Problems solved by technology

[0002] During the long-term use of the aero-engine, due to the large amount of air passing through the blades at high speed, especially in harsh environments, the surface is prone to form carbon deposits formed by salt mist, dust, and oil in the engine, which firmly adhere to the The surface of the blade is not easy to remove, which reduces the efficiency of the engine
[0003] When repairing, it is necessary to clean the blade. The cleaning liquid cannot damage the surface state of the blade and the coating on the blade surface. Use petroleum solvent and surfactant to clean, and the oil removal effect is better, but the stubborn pollutants are not easy to remove; use alkaline cleaning solution , has a good cleaning effect, but it is easy to damage the surface state of the blade
