Problems solved by technology

[0002] Aircraft engine blades are an important part of aircraft engine engines, and have strict requirements on their fatigue resistance, high temperature resistance, and corrosion resistance. Since aircraft engine blades work at high temperatures for a long time, disulfide will remain on the pressure surface coating. A mixture of molybdenum and some other stains, which can increase the corrosion of aircraft engine blades and pose a safety hazard if not cleaned regularly
At present, there are few mature and effective automatic aircraft engine blade cleaning methods at home and abroad, and most of them use manual methods for cleaning in China.
The cleaners use isopropanol as the cleaning material, and use brushes to repeatedly scrub the blades of the aircraft engine. Obviously, the working hours are long and the labor intensity is high.
Moreover, isopropanol is a colorless and transparent organic compound, which has certain carcinogenicity and will cause great harm to the human body.
