Abstract

The invention relates to an airplane skin external surface cleaning compound. The airplane skin external surface cleaning compound comprises a surfactant, a chelating agent, a corrosion inhibitor, inorganic base and a solvent. The airplane skin external surface cleaning compound comprises the following components by mass percentage: 18-34% of the surfactant, 8-13% of the complexing agent, 5-9% of the corrosion inhibitor, 3-8% of the inorganic base, and the balance of the solvent. The cleaning compound employs a complex formulation technology, the components ratio is reasonable, a pollutant deposited on the airplane skin external surface is thoroughly cleaned, effect is good, efficiency is high, the cost of the cleaning compound is low, no corrosion is generation on a body of the airplane, no pollution is generated on human body and environment, the cleaning waste liquid can be directly discharged, and the cleaning compound has the advantages of safety and environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of aircraft maintenance, in particular to an aircraft skin outer surface cleaning agent. Background technique [0002] During the parking and flight of the aircraft on the ground, the outer surface of the aircraft skin is inevitably damaged by multiple channels such as the atmosphere, the ground, and fuel exhaust, and deposits of pollutants such as smoke, dust, insect grease, and oil stains are formed on the outer surface of the skin. These deposited pollutants not only affect the appearance of the aircraft, but also reduce the surface finish, increase the frictional resistance of the airflow, increase flight resistance and fuel consumption, and even become corrosion-inducing factors in severe cases, leading to localized corrosion such as pitting corrosion and crevice corrosion. , Reduce the strength of the skin structure. Therefore, removing the deposited pollutants on the outer surface of the aircraft ski...
