Embodiment 1

[0042] Without loss of generality, the present invention provides an aircraft engine cleaning agent, which is prepared from the following raw materials in parts by weight: 10-20 parts of carbon deposit cleaning agent, 35-50 parts of detergent and 6-12 parts of corrosion inhibitor; Among them, according to the parts by weight, the detergent is configured from the following raw materials: 8-20 parts of sodium lauryl sulfate, 5-16 parts of fatty alcohol polyoxyethylene ether, 1-8 parts of alkanolamide, 1 part of Span -5 parts, 50-70 parts of deionized water; the corrosion inhibitor is an organic corrosion inhibitor.

[0043] The aircraft engine cleaning agent has the advantages of rapidly dissolving carbon deposits, dirt, oil stains and salt stains under normal temperature and pressure, is non-corrosive, has high stability, is not easy to deteriorate and has no pollution. It should be noted that the carbon deposit cleaning agent and corrosion inhibitor used in this embodiment are...

Embodiment 2

[0050] In this example, on the basis of Example 1, the carbon deposit cleaning agent is prepared from the following raw materials in parts by weight: 2-10 parts of isopropanol, 6-15 parts of ethanolamine, 25-40 parts of triethanolamine, penetrating agent 1-5 parts, 1-5 parts of Tween, 1-5 parts of polyether, 40-50 parts of kerosene.

[0051] The present invention achieves the technical effect of further efficient cleaning of carbon deposits by adopting a carbon deposit cleaning agent composed of isopropanol, ethanolamine, triethanolamine, penetrant, Tween, polyether and kerosene, and can be more effective Cleans carbon deposits deposited in the gas passages of aviation gas turbine engines. After cleaning the carbon deposit stains within 1 square meter, the residual carbon deposit is less than 10%.

[0052] Preferably, in a preferred technical solution of this embodiment, the carbon deposit cleaning agent is prepared from the following raw materials in parts by weight: 2 parts...

Embodiment 3

[0058] In this embodiment, on the basis of Embodiment 1, the carbon deposit cleaning agent is configured from the following raw materials in parts by weight: 10-30 parts of sodium carbonate, 2-10 parts of potassium dichromate, and 5-10 parts of sodium silicate , 15-40 parts of fatty alcohol polyoxyethylene ether, 50-70 parts of kerosene.

[0059] The present invention achieves a further efficient cleaning of mixed stains composed of carbon deposits and oil stains by using a carbon deposit cleaning agent composed of sodium carbonate, potassium dichromate, sodium silicate, fatty alcohol polyoxyethylene ether and kerosene The technical effect can more effectively clean the carbon deposit deposited in the gas channel of the aviation gas turbine engine. The present invention uses the carbon deposit cleaning agent with the above-mentioned composition ratio to help remove the carbon deposits that are sticky by oil stains and stubbornly adhered to the metal surface, so as to improve t...

Abstract

The invention relates to the technical field of engine cleansing agents, in particular to an aircraft engine cleansing agent and a preparing method thereof. The aircraft engine cleansing agent has the advantages of fasting dissolving deposited carbon, dust dirt, oil contamination and salt marsh at normal temperature and normal pressure and being noncorrosive, high in stability, not prone to deterioration and free of pollution. The aircraft engine cleansing agent is prepared from, by weight, a deposit carbon cleansing agent, a clearing agent and corrosion inhibitor. The clearing agent is prepared from, by weight, lauryl sodium sulfate, fatty alcohol polyoxyethylene ether, alkylolamide, span and deionized water; the corrosion inhibitor is organic. The preparing method of the aircraft engine cleansing agent includes the following steps that the deposit carbon cleansing agent is weighed and added into a reaction still to be heated to 40-60 DEG C; the clearing agent is weighed, added into the reaction still and fully stirred for 15-20 min; the corrosion inhibitor is heated to 50-70 DEG C, added into the reaction still and stirred uniformly; the reaction still is sealed and stands for 2 h to obtain the finished aircraft engine cleansing agent product.

Description

technical field [0001] The invention relates to the technical field of engine cleaning agents, in particular to an aircraft engine cleaning agent and a preparation method thereof. Background technique [0002] After the aircraft engine in the prior art works for a long time, a large amount of carbon deposits, salt stains, dirt and oil stains are usually deposited in the body. The cleaning agents in the prior art usually have a single cleaning function and poor cleaning effect, and even special cleaning for specific types of stains usually takes a long time to clean. The cleaning process of the engine cleaners in the prior art usually requires a lot of labor and wastes a lot of water resources. When it is necessary to clean complex stains containing at least two or more components of carbon deposits, salt stains, dirt and oil stains, it is also necessary to mix at least two or more brands of cleaning agents to achieve the technical effect of comprehensive decontamination. S...
