. The following editors provide a brief introduction to some functions of aircraft coatings.

Declassified Aircraft Stealth Paint Stealth Coating is a material used for aircraft, warships, tanks and other equipment appearances to perform anti-radar detection and prevent electromagnetic wave leakage or interference. Stealth materials and stealth design are organically combined to form a new technology, namely stealth technology. . Stealth technology requires hidden light, hidden electricity, hidden magnetic, occult sound, and hidden infrared. It is an integrated technology.

Stealth plasma stealth paint to create a very strong stealth aircraft plasma stealth aircraft is the use of plasma stealth paint developed a stealth performance of the aircraft. Plasma stealth coatings use radioactive isotopes such as *-210, yttrium-242, and yttrium-90 as raw materials to emit strong alpha rays during flight of aircraft. High-energy particles cause air outside the surface of the aircraft to ionize to form plasma layers. , Infrared radiation has a very good absorption effect, and its absorption properties make the signal have attenuation of 17 dB in the range of 1-20 GHz. After the electromagnetic waves radiated by the enemy detection radar irradiate the plasma cloud around the aircraft, there are mainly two phenomena: First, part of the electromagnetic wave energy is absorbed by the plasma cloud. Because the electromagnetic wave interacts with the charged particles of the plasma when it passes through the plasma cloud, it transfers the energy to the charged particles, and its energy is greatly attenuated; secondly, the plasma cloud can make the electromagnetic wave produce diffraction, and the electromagnetic wave bypasses the plasma cloud lip , continue to radiate forward, no reflection, which will greatly reduce the reflection of electromagnetic signals, making it difficult for radar to find the plane hidden in the plasma cloud.

Infrared Stealth Coating Escape Radar Reconnaissance It is understood that infrared stealth coatings are nanometer-scale carbon-based iron powder, nickel powder, ferrite powder modified organic coatings, and nano-metal (Fe, Co, Ni) or alloy composite powders thereof are adopted. In the multi-phase composite method, nano-oxide (Fe3O4, Fe2O3, ZnO, NiO2, TiO2, MoO2, etc.) powders, nano-graphite, nano-silicon carbide, and mixture powders are used for stealth radar wave absorbents. Because nano-ultrafine powders have a large specific surface area, they can absorb electromagnetic waves. At the same time, the size of nano-particles is much smaller than that of infrared and radar waves, and the transmittance of waves is very large, so it can not only absorb radar waves but also absorb visible-light infrared rays. The finished coating can escape radar reconnaissance over a wide frequency range and also has an infrared stealth effect.

Declassification of Aircraft Protective Coatings Anti-icing Coatings Effectively Improves Aircraft Safety Performance It is understood that in the recent years, with the active exploration and efforts of countries and enterprises, aircraft coatings have achieved remarkable results. It is reported that Ames has introduced an AMESShield protective coating. The coating can provide sufficient protection and protection for aircraft parts and greatly reduce the risk of foreign parts damage (FOD). The surface of this paint also has the function of icing on the ice, so that the aircraft parts will not be frozen in the high altitude and cold environment, which effectively improves the safety performance of the aircraft.

New Generation of UV-curable Aircraft Coatings Cured in Minutes The U.S. Air Force The military imposes strict and systematic standards on aircraft paints. Under normal circumstances, the aircraft's skin coatings are required to cure within 72 hours to ensure normal flight. . The last process adds various logos to the aircraft, including the tail identification code, the American flag of the fuselage, and the words of the United States Air Force. The importance of the high performance of the required paint can be imagined. For the needs of the military, Bayer MaterialScience, USA, H&S Autoshot, and Deft Inc. have introduced UV-curable coatings that allow them to cure coated letters in minutes.

The new technology of nano-composite coating can effectively improve the life of the coating. Due to environmental and other factors, the original imported high-grade paint will be powdered and peeled off within two years after the aircraft skin coating is applied. The local corrosion of the skin not only reduces the safety of the aircraft, but also increases the maintenance time and greatly reduces the use efficiency. It is understood that a nanometer composite coating technology has effectively improved this problem with the efforts of researchers from the Institute of Environmental Corrosion Research, Shenyang Institute of Metals Materials, Chinese Academy of Sciences. After applying to a large transport aircraft, two large aircraft have been used. In the 4 months of the month, the overall condition of the coating has so far been good.

Conclusion: At present, with the strengthening of the comprehensive functional requirements for aircraft coatings, domestic and foreign companies are stepping up the development and production of related coating products, such as the blade erosion protection of aircraft engines developed by a domestic company. Coatings, although the coatings have good abrasion resistance and extrusion resistance properties, the coating did not consider the coating's antifreeze and anti-icing performance during R&D, which may cause problems in the aircraft in high temperatures. Therefore, as a coating product in the cutting-edge field, companies must be well-considered in design and research and development. From the perspective of future aviation, coatings will become increasingly demanding. Editors believe that the overall performance of aircraft coatings will be excellent. Become a standard for future market considerations.
