Aviation engine carbon deposit cleaning agent and preparation method thereof

Abstract

The invention provides an aviation engine carbon deposit cleaning agent and a preparation method thereof. The aviation engine carbon deposit cleaning agent comprises the following components in parts by weight: 10-25 parts of alcohol ether solvent, 5-10 parts of closed dodecylbenzene sulfonic acid, 2-8 parts of a sophorolipid biosurfactant, 2-5 parts of alkenyl succinic anhydride, 2-5 parts of a complexing agent, 2-5 parts of a ternary polycarboxylic acid composition, 1-3 parts of a compound corrosion inhibitor, 1-10 parts of an alkalinity improver, 0.1-1.0 part of a defoaming agent and 50-70 parts of water. The aviation engine carbon deposit cleaning agent is suitable for various assemblies made of different materials in an engine, can protect all the assemblies of the engine from being corroded, oxidized and discolored, meanwhile, removes carbon deposit and dirt on all the assemblies of the engine thoroughly, and guarantees a good cleaning effect.

Description

technical field [0001] The invention belongs to the technical field of aviation engine cleaning, and in particular relates to an aviation engine carbon deposit cleaning agent and a preparation method thereof. Background technique [0002] With the rapid development of modern industrial aerospace, the cleaning of carbon deposits in engines has attracted more and more attention from all aspects. The fuel and air in the combustion chamber of the engine are mixed and burned. Due to atomization and other factors, part of the smoke generated after combustion will form carbon deposits and deposit on objects. Because the composition of carbon deposits is relatively complex, it mainly contains hydroxy acids, asphaltenes, Oil coke and ash, etc. These carbon deposits are generally cationic adsorbents, and their cations are losing one or several electrons, making the outermost electrons reach a stable structure of 8 or 2 electrons. The larger the atomic radius, the greater the ability ...

AI Technical Summary

Problems solved by technology

The mechanical method is generally mechanical tool cleaning, soft and hard abrasive cleaning. This method has low productivity, and it is not easy to completely remove the carbon deposits on the parts that are difficult to reach. It will also leave scratches on the surface and become a new carbon deposit formation center. ;Chemical methods generally use strong alkali and strong acid cleaning, which will cause irreversible damage to the alloy layer of the parts

The existing chemical carbon deposit cleaners are mainly anionic surfactants and hydrophilic solvents, but the removal effect of carbon deposits is not thorough, and it is easy to block the antifreeze piston, and some need to be soaked for a long time to remove carbon deposits. lead to its limited use
