AI Technical Summary

Problems solved by technology

Most of the water-based cleaning agents that have been gradually developed in recent years have better cleaning functions, but the surfactants used still have problems such as phosphorus and fluorine; at the same time, the cleaning agents contain more volatile organic substances and ozone-depleting substances. etc., causing a lot of harm to the atmospheric environment and humans; some water-based cleaning agents containing strong alkaline substances have potential corrosion on substrates or equipment; and the low flash point of volatile organic substances also makes the daily maintenance and repair of aero-engines safe Sex poses serious challenges

Abstract

The invention discloses a carbon deposition microemulsion type anti-corrosion cleaning agent for an aero-engine. The aero-engine carbon deposit micro-emulsion type anti-corrosion cleaning agent is prepared from of a hydrophilic surfactant, a lipophilic surfactant, a cosurfactant, a coupling agent, an oil phase, a corrosion inhibition additive and the balance of deionized water according to certainproportion.The mass percent of the components are 5-30% of the a hydrophilic surfactant, 1-10% of the lipophilic surfactant, 0.5-6% of the cosurfactant, 5-20% of the coupling agent, 8-20% of the oilphase, 0.2-3% of the corrosion inhibition additive and the balance of deionized water. The cleaning agent has the technical characteristics of low foam, no phosphorus, no fluorine, high flash point, alkalescence and environmental protection, has a good cleaning effect on carbon deposits, heavy oil stains, dust and the like on the surfaces or in the parts of the aero-engine, and also has rust-proofand corrosion-proof functions.

Description

technical field [0001] The invention relates to the technical field of industrial cleaning, in particular to a microemulsion type anticorrosion cleaning agent for carbon deposits and heavy oil stains of aero-engine parts. Background technique [0002] Aviation engines often operate at high temperatures above 1000°C. When aviation fuel is catalyzed by oxygen and metals and the temperature is high, it is easy to generate colloids and product after a series of reactions such as oxidation, pyrolysis, cracking, dehydrogenation, coking and polymerization. Carbon and other substances, these colloids, carbon deposits and other sedimentary substances, and some sand, dust and oil stains are easy to block nozzles and corrode blades, resulting in reduced engine performance and wear and tear of components, which in turn leads to increased fuel consumption of the aircraft, severe flame ablation, and exhaust gas. Pollutants have increased significantly, seriously affecting the service life...
